This fixed an issue that caused TX to be blocked for 3-5 seconds. On some RTL8821AE units, this change causes soft lockups to occur on boot. For that reason, the portion of the earlier commit that applied to rtl8821ae is reverted. Kernels 4.1 and newer are affected. See http://marc.info/?l=linux-wireless&m=144373370103285&w=2 and https://bugzilla.opensuse.org/show_bug.cgi?id=944978 for two cases where this regression affected user systems. Note that this bug does not appear on any of the developer's setups. For those users whose systems are affected by the TX blockage, but do not lock up on boot, a module parameter is added to disable the interrupt clear Fixes: 1277fa2ab2f9 ("rtlwifi: Remove the clear interrupt routine from all drivers") Signed-off-by: Larry Finger Cc: Stable [V4.1+] Signed-off-by: Kalle Valo --- drivers/net/wireless/rtlwifi/pci.h | 2 ++ drivers/net/wireless/rtlwifi/rtl8821ae/hw.c | 17 +++++++++++++++++ drivers/net/wireless/rtlwifi/rtl8821ae/sw.c | 5 +++++ drivers/net/wireless/rtlwifi/wifi.h | 3 +++ 4 files changed, 27 insertions(+) diff --git a/drivers/net/wireless/rtlwifi/pci.h b/drivers/net/wireless/rtlwifi/pci.h index d4567d1..5da6703 100644 --- a/drivers/net/wireless/rtlwifi/pci.h +++ b/drivers/net/wireless/rtlwifi/pci.h @@ -247,6 +247,8 @@ struct rtl_pci { /* MSI support */ bool msi_support;

The restore was broken due to my previous commit to move PN assignment into the driver. Sending the PN to the firmware still worked since we now use the counter that's shared with mac80211, but accessing it through the mac80211 API makes no sense now. Fix this by reading/writing the counter directly. This actually simplifies the code since we don't need to round-trip through the key_seq structure.

However, sk_get_filter() wasn't updated to test for this at the time when eBPF could be attached. Just throw an error to the user to indicate that eBPF cannot be dumped over this interface.

Without this patch, if the only instructions using r_X are of the BPF_LD | BPF_IND type, r_X would not be reset to 0, using whatever value was there when entering the jited code. With this patch, r_X will be correctly marked as used so it will be reset to 0 in the prologue code. This fix also makes the test "LD_IND byte default X" pass in the test_bpf module when the ARM JIT is enabled. Signed-off-by: Nicolas Schichan Signed-off-by: David S.

The FE PCM params come from hw_params ie from user, for a BE they also come from hw_params but from BE-link fixups. So based on PCM params required driver has to find a converter module (src/updown/format) and then do the conversion and calculate PCM params in these pipelines In this patch we add the helper modules which allow driver to do these calculations.

The creation rule is: - Create Pipe - Add modules to Pipe - Connect the modules (bind) - Start the pipes Similarly destroy rule is: - Stop the pipe - Disconnect it (unbind) - Delete the pipe In driver we use Mixer, as there will always be ONE mixer in a pipeline to model a pipe. The modules in pipe are modelled as PGA widgets. The DAPM sequencing rules (mixer and then PGA) are used to create the sequence DSP expects as depicted above, and then widget handlers for PMU and PMD events help in that. This patch adds widget event handlers for PRE/POST PMU and PRE/POST PMD event for mixer and pga modules. These event handlers invoke pipeline creation, destroy, module creation, module bind, unbind and pipeline bind unbind Event handler sequencing is implement to target the DSP FW sequence expectations to enable path from source to sink pipe for Playback/Capture.

It uses the newly added ASoC topology core to parse the topology information (controls, widgets and map) from topology binary. Each topology element passed private data which contains information that driver used to identify the module instance within firmware and send IPCs for that module to DSP firmware along with parameters.

This was not observed or reproducable yet. This patch adds locking to critical use of task_recv and task_send to avoid killing tasks that already left the NBD thread functions. This lock is only acquired if a timeout occures or the nbd device starts/stops.

The iteration is performed by walking bdi->cgwb_tree; however, the tree only indexes wb's which are currently active. For example, when a memcg gets associated with a different blkcg, the old wb is removed from the tree so that the new one can be indexed. The old wb starts dying from then on but will linger till all its inodes are drained. As these dying wb's may still host dirty inodes, writeback operations which affect all wb's must include them. bdi_for_each_wb() skipping dying wb's led to sync(2) missing and failing to sync the inodes belonging to those wb's. This patch adds a RCU protected @bdi->wb_list which lists all wb's beloinging to that bdi. wb's are added on creation and removed on release rather than on the start of destruction. bdi_for_each_wb() usages are replaced with list_for_each[_continue]_rcu() iterations over @bdi->wb_list and bdi_for_each_wb() and its helpers are removed. v2: Updated as per Jan. last_wb ref leak in bdi_split_work_to_wbs() fixed and unnecessary list head severing in cgwb_bdi_destroy() removed.

For example, if a memcg domain has a significant amount of dirty memory, the above can lead to a value which is lower than the current amount in use which doesn't make much sense. In most circumstances, the above leads to a number which is somewhat but not drastically lower. As the amount of memory which can be readily allocated to the memcg domain is capped by the amount of system-wide clean memory which is not already assigned to the memcg itself, the number we want is the amount currently in use + min(headroom according to memcg, clean memory elsewhere in the system) This patch updates mem_cgroup_wb_stats() to return the number of filepages and headroom instead of the calculated available pages. mdtc_cap_avail() is renamed to mdtc_calc_avail() and performs the above calculation from file, headroom, dirty and globally clean pages. v2: Dummy mem_cgroup_wb_stats() implementation wasn't updated leading to build failure when !CGROUP_WRITEBACK.

This patch sets LDO1 regulator to always-on. This patch has a side effect of fixing another issue, HDMI DDC not working when SD card is not inserted: Why this happens is that the tpd12s015 (HDMI level shifter/ESD protection chip) has LS_OE GPIO input, which needs to be enabled for the HDMI DDC to work. LS_OE comes from gpio6_28. The pin that provides gpio6_28 is powered by vddshv8, and vddshv8 comes from VDD_SD. So when SD card is not inserted, VDD_SD is disabled, and LS_OE stays off. The proper fix for the HDMI DDC issue would be to maybe have the pinctrl framework manage the pin specific power. Apparently this fixes also a third issue (copy paste from Kishon's patch): ldo1_reg in addition to being connected to the io lines is also connected to the card detect line. On card removal, omap_hsmmc driver does a regulator_disable causing card detect line to be pulled down. This raises a card insertion interrupt and once the MMC core detects there is no card inserted, it does a regulator disable which again raises a card insertion interrupt. This happens in a loop causing infinite MMC interrupts.

The TBI register would therefore be accessed at a wrong (much bigger) address, not giving the expected result at all. This patch restores the correct behavior we had prior to the above one. The consequences of this bug are apparent when trying to access a PHY with the same address as the value contained in the initial value of the TBI register (normally 0); in that case you'll get answers from the internal TBI device (even though MDIO/MDC pins are actually *also* toggling on the physical bus!). Beware that you also need to add a fake tbi node to your device tree with an unused address. Notice how this fix is related to commit 220669495bf8b68130a8218607147c7b74c28d2b "powerpc: Add TBI PHY node to first MDIO bus" which fixed the behavior in kernel 3.3, which was later broken by the above commit on kernel 3.7.

But the fix did not remove this capability from the profile descriptor of the VF. This causes the VF driver to request this capability when it tries to create it's interface at probe time. This could potentailly cause the VF probe to fail if the FW enforces strict checking of the flags based on what was provisoned by the PF. This strict checking is not being done by FW currently but will be fixed in a future version. This patch fixes this issue by updating the VF's profile descriptor so that they match the interface capability flags provisioned by the PF.

The write with the new P1/P2 divider can itself disable VGA mode again without problems. I tested the behaviour on my 946GZ, and when manually frobbing the register with the display on, the behaviour is very clear. However I can't explain why this machine actually works. The P1/P2 divider changes caused by normal modesets do seem to make it through to the hardware somehow since I get a stable picture on the monitor with any resolution. Maybe it's the "three times for luck" stuff that somehow masks the problem, or something. But apparently there are machines (eg. Nick Bowler's G45) where that isn't the case and we fail to get the correct clock from the DPLL. Things used to work because we enabled VGA mode for disabled DPLLs, so when re-enabling the DPLL VGA mode was enabled just prior to the first register write, and hence the P1/P2 change went through without a hitch. That got changed in b8afb9113c51 drm/i915: Keep GMCH DPLL VGA mode always disabled in the name of consistency. In order to keep the consistency part, leave VGA mode disabled for disabled DPLLs, but turn it on just prior to updating the P1/P2 dividers to make sure the hardware picks up on the new values.

As the hardware pins the backing storage, the userptr becomes invalid and this raises a WARN when the clients tries to unmap its address space.

However, if a scatter/gather list entry is large enough to fit more than one large page, the address space for any subsequent large pages is not cleared of conflicting small page tables. This can cause legitimate mapping requests to fail with errors of the form below, potentially followed by a series of IOMMU faults: ERROR: DMA PTE for vPFN 0xfde00 already set (to 7f83a4003 not 7e9e00083) In this example, a 4MiB scatter/gather list entry resulted in the successful installation of a large page @ vPFN 0xfdc00, followed by a failed attempt to install another large page @ vPFN 0xfde00, due to the presence of a pointer to a small page table @ 0x7f83a4000. To address this problem, compute the number of large pages that fit into a given scatter/gather list entry, and use it to derive the last vPFN covered by the large page(s).

BockW had used SRU before, but it was pass through mode. This means it is same as SSI. And BockW "platform base" code was removed from upstream code. It is now supported via DT, but it doesn't use SRU. More detail, r8a7778.dtsi has "rcar_sound,src" entry, but no-one is using this feature today. SRU probing has no relation to this removing. This means there is no effect for DT compatibility, no issues on upstream kernel. Gen2 SRC was created from Gen1 SRU, these are similar but not same IP. Keeping Gen1 SRU in current driver is a little bit difficult, and no-one is using it today. Gen1 sound is still supported via SSI. Gen1 SRU support will be removed in the next kernel version.

We have now detected a bug in this mechanism. During link synchronization we use the arrival of any packet on the tunnel link to trig a check for whether it has reached the synchronization point or not. This has turned out to be too permissive, since it may cause an arriving non-last SYNCH packet to end the synch state, just to see the next SYNCH packet initiate a new synch state with a new, higher synch point. This is not fatal, but should be avoided, because it may significantly extend the synchronization period, while at the same time we are not allowed to send NACKs if packets are lost. In the worst case, a low-traffic user may see its traffic stall until a LINK_PROTOCOL state message trigs the link to leave synchronization state. At the same time, LINK_PROTOCOL packets which happen to have a (non- valid) sequence number lower than the tunnel link's rcv_nxt value will be consistently dropped, and will never be able to resolve the situation described above. We fix this by exempting LINK_PROTOCOL packets from the sequence number check, as they should be. We also reduce (but don't completely eliminate) the risk of entering multiple synchronization states by only allowing the (logically) first SYNCH packet to initiate a synchronization state. This works independently of actual packet arrival order.

Since the value so far only is used at the transmitting end of the link, we have not yet officially defined it as part of the protocol. Unfortunately, the field we use for keeping this value, bits 13-15 in in word 5, has turned out to be a poor choice; it is already used by the broadcast protocol for carrying the 'network id' field of the sending node. Since packet fragments also need to be transported across the broadcast protocol, the risk of conflict is obvious, and we see this happen when we use network identities larger than 2^13-1. This has escaped our testing because we have so far only been using small network id values. We now move this field to bits 0-2 in word 9, a field that is guaranteed to be unused by all involved protocols.

A request_queue's user can access the congestion state of the embedded bdi as long as it holds a reference to the queue. As such, it may access the congested state of a queue which finished blk_cleanup_queue() but hasn't reached blk_release_queue() yet. Because the congested state was embedded in backing_dev_info which in turn is embedded in request_queue, accessing the congested state after bdi_destroy() was called was fine. The bdi was destroyed but the memory region for the congested state remained accessible till the queue got released. a13f35e87140 ("writeback: don't embed root bdi_writeback_congested in bdi_writeback") changed the situation. Now, the root congested state which is expected to be pinned while request_queue remains accessible is separately reference counted and the base ref is put during bdi_destroy(). This means that the root congested state may go away prematurely while the queue is between bdi_dstroy() and blk_cleanup_queue(), which was detected by Andrey's KASAN tests. The root cause of this problem is that bdi doesn't distinguish the two steps of destruction, unregistration and release, and now the root congested state actually requires a separate release step. To fix the issue, this patch separates out bdi_unregister() and bdi_exit() from bdi_destroy(). bdi_unregister() is called from blk_cleanup_queue() and bdi_exit() from blk_release_queue(). bdi_destroy() is now just a simple wrapper calling the two steps back-to-back. While at it, the prototype of bdi_destroy() is moved right below bdi_setup_and_register() so that the counterpart operations are located together.

The problem is that the presence of the gpio- range property causes the gpio-tegra driver to defer probe (it needs the pinctrl driver to be ready). That's technically correct, but it causes a couple of issues: - The keyboard on Chromebooks stops working. The reason for that is that the gpio-tegra device has not registered an IRQ domain by the time the EC SPI device is registered, hence the interrupt number resolves to 0. This is technically a bug in the SPI core, since it should really resolve the interrupt at probe time and defer if the IRQ domain isn't available yet. This is similar to what's done for I2C and platform device already. - The gpio-tegra device deferring probe means that it is moved to the end of the dpm_list. This list defines the suspend/resume order for devices. However the core lacks a way to move all users of the gpio-tegra device to the end of the dpm_list at the same time. This in turn results in a subtle bug on Jetson TK1, where the gpio-keys device is used to expose the power key as input. The power key is a convenient way to wake the system from suspend. Interestingly, the gpio-keys device ends up getting probed at a point after gpio-tegra has been probed successfully from having been deferred earlier. As such the driver doesn't need to defer the probe itself, and hence the device isn't moved to the end of the dpm_list. This causes the gpio-tegra device to be suspended before gpio-keys, which in turn leaves gpio-keys unable to wake the system from suspend. There are patches in the works to fix both of the above issues, but they are too involved to make it into v4.3, so in the meantime let's fix the regressions by commenting out the gpio-ranges properties until the fixes have landed.

Normally hci_conn_del is the right thing to do, but in the case of a connection doing LE scanning this could cause a deadlock due to doing a cancel_delayed_work_sync() on the same work callback that we were called from. Connections in the LE scanning state actually need very little cleanup - just a small subset of hci_conn_del. To solve the issue, refactor out these essential pieces into a new hci_conn_cleanup() function and call that from the two necessary places.

Not using it in turn means leaving out entries in pend_le_reports. To fix this and simplify the logic move conn params from the reports list to the pend_le_conns list for the duration of an explicit connect. Once the connect is complete move the params back to the pend_le_reports list. This also means that the explicit connect lookup function only needs to look into the pend_le_conns list.

For PAE kernels the identity mapping is achieved by aliasing the first PDPE for the kernel memory mapping into the first PDPE of initial_page_table. This makes the EFI stub's trick "just work". However, for non-PAE kernels there is no guarantee that the identity mapping in the initial_page_table extends as far as the GDT; in this case, accesses to the GDT will cause a page fault (which quickly becomes a triple fault). Fix this by copying the kernel mappings from swapper_pg_dir to initial_page_table twice, both at PAGE_OFFSET and at identity mapping. For some reason, this is only reproducible with QEMU's dynamic translation mode, and not for example with KVM. However, even under KVM one can clearly see that the page table is bogus: $ qemu-system-i386 -pflash OVMF.fd -M q35 vmlinuz0 -s -S -daemonize $ gdb (gdb) target remote localhost:1234 (gdb) hb *0x02858f6f Hardware assisted breakpoint 1 at 0x2858f6f (gdb) c Continuing.

Andy Lutomirski provides some additional insight: "AFAICT it's entirely permissible for the GDTR and/or LDT descriptor to point to unmapped memory. Any attempt to use them (segment loads, interrupts, IRET, etc) will try to access that memory as if the access came from CPL 0 and, if the access fails, will generate a valid page fault with CR2 pointing into the GDT or LDT." Up until commit 23a0d4e8fa6d ("efi: Disable interrupts around EFI calls, not in the epilog/prolog calls") interrupts were disabled around the prolog and epilog calls, and the functional GDT was re-installed before interrupts were re-enabled. Which explains why no one has hit this issue until now. ] Signed-off-by: Paolo Bonzini Reported-by: Laszlo Ersek Cc: Cc: Borislav Petkov Cc: "H.

Currently every CODEC implementing these controls specifies the minimum as the non-zero value for the minimum and the maximum as the number of gain settings available. This means when the info callback subtracts the minimum value from the maximum value to calculate the number of gain levels available it is actually under reporting the available levels.

Testing showed that setting XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT quirk allowed the system to shutdown as expected for LynxPoint-LP xHCI controllers. Set the quirk back. Note that the quirk was originally introduced for LynxPoint and LynxPoint-LP just for this same reason. See: commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell") It was later limited to only concern HP machines as it caused regression on some machines, see both bug and commit: Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171 commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP machines") Later it was discovered that the powering on after shutdown was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP machine suffered from spontaneous resume from S3 (which should not be related to the SPURIOUS_WAKEUP quirk at all). An attempt to fix this then removed the SPURIOUS_WAKEUP flag usage completely. commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell") Current understanding is that LynxPoint-LP (Haswell ULT) machines need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and plain Lynxpoint (Haswell) machines may _not_ have the quirk set otherwise they again will restart.

It is capped at 16KiB. The intention is to avoid small allocations and to minimize the number of calls required to obtain dump information for all net devices. netlink_dump packs as many small messages as could fit within an skb that was sized for the largest single netdev information. The actual space available within an skb is larger than what is requested. It could be much larger and up to near 2x with align to next power of 2 approach. Allowing netlink_dump to use all the space available within the allocated skb increases the buffer size a user has to provide to avoid truncaion (i.e. MSG_TRUNG flag set). It was observed that with many VLANs configured on at least one netdev, a larger buffer of near 64KiB was necessary to avoid "Message truncated" error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when min_alloc_size was only little over 32KiB. This patch trims skb to allocated size in order to allow the user to avoid truncation with more reasonable buffer size. Signed-off-by: Ronen Arad Signed-off-by: David S.

Before lightweight tunnels existed, it really didn't make sense to create a tunnel that was not fully specified, such as without a destination IP address - the resulting packets would go nowhere. However, with lightweight tunnels, the opposite is true - it doesn't make sense to require this information when it will be provided later on by the route. This loosens the requirements for this information. An alternative would be to allow the relaxed version only when COLLECT_METADATA is enabled. However, since there are several variations on this theme (such as NBMA tunnels in GRE), just dropping the restrictions seems the most consistent across tunnels and with the existing configuration.

That patch reduced the SIPI delays from udelay() 300, 200 to udelay() 0, 0 on modern processors. Several Intel(R) Core(TM)2 systems failed to bring up CPU #1 10/10 times after that change. Increasing either of the SIPI delays to udelay(1) results in success. So here we increase both to udelay(10).

The bad case can be easily reproduced when a number of CPU hogs compete for the CPUs at the same time (thanks to Mike). This is largly because the task group's load average tracking cross CPUs lags behind the real changes. To fix this we accelerate the group share distribution process by using the load.weight of the cfs_rq. This may increase the entire group's share, but we have to do so to protect the (fragile) interactive tasks, especially from CPU hogs.

This means that tasks run by default on CPUs outside the nohz_full range unless their affinity is explicity overwritten. This suits pure isolation workloads but when the machine is needed to run common workloads, the available sets of CPUs to run common tasks becomes reduced. We reach an extreme case when CONFIG_NO_HZ_FULL_ALL is enabled as it leaves only CPU 0 for non-isolation tasks, which makes people think that their supercomputer regressed to 90's UP - which is true in a sense. Some full-nohz users appear to be interested in running normal workloads either before or after an isolation workload. Full-nohz isn't optimized toward normal workloads but it's still better than UP performance. We are reaching a limitation in kernel presets here. Lets revert this cpu_isolated_map inclusion and let userspace do its own scheduler isolation using cpusets or explicit affinity settings.

However, if the remote runqueue does not contain any SCHED_DEADLINE task its earliest_dl.curr is 0 (always smaller than the deadline of the local task) and the remote runqueue is not selected for pushing. As a result, if an application creates multiple SCHED_DEADLINE threads, they will never be pushed to runqueues that do not already contain SCHED_DEADLINE tasks.

KASAN will not check the memory accessed by READ_ONCE_NOCHECK(). The KernelThreadSanitizer (KTSAN) is going to ignore it as well. This patch creates __read_once_size_nocheck() a clone of __read_once_size(). The only difference between them is 'no_sanitized_address' attribute appended to '*_nocheck' function. This attribute tells the compiler that instrumentation of memory accesses should not be applied to that function.

Some of these functions are called after RCU had already stopped watching, as RCU does not watch userspace or idle CPUs. If a max stack is hit, then the save_stack_trace() is called, which will check module addresses and call module_assert_mutex_or_preempt(), and then trigger the warning. Sad part is, the warning itself will also do a stack trace and tigger the same warning. That probably should be fixed. The warning was added by 0be964be0d45 "module: Sanitize RCU usage and locking" but this bug has probably been around longer. But it's unlikely to cause much harm, but the new warning causes the system to lock up. Cc: stable@vger.kernel.org # 4.2+ Cc: Peter Zijlstra Cc:"Paul E.

The problem is that because the guest disables the virtual interrupt at the VGIC level, we never inject interrupts to the guest and therefore never mark the interrupt as active on the physical distributor. The host also never takes the timer interrupt (we only use the timer device to trigger a guest exit and everything else is done in software), so the interrupt does not become active through normal means. The result is that we keep entering the guest with a programmed timer that will always fire as soon as we context switch the hardware timer state and run the guest, preventing forward progress for the VCPU. Since the active state on the physical distributor is really part of the timer logic, it is the job of our virtual arch timer driver to manage this state. The timer->map->active boolean field indicates whether we have signalled this interrupt to the vgic and if that interrupt is still pending or active. As long as that is the case, the hardware doesn't have to generate physical interrupts and therefore we mark the interrupt as active on the physical distributor. We also have to restore the pending state of an interrupt that was queued to an LR but was retired from the LR for some reason, while remaining pending in the LR.

However, since the architected timers are defined by the architecture to be level triggered and the guest rightfully expects them to be that, but we emulate them as edge-triggered, we have to mimic level-triggered behavior for an edge-triggered virtual implementation. We currently do not signal the VGIC when the map->active field is true, because it indicates that the guest has already been signalled of the interrupt as required. Normally this field is set to false when the guest deactivates the virtual interrupt through the sync path. We also need to catch the case where the guest deactivates the interrupt through the emulated distributor, again allowing guests to boot even if the original virtual timer signal hit before the guest's GIC initialization sequence is run.

This is incorrect, because updating the state does not consider the distributor enable bit, and this you can end up in a situation where an interrupt is marked as pending on the CPU interface, but not pending on the distributor, which is an impossible state to be in, and triggers a warning. Consider for example the following sequence of events: 1. An interrupt is marked as pending on the distributor - the interrupt is also forwarded to the CPU interface 2. The guest turns off the distributor (it's about to do a reboot) - we stop updating the CPU interface state from now on 3. The guest disables the pending interrupt - we remove the pending state from the distributor, but don't touch the CPU interface, see point 2. Since the distributor disable bit really means that no interrupts should be forwarded to the CPU interface, we modify the code to keep updating the internal VGIC state, but always set the CPU interface pending bits to zero when the distributor is disabled.

In fact the logmpp instruction was incorrectly using register r0 as the source of the buffer address and operation code, and depending on what was in r0, it would either do nothing or corrupt the 64k page pointed to by r0. The logmpp instruction encoding and the operation code definitions could be corrected, but then there is the problem that there is no clearly defined way to know when the hardware has finished writing to the buffer. The original commit attempted to work around this by aborting the write-out before starting the prefetch, but this is ineffective in the case where the virtual core is now executing on a different physical core from the one where the write-out was initiated. These problems plus advice from the hardware designers not to use the function (since the measured performance improvement from using the feature was actually mostly negative), mean that reverting the code is the best option.

What can happen is that a maskable interrupt of some kind (external, decrementer, hypervisor doorbell, or HMI) after we have called local_irq_disable() at the beginning of pnv_smp_cpu_kill_self() and before interrupts are hard-disabled inside power7_nap/sleep/winkle(). In this situation, the pending event is marked in the irq_happened flag in the PACA. This pending event prevents power7_nap/sleep/winkle from going to the requested low-power state; instead they return immediately. We don't deal with any of these pending event flags in the off-line loop in pnv_smp_cpu_kill_self() because power7_nap et al. return 0 in this case, so we will have srr1 == 0, and none of the processing to clear interrupts or doorbells will be done. Usually, the most obvious symptom of this is that a KVM guest will fail with a console message saying "KVM: couldn't grab cpu N". This fixes the problem by making sure we handle the irq_happened flags properly. First, we hard-disable before the off-line loop. Once we have hard-disabled, the irq_happened flags can't change underneath us. We unconditionally clear the DEC and HMI flags: there is no processing of timer interrupts while off-line, and the necessary HMI processing is all done in lower-level code. We leave the EE and DBELL flags alone for the first iteration of the loop, so that we won't fail to respond to a split-core request that came in just before hard-disabling. Within the loop, we handle external interrupts if the EE bit is set in irq_happened as well as if the low-power state was interrupted by an external interrupt. (We don't need to do the msgclr for a pending doorbell in irq_happened, because doorbells are edge-triggered and don't remain pending in hardware.) Then we clear both the EE and DBELL flags, and once clear, they cannot be set again (until this CPU comes online again, that is). This also fixes the debug check to not be done when we just ran a KVM guest or when the sleep didn't happen because of a pending event in irq_happened.

Redo rbd_dev_probe_parent() to fix this.

User can set the HWEQ parameters using the ALSA binary control byte-by-byte. We use the following struct array to store the HWEQ parameters for implementing as simple as possible. struct rt5645_eq_param_s { unsigned short reg; unsigned short val; }; It supports the variant length of the HWEQ parameters that are required. We add the validating function in the function "rt5645_hweq_put" of the ALSA binary control to avoid the user that puts the invalid parameters. In the HWEQ enable function of speaker event, we also add the validating function to prevent that the invalid parameters are applied to codec. The HWEQ parameters should be controlled by DAPM for a specific sequence, so the parameters will be applied to the codec in the speaker power up event of DAPM, and will be disabled in the speaker power down event of DAPM.

Fix this issue, of the cache's on-disk flags being wrong, by making sure __commit_transaction() does not reset the flags after the mutator has altered the flags in preparation for them being serialized to disk. before: sb_flags = mutator(le32_to_cpu(disk_super->flags)); disk_super->flags = cpu_to_le32(sb_flags); disk_super->flags = cpu_to_le32(cmd->flags); after: disk_super->flags = cpu_to_le32(cmd->flags); sb_flags = mutator(le32_to_cpu(disk_super->flags)); disk_super->flags = cpu_to_le32(sb_flags); Reported-by: Bogdan Vasiliev Signed-off-by: Joe Thornber Signed-off-by: Mike Snitzer Cc: stable@vger.kernel.org --- drivers/md/dm-cache-metadata.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/md/dm-cache-metadata.c b/drivers/md/dm-cache-metadata.c index 20cc36b..0a17d1b 100644 --- a/drivers/md/dm-cache-metadata.c +++ b/drivers/md/dm-cache-metadata.c @@ -634,10 +634,10 @@ static int __commit_transaction(struct dm_cache_metadata *cmd, disk_super = dm_block_data(sblock); + disk_super->flags = cpu_to_le32(cmd->flags); if (mutator) update_flags(disk_super, mutator); - disk_super->flags = cpu_to_le32(cmd->flags); disk_super->mapping_root = cpu_to_le64(cmd->root); disk_super->hint_root = cpu_to_le64(cmd->hint_root); disk_super->discard_root = cpu_to_le64(cmd->discard_root); -- cgit v1.1 From ab57b8e90c658a72944c48a81a1352e61e84db02 Mon Sep 17 00:00:00 2001 From: Maruthi Srinivas Bayyavarapu Date: Fri, 23 Oct 2015 17:15:41 -0400 Subject: ASoC: dwc: add check for master/slave format DW i2s controller's master/slave config can be read from a read-only register.
