This reverts commit cfecde435dda78248d6fcdc424bed68d5db6be0b. The commit was first created as an attempt to fix LVDS initialiazation on Ironlake. Testing revealed that it didn't fix that, but it was assumed to still be correct anyway. Subsequent testing has revealed that this commit has caused other regressions: * Change in VBlank interrupt frequency causing 60% 3D performance regression http://bugs.freedesktop.org/show_bug.cgi?id=27698 * Black screen on G45 http://bugs.freedesktop.org/show_bug.cgi?id=27733 So revert this buggy code for now to revisit later when we can fix actual bugs without causing these regressions.

The old way (sources, enable, unmask) gives a window during which interrupt conditions would appear in ISR but would never reach IIR and thus never raise an IRQ. Since interrupts only trigger on rising edges in ISR, this would lead to conditions where (for example) output hotplugging would never fire an interrupt because it was already stuck on in ISR. Also, since we know IIR and PIPExSTAT have been cleared during irq_preinstall, don't clear them again during irq_postinstall, nothing good can come of that.

Maxim Levitsky discovered that this could be rectified by forcibly saving and restoring the ACPI non-volatile state. The spec indicates that this is only required for S4, but testing the behaviour of Windows by adding an ACPI NVS region to qemu's e820 map and registering a custom memory read/write handler reveals that it's saved and restored even over suspend to RAM. We should mimic that behaviour to avoid other broken platforms.

First, the GPE disabled by it is never enabled again (except during resume) which leads to battery insert/remove events not being reported on the Maxim Levitsky's machine. Second, the disabled GPE is still reported as enabled by the sysfs interface that only checks its enable register's enable_for_run mask.

Wysocki" Date: Tue, 8 Jun 2010 10:49:08 +0200 Subject: ACPI / ACPICA: Fix low-level GPE manipulation code ACPICA uses acpi_ev_enable_gpe() for enabling GPEs at the low level, which is incorrect, because this function only enables the GPE if the corresponding bit in its enable register's enable_for_run mask is set. This causes acpi_set_gpe() to work incorrectly if used for enabling GPEs that were not previously enabled with acpi_enable_gpe(). As a result, among other things, wakeup-only GPEs are never enabled by acpi_enable_wakeup_device(), so the devices that use them are unable to wake up the system. To fix this issue remove acpi_ev_enable_gpe() and its counterpart acpi_ev_disable_gpe() and replace acpi_hw_low_disable_gpe() with acpi_hw_low_set_gpe() that will be used instead to manipulate GPE enable bits at the low level. Make the users of acpi_ev_enable_gpe() and acpi_ev_disable_gpe() call acpi_hw_low_set_gpe() instead and make sure that GPE enable masks are only updated by acpi_enable_gpe() and acpi_disable_gpe() when GPE reference counters change from 0 to 1 and from 1 to 0, respectively.

Wysocki" Date: Tue, 8 Jun 2010 10:49:45 +0200 Subject: ACPI / ACPICA: Avoid writing full enable masks to GPE registers ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after an event signaled by it has been handled. However, this function writes the entire GPE enable mask to the GPE's enable register which may not be correct. Namely, if one of the other GPEs in the same register was previously enabled by acpi_enable_gpe() and subsequently disabled using acpi_set_gpe(), acpi_hw_write_gpe_enable_reg() will re-enable it along with the target GPE. To fix this issue rework acpi_hw_write_gpe_enable_reg() so that it calls acpi_hw_low_set_gpe() with a special action value, ACPI_GPE_COND_ENABLE, that will make it only enable the GPE if the corresponding bit in its register's enable_for_run mask is set.

Some might not like the fact that LRO was disabled automatically, but I'm fine with that. What I don't like is that LRO/RSC is automatically enabled when rx-usecs is set >0 via ethtool. This would certainly be a problem if the device was used for forwarding and it was determined that the low latency wasn't needed after the device was already forwarding. I played around with saving the state of LRO in the driver, but it just didn't seem worthwhile and would require a small change to dev_disable_lro() that I did not like. This patch simply leaves LRO disabled when setting rx-usecs >0 and requires that the user enable it again. An extra informational message will also now appear in the log so users can understand why LRO isn't being enabled as they expect. Inconsistency of LRO setting first noticed by Stanislaw Gruszka.

Examining the code, I found that this problem occures when an OMAP1 internal LCD controller is disabled from omap_lcdc_suspend() and then a subsequent omap_lcdc_setup_plane() calls disable_controller() again. This potentially error provoking behaviour is triggered by the lcdc.update_mode flag being kept at OMAP_AUTO_UPDATE, regardless of the controller and panel being suspended. This patch tries to correct the problem by replacing both omap_lcdc_suspend() and omap_lcdc_resume() function bodies with single calls to omap_lcdc_set_update_mode() with a respective OMAP_UPDATE_DISABLE or OMAP_AUTO_UPDATE argument. As a result, exactly the same lower level operations are performed, with addition of changing the lcdc.update_mode flag to a value better suited for the controller state. This prevents any further calls to disable_controller() from omap_lcdc_setup_plane() while the display is suspended. Created against linux-2.6.34-rc7. Tested on Amstrad Delta.

However, if the RCTRL_TS_ENABLE is set without TMR_CTRL[TE], the driver does not work properly on some boards (Anton had problems with the MPC8313ERDB and MPC8568EMDS). With this patch the bit will only be set if requested from user space with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is disabled during normal operation. Users who are not interested in time stamps will not experience problems with buggy CPU revisions or performance drops any more. The setting of TMR_CTRL[TE] is still up to the user. This is considered safe because users wanting HW timestamps must initialize the eTSEC clock first anyway, e.g. with the recently submitted PTP clock driver.

Unfortunately, this leads to a regression reported by Michal Hocko, where a system is woken up from ACPI S5 by a device that is not supposed to do that, because the wakeup enable mask bit of this device's GPE is always set when acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(), although it should only be set if the device is supposed to wake up the system from the target state. To work around this issue, rework the ACPI power management code so that GPEs are not enabled to wake up the system upfront, but only during a system state transition when the target state of the system is known. [Of course, this means that the reference counting of "wakeup" GPEs doesn't really make sense and it is sufficient to set/unset the wakeup mask bits for them during system sleep transitions. This will allow us to simplify the GPE handling code quite a bit, but that change is too intrusive for 2.6.35.] Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15951 Signed-off-by: Rafael J.

However, the native PCIe PME is coupled to the native PCIe hotplug and calling pcie_pme_acpi_setup() makes some BIOSes expect that the native PCIe hotplug will be used as well. That, in turn, causes problems to appear on systems where the PCIe hotplug driver is not loaded. The usual symptom, as reported by Jaroslav Kameník and others, is that the ACPI GPE associated with PCIe hotplug keeps firing continuously causing kacpid to take substantial percentage of CPU time. To work around this issue, change the default so that the native PCIe PME signaling is only used if directly requested with the help of the pcie_pme= command line switch.

I recently had a report about a Sempron 3200+, model 95, for which this patch broke temperature reading. It happens that this is a single-core processor, so the effect of the swapping was to read a temperature value for a core that didn't exist, leading to an incorrect value (-49 degrees C.) Disabling core swapping on singe-core processors should fix this. Additional comment from Andreas: The BKDG says Thermal Sensor Core Select (ThermSenseCoreSel)-Bit 2. This bit selects the CPU whose temperature is reported in the CurTemp field. This bit only applies to dual core processors. For single core processors CPU0 Thermal Sensor is always selected. k8temp_probe() correctly detected that SEL_CORE can't be used on single core CPU. Thus k8temp did never update the temperature values stored in temp[1][x] and -49 degrees was reported. For single core CPUs we must use the values read into temp[0][x].

This might lead to a case where ani timer would be left undeleted and cause improper memory acccess during module unload. This bug is clearly exposed with paprd support where the driver detects tx hang and does a chip reset. During this reset ani is (re)started without checking if it needs to be started. This would leave a timer scheduled even after all the resources are freed and cause a panic. This patch introduces a bit in sc_flags to indicate if ani needs to be started in sw_scan_start() and ath_reset(). This would fix the following panic. This issue is easily seen with ar9003 + paprd.

Commit b821eaa572fd737faaf6928ba046e571526c36c6 broke partition detection for md arrays. The logic was almost right. However if revalidate_disk is called when the device is not yet open, bdev->bd_disk won't be set, so the flush_disk() Call will not set bd_invalidated. So when md_open is called we still need to ensure that ->bd_invalidated gets set. This is easily done with a call to check_disk_size_change in the place where the offending commit removed check_disk_change. At the important times, the size will have changed from 0 to non-zero, so check_disk_size_change will set bd_invalidated.

Most array level changes leave the list of devices largely unchanged, possibly causing one at the end to become redundant. However conversions between RAID0 and RAID10 need to renumber all devices (except 0). This renumbering is currently being done in the ->run method when the new personality takes over. However this is too late as the common code in md.c might already have invalidated some of the devices if they had a ->raid_disk number that appeared to high. Moving it into the ->takeover method is too early as the array is still active at that time and wrong ->raid_disk numbers could cause confusion. So add a ->new_raid_disk field to mdk_rdev_s and use it to communicate the new raid_disk number. Now the common code knows exactly which devices need to be renumbered, and which can be invalidated, and can do it all at a convenient time when the array is suspend. It can also update some symlinks in sysfs which previously were not be updated correctly.

When an array is reshaped to have fewer devices, the reshape proceeds from the end of the devices to the beginning. If a device happens to be non-In_sync (which is possible but rare) we would normally update the ->recovery_offset as the reshape progresses. However that would be wrong as the recover_offset records that the early part of the device is in_sync, while in fact it would only be the later part that is in_sync, and in any case the offset number would be measured from the wrong end of the device. Relatedly, if after a reshape a spare is discovered to not be recoverred all the way to the end, not allow spare_active to incorporate it in the array. This becomes relevant in the following sample scenario: A 4 drive RAID5 is converted to a 6 drive RAID6 in a combined operation. The RAID5->RAID6 conversion will cause a 5 drive to be included as a spare, then the 5drive -> 6drive reshape will effectively rebuild that spare as it progresses. The 6th drive is treated as in_sync the whole time as there is never any case that we might consider reading from it, but must not because there is no valid data. If we interrupt this reshape part-way through and reverse it to return to a 5-drive RAID6 (or event a 4-drive RAID5), we don't want to update the recovery_offset - as that would be wrong - and we don't want to include that spare as active in the 5-drive RAID6 when the reversed reshape completed and it will be mostly out-of-sync still.

When we are reshaping an array, the device failure combinations that cause us to decide that the array as failed are more subtle. In particular, any 'spare' will be fully in-sync in the section of the array that has already been reshaped, thus failures that affect only that section are less critical. So encode this subtlety in a new function and call it as appropriate. The case that showed this problem was a 4 drive RAID5 to 8 drive RAID6 conversion where the last two devices failed. This resulted in: good good good good incomplete good good failed failed while converting a 5-drive RAID6 to 8 drive RAID5 The incomplete device causes the whole array to look bad, bad as it was actually good for the section that had been converted to 8-drives, all the data was actually safe.

As the comment says, the tail of this loop only applies to devices that are not fully in sync, so if In_sync was set, we should avoid the rest of the loop. This bug will hardly ever cause an actual problem. The worst it can do is allow an array to be assembled that is dirty and degraded, which is not generally a good idea (without warning the sysadmin first). This will only happen if the array is RAID4 or a RAID5/6 in an intermediate state during a reshape and so has one drive that is all 'parity' - no data - while some other device has failed. This is certainly possible, but not at all common.

There are few situations where it would make any sense to add a spare when reducing the number of devices in an array, but it is conceivable: A 6 drive RAID6 with two missing devices could be reshaped to a 5 drive RAID6, and a spare could become available just in time for the reshape, but not early enough to have been recovered first. 'freezing' recovery can make this easy to do without any races. However doing such a thing is a bad idea. md will not record the partially-recovered state of the 'spare' and when the reshape finished it will think that the spare is still spare. Easiest way to avoid this confusion is to simply disallow it.

The reason, it turns out, is that the code previously checked if ALLMULTI _changed_, which the new code no longer did, and normally it _never_ changes. Had somebody changed it manually, the code prior to my patch there would have been broken already. The reason is that we always, unconditionally, ask the device to pass up all multicast frames, but the new code made it depend on ALLMULTI which broke it since now we'd pass up multicast frames depending on the default filter in the device, which isn't necessarily what we want (since we don't program it right now). Fix this by simply not checking allmulti as we have allmulti behaviour enabled already anyway.

Simple actions like changing the active slave in active-backup mode will hang the box if a high enough printk debugging level is enabled. Keeping the old code around will be good for anyone that wants to work on it (and for after the RCU conversion), so I propose this small patch rather than ripping it all out.

Instead of checking the hour register it reads the minute register. Therefore the driver thinks minutes >= 40 has the 12HR bit set and resets the minute register by zeroing the high bits. This results in minutes are reset to 0-9, jumping back in time 40 or 50 minutes. The time jump is also written back to the RTC.

Commit 6c12db90f19727c76990e7f4801c67a148b30111 introduced a bug for control transfers. The patch was supposed to change when the link TRBs at the end of each ring segment were given to the hardware. If a transfer descriptor (TD) ended just before the link TRB, the code wouldn't give back the link TRB to the hardware; instead it would be given back in prepare_ring() just before the next TD was enqueued at the top of the ring. Unfortunately, the code relied on checking the chain bit of the TRB to determine whether the TD ended just before the link TRB. It assumed that the ring enqueuing code would call prepare_ring() before enqueuing the next TD. However, control transfers are made of multiple TDs, and prepare_ring() is only called once before enqueuing two or three TDs. If the first or second TD of the control transfer ended just before the link TRB, then the code in inc_enq() would not move the enqueue pointer past the link TRB, and the link TRB would get overwritten. This would cause the xHCI driver to start writing to memory past the ring segment, and eventually the system would crash or hang. The fix is to add a flag to inc_enq() that says whether the caller will enqueue more TDs before calling prepare_ring(). If the chain bit is cleared (meaning this is the last TRB in a TD), and the caller will not enqueue more TDs, then we defer giving back the link TRB.

After hearing from a user, I realized that remote wakeup should be enabled during system sleep whenever userspace allows it, and not only if a driver requests it too. Indeed, there could be a device with no driver, that does nothing but generate a wakeup request when the user presses a button. Such a device should be allowed to do its job. The problem fixed by the earlier patch -- device generating a wakeup request for no reason, causing system suspend to abort -- was also addressed by a later patch ("USB: don't enable remote wakeup by default", accepted but not yet merged into mainline). The device won't be able to generate the bogus wakeup requests because it will be disabled for remote wakeup by default. Hence this reversion will not re-introduce any old problems.

As an effect, the incorrect pointer was preserved in all further operations which caused do_set_interface to reference an invalid region. This commit fixes this by raising an exception in fsg_bind which will change the common->fsg pointer. This also requires an wait queue so that the thread in fsg_bind can wait till the worker thread handles the exception. This commit removes also a config and new_config fields of fsg_common as they are no longer needed since fsg can be used to determine whether function is active or not. Moreover, this commit removes possible race condition where the fsg field was modified in both the worker thread and form various other contexts. This is fixed by replacing prev_fsg with new_fsg. At this point, fsg is assigned only in worker thread.

This seems to be down to the incorrect setting of dev_private->scan_delay in pci9111_ai_do_cmd(). Under the previously stated conditions, dev_private->scan_delay ends up set to (unsigned int)-1, but it ought to be set to 0. The function sets it to 0 initially, and it only makes sense to change it if both convert_src and scan_begin_src are set to TRIG_TIMER. Note: 'scan_delay' is the number of unwanted scans to discard after each valid scan. The hardware does not support 'scan' timing as such, just a regularly paced conversion timer (with automatic channel switching between conversions). The driver simulates a scan period that is some (>1) multiple of the conversion period times the scan length (chanlist_len samples) by reading chanlist_len samples and discarding the next scan_delay times chanlist_len samples.

What happens? In the ALB mode, bonding driver keeps track of each client connected in a hash table, so it can do the receive load balancing (RLB). This hash table is updated when an ARP reply is received, then it scans for the client entry, updates its MAC address and flag it to be announced later. Therefore, two seconds later, the alb monitor runs and send for each updated client entry two ARP replies updating this specific client. The same process happens on the receiving system, causing the endless ping-pong of arp replies. See more information including the relevant functions below: System 1 System 2 bond0 bond0 ping ARP request ---------> <--------- ARP reply +->rlb_arp_recv <---------------------+ <--- loop begins | rlb_update_entry_from_arp | | client_info->ntt = 1; | | bond_info->rx_ntt = 1; | | | | | | | | bond_alb_monitor | | rlb_update_rx_clients | | rlb_update_client | | arp_create(ARPOP_REPLY) | | send ARP reply --------------> V | send ARP reply --------------> | rlb_arp_recv | rlb_update_entry_from_arp | client_info->ntt = 1; | bond_info->rx_ntt = 1; | < snipped, same as in system 1> +------- <-------------- send ARP reply <-------------- send ARP reply Besides the unneeded networking traffic, this loop breaks a cluster because a backup system can't take over the IP address. There is always one system sending an ARP reply poisoning the network. This patch fixes the problem adding a check for the MAC address before updating it. Thus, if the MAC address didn't change, there is no need to update neither to announce it later. Signed-off-by: Flavio Leitner Signed-off-by: Jay Vosburgh Signed-off-by: David S.

Wysocki" Date: Thu, 17 Jun 2010 23:02:27 +0000 Subject: DRM / radeon / KMS: Fix hibernation regression related to radeon PM (was: Re: [Regression, post-2.6.34] Hibernation broken on machines with radeon/KMS and r300) There is a regression from 2.6.34 related to the recent radeon power management changes, caused by attempting to cancel a delayed work item that's never been scheduled. However, the code as is has some other issues potentially leading to visible problems. First, the mutex around cancel_delayed_work() in radeon_pm_suspend() doesn't really serve any purpose, because cancel_delayed_work() only tries to delete the work's timer. Moreover, it doesn't prevent the work handler from running, so the handler can do some wrong things if it wins the race and in that case it will rearm itself to do some more wrong things going forward. So, I think it's better to wait for the handler to return in case it's already been queued up for execution. Also, it should be prevented from rearming itself in that case. Second, in radeon_set_pm_method() the cancel_delayed_work() is not sufficient to prevent the work handler from running and queing up itself for the next run (the failure scenario is that cancel_delayed_work() returns 0, so the handler is run, it waits on the mutex and then rearms itself after the mutex has been released), so again the work handler should be prevented from rearming itself in that case.. Finally, there's a potential deadlock in radeon_pm_fini(), because cancel_delayed_work_sync() is called under rdev->pm.mutex, but the work handler tries to acquire the same mutex (if it wins the race). Fix the issues described above. Signed-off-by: Rafael J.

First, it did not, in fact, disable the CRT plug interrupt -- it disabled all the other hotplug interrupts. It seems rather doubtful that that bit of the patch fixed anything, so let's just remove it. (If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.) Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64 and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset) causes a hotplug interrupt about three seconds later.

The flow for this is, dev_queue_xmit() dev_pick_tx() skb_tx_hash() => hash using real_num_tx_queues skb_set_queue_mapping() ... qdisc_enqueue_root() => enqueue skb on txq from hash ... dev->real_num_tx_queues -= n ... sch_direct_xmit() dev_hard_start_xmit() ndo_start_xmit(skb,dev) => skb queue set with old hash skbs are enqueued on the qdisc with skb->queue_mapping set 0 < queue_mappings < real_num_tx_queues. When the driver decreases real_num_tx_queues skb's may be dequeued from the qdisc with a queue_mapping greater then real_num_tx_queues. This fixes a case in ixgbe where this was occurring with DCB and FCoE. Because the driver is using queue_mapping to map skbs to tx descriptor rings we can potentially map skbs to rings that no longer exist.

On Xframe adapters, the received multicast statistics counter includes pause frames which are not indicated to the driver. This can cause issues where the multicast packet count is higher than what has actually been received, possibly higher than the number of packets received. The driver software counters are replaced with the adapter hardware statistics for rx_packets, rx_bytes, and tx_bytes. It also uses the overflow registers to determine if the statistics wrapped the 32bit register (removing the window of having a statistic value less than the previous call). rx_length_errors statistic now includes undersized packets in addition to oversized packets in its counting. Finally, rx_crc_errors are now being counted. Signed-off-by: Jon Mason Signed-off-by: David S.

For RDMA CQs, however, returning CIDX_INC credits is only needed and desired when and if the CQ is armed for notification. This can lead to a GTS write returning credits that causes the HW to reject the credit update because it causes CIDX to pass PIDX. Once this happens, the CIDX/PIDX counters get out of whack and an application can miss a notification and get stuck blocked awaiting a notification. To avoid this, we allocate the HW IQ 2x times the requested size. This seems to avoid the false overflow failures. If we see more issues with this, then we'll have to add code in the poll path to return credits periodically like when the amount reaches 1/2 the queue depth).

Repeated ttm_page_alloc_init/fini fails noisily because the pool manager kobj isn't zeroed out between uses (we could do just that but statically allocated kobjects are generally considered a bad thing). Move it to kzalloc'ed memory. Note that this patch drops the refcounting behavior of the pool allocator init/fini functions: it would have led to a race condition in its current form, and anyway it was never exploited. This fixes a regression with reloading kms modules at runtime, since page allocator was introduced.

Curiously, there still is a configuration bit to control this, which means it can be set incorrectly. And even more curiously, many boards out there are improperly configured, even though the IT8720F datasheet claims that the internal routing of VCCH to VIN7 is the default setting.

Linux tries to make sure all PCI device BARs are inside the upstream PCI host bridge or P2P bridge apertures, reassigning BARs if necessary. Windows does similar reassignment. Before this patch, if we could not move a BAR into an aperture, we left the resource unassigned, i.e., at address zero. Windows leaves such BARs at the original BIOS addresses, and this patch makes Linux do the same. This is a bit ugly because we disable the resource long before we try to reassign it, so we have to keep track of the BIOS BAR address somewhere. For lack of a better place, I put it in the struct pci_dev. I think it would be cleaner to attempt the assignment immediately when the claim fails, so we could easily remember the original address. But we currently claim motherboard resources in the middle, after attempting to claim PCI resources and before assigning new PCI resources, and changing that is a fairly big job.

Vefa Bicakci tested lots of hibernate cycles, and without the __GFP_RECLAIMABLE flag the system eventually fails to resume. With the flag added, Vefa can apparently hibernate forever (or until he gets bored running his automated scripts, whichever comes first). The reclaimable flag was there originally, and was one of the flags that were dropped (unintentionally) by commit 4bdadb978569 ("drm/i915: Selectively enable self-reclaim") that introduced all these problems, but I didn't want to just blindly add back all the flags in commit 985b823b9192, and it looked like __GFP_RECLAIM wasn't necessary. It clearly was. I still suspect that there is some subtle reason we're missing that causes the problems, but __GFP_RECLAIMABLE is certainly not wrong to use in this context, and is what the code historically used. And we have no idea what the causes the corruption without it. Reported-and-tested-by: M.

You generally have two cases where DDC lines are shared: - HDMI + VGA - HDMI + DVI-D HDMI + VGA is easy to deal with because you can check the EDID for the to see if the attached monitor is digital. A shared DDC line with two digital connectors is more complex. You can't use the hdmi bits in the EDID since they may not be there with DVI<->HDMI adapters. In this case all we can do is check the HPD pins to see which is connected as we have no way of knowing using the EDID.

The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory.
