From 7ec01ff950c455aa1f1ccfaf347eb1aa9ec160d5 Mon Sep 17 00:00:00 2001 From: Ralph Campbell Date: Fri, 15 Aug 2008 11:23:47 -0700 Subject: IB/ipath: Fix lost UD send work request If a UD QP has some work requests queued to be sent by the DMA engine followed by a local loopback work request, we have to wait for the previous work requests to finish or the completion for the local loopback work request would be generated out of order. The problem was that the work request queue pointer was already updated so that the request would not be processed when the DMA queue drained.

However, ipoib_stop() (which is run inside rtnl_lock()) flushes this workqueue, which leads to a deadlock if the join task is pending. Fix this by simply not flushing the workqueue from ipoib_stop(). It turns out that we really don't care about workqueue tasks running during or after ipoib_stop(), as long as we make sure to flush the workqueue before unregistering a netdev. This fixes .

The new dev->power.status field should be initialized regardless of whether CONFIG_PM_SLEEP is enabled, and similarly dpm_sysfs_add() should be called whenever CONFIG_PM is enabled. The patch separates out the call to dpm_sysfs_add() from the call to device_pm_add(). As a result device_pm_add() can no longer return an error, so its return type is changed to void.

This driver is very similar to the regular UIO platform driver, but is only suitable for devices that are connected to the interrupt controller using unique interrupt lines. The uio_pdrv_genirq driver includes generic interrupt handling code which disables the serviced interrupt in the interrupt controller and makes the user space driver responsible for acknowledging the interrupt in the device and reenabling the interrupt in the interrupt controller. Shared interrupts are not supported since the in-kernel interrupt handler will disable the interrupt line in the interrupt controller, and in a shared interrupt configuration this will stop other devices from delivering interrupts.

When control returns to this ep0_rxstate, the index register contents are over-written. This causes the CSR register write to fail. Fixed by writing the correct value into the index register before writing to the CSR. This was observed only in ep0_rxstate() with g_ether loaded and the device connected to a MS Windows host PC. Anticipatively fixed ep0_txstate() as well.

The patch fixes this problem (and the related problem that installing altsetting 0 will fail if the device is suspended) by deferring the Set-Interface call until some later time when it is legal and can succeed.

We are not allowed to call drivers' probe routines during a system sleep transition between the "prepare" and "complete" callbacks, but that's exactly what we do when a driver doesn't have full suspend/resume support. Such drivers are unbound during the "suspend" call and reprobed during the "resume" call. The patch causes the reprobe step to be skipped if the "complete" callback hasn't been issued yet, i.e., if the interface's dev.power.status field is not equal to DPM_ON. Thus during the "resume" callback nothing bad will happen, and during the final "complete" callback the reprobing will occur as desired. This fixes the problem reported in Bugzilla #11263.

Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

Commit 3800345f723fd130d50434d4717b99d4a9f383c8 (pciehp: fix slot name) introduces the pciehp_slot_with_bus module parameter, which was intended to help work around broken firmware that assigns the same name to multiple slots. Commit 9e4f2e8d4ddb04ad16a3828cd9a369a5a5287009 (pciehp: add message about pciehp_slot_with_bus option) tells the user to use the above parameter in the event of a name collision. This approach is sub-optimal because it requires too much work from the user. Instead, let's rename the slot on behalf of the user. If firmware assigns the name N to multiple slots, then: The first registered slot is assigned N The second registered slot is assigned N-1 The third registered slot is assigned N-2 The Mth registered slot becomes N-M In the event we overflow the slot->name parameter, we report an error to the user. This is a temporary fix until the entire PCI core can be reworked such that individual drivers no longer have to manage their own slot names.

However, some hardresets can't wait for device readiness and skipping SRST can cause timeout or other failures during revalidation. Always perform follow-up SRST if hardreset returns -EAGAIN. This makes reset paths more predictable and thus less error-prone. While at it, move hardreset error checking such that it's done right after hardreset is finished. This simplifies followup SRST condition check a bit and makes the reset path easier to modify.

However, it turned out that the controller just didn't like issuing SRST after hardreset w/o clearing SError first. Interestingly, the SRST itself succeeds but the following commands fail. If SError is cleared between hardreset and SRST, which is the default behavior now, everything works fine and SIS controllers work with PMPs happily. Remove PMP blacklisting for SIS AHCIs.

Having been through the drivers I've added helpers for using_udma/using_mwdma dma_enabled so that people don't open code ranges that may change (eg if UDMA8 appears somewhere) Thanks to David for the initial bits [and added fix for pata_oldpiix from and signed-off-by Dave Mueller -jg] Signed-off-by: Alan Cox Signed-off-by: Jeff Garzik --- drivers/ata/libata-core.c | 4 ++-- drivers/ata/pata_acpi.c | 2 +- drivers/ata/pata_atiixp.c | 2 +- drivers/ata/pata_cs5530.c | 6 +++--- drivers/ata/pata_oldpiix.c | 2 +- drivers/ata/pata_sc1200.c | 6 +++--- 6 files changed, 11 insertions(+), 11 deletions(-) (limited to 'drivers') diff --git a/drivers/ata/libata-core.c b/drivers/ata/libata-core.c index 5f8f57a..79e3a8e 100644 --- a/drivers/ata/libata-core.c +++ b/drivers/ata/libata-core.c @@ -3288,7 +3288,7 @@ int ata_do_set_mode(struct ata_link *link, struct ata_device **r_failed_dev) dev->dma_mode = ata_xfer_mask2mode(dma_mask); found = 1; - if (dev->dma_mode != 0xff) + if (ata_dma_enabled(dev)) used_dma = 1; } if (!found) @@ -3313,7 +3313,7 @@ int ata_do_set_mode(struct ata_link *link, struct ata_device **r_failed_dev) /* step 3: set host DMA timings */ ata_link_for_each_dev(dev, link) { - if (!ata_dev_enabled(dev) || dev->dma_mode == 0xff) + if (!ata_dev_enabled(dev) || !ata_dma_enabled(dev)) continue; dev->xfer_mode = dev->dma_mode; diff --git a/drivers/ata/pata_acpi.c b/drivers/ata/pata_acpi.c index fbe6057..eb919c1 100644 --- a/drivers/ata/pata_acpi.c +++ b/drivers/ata/pata_acpi.c @@ -181,7 +181,7 @@ static unsigned int pacpi_qc_issue(struct ata_queued_cmd *qc) if (adev != acpi->last) { pacpi_set_piomode(ap, adev); - if (adev->dma_mode) + if (ata_dma_enabled(adev)) pacpi_set_dmamode(ap, adev); acpi->last = adev; } diff --git a/drivers/ata/pata_atiixp.c b/drivers/ata/pata_atiixp.c index d7de7ba..e8a0d99 100644 --- a/drivers/ata/pata_atiixp.c +++ b/drivers/ata/pata_atiixp.c @@ -183,7 +183,7 @@ static void atiixp_bmdma_start(struct ata_queued_cmd *qc) u16 tmp16; pci_read_config_word(pdev, ATIIXP_IDE_UDMA_CONTROL, &tmp16); - if (adev->dma_mode >= XFER_UDMA_0) + if (ata_using_udma(adev)) tmp16 |= (1 << dn); else tmp16 &= ~(1 << dn); diff --git a/drivers/ata/pata_cs5530.c b/drivers/ata/pata_cs5530.c index 744beeb..0c4b271 100644 --- a/drivers/ata/pata_cs5530.c +++ b/drivers/ata/pata_cs5530.c @@ -149,10 +149,10 @@ static unsigned int cs5530_qc_issue(struct ata_queued_cmd *qc) struct ata_device *prev = ap->private_data; /* See if the DMA settings could be wrong */ - if (adev->dma_mode != 0 && adev != prev && prev != NULL) { + if (ata_dma_enabled(adev) && adev != prev && prev != NULL) { /* Maybe, but do the channels match MWDMA/UDMA ? */ - if ((adev->dma_mode >= XFER_UDMA_0 && prev->dma_mode < XFER_UDMA_0) || - (adev->dma_mode < XFER_UDMA_0 && prev->dma_mode >= XFER_UDMA_0)) + if ((ata_using_udma(adev) && !ata_using_udma(prev)) || + (ata_using_udma(prev) && !ata_using_udma(adev))) /* Switch the mode bits */ cs5530_set_dmamode(ap, adev); } diff --git a/drivers/ata/pata_oldpiix.c b/drivers/ata/pata_oldpiix.c index e678af3..df64f24 100644 --- a/drivers/ata/pata_oldpiix.c +++ b/drivers/ata/pata_oldpiix.c @@ -198,7 +198,7 @@ static unsigned int oldpiix_qc_issue(struct ata_queued_cmd *qc) if (adev != ap->private_data) { oldpiix_set_piomode(ap, adev); - if (adev->dma_mode) + if (ata_dma_enabled(adev)) oldpiix_set_dmamode(ap, adev); } return ata_sff_qc_issue(qc); diff --git a/drivers/ata/pata_sc1200.c b/drivers/ata/pata_sc1200.c index cbab397..0278fd2 100644 --- a/drivers/ata/pata_sc1200.c +++ b/drivers/ata/pata_sc1200.c @@ -167,10 +167,10 @@ static unsigned int sc1200_qc_issue(struct ata_queued_cmd *qc) struct ata_device *prev = ap->private_data; /* See if the DMA settings could be wrong */ - if (adev->dma_mode != 0 && adev != prev && prev != NULL) { + if (ata_dma_enabled(adev) && adev != prev && prev != NULL) { /* Maybe, but do the channels match MWDMA/UDMA ? */ - if ((adev->dma_mode >= XFER_UDMA_0 && prev->dma_mode < XFER_UDMA_0) || - (adev->dma_mode < XFER_UDMA_0 && prev->dma_mode >= XFER_UDMA_0)) + if ((ata_using_udma(adev) && !ata_using_udma(prev)) || + (ata_using_udma(prev) && !ata_using_udma(adev))) /* Switch the mode bits */ sc1200_set_dmamode(ap, adev); } -- cgit v1.1 From 4ef281853474389fea952e9e59650e599ecf2d62 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Fri, 22 Aug 2008 02:33:23 -0400 Subject: [libata] pata_it821x: fix warning Reported by Andrew Morton: drivers/ata/pata_it821x.c: In function 'it821x_port_start': drivers/ata/pata_it821x.c:609: warning: 'mtype' may be used uninitialized in this function Pretty horrid fix, but so's a warning..

Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Sat, 23 Aug 2008 21:45:21 -0700 Subject: Fix oops in acer_wmi driver (acer_wmi_init) The acer_wmi driver does a DMI scan for quirks, and then sets flags into the "interface" datastructure for some cases. However, the quirks happen real early before "interface" is per se initialized from NULL. The patch below 1) adds a NULL pointer check and 2) (re)runs the quirks at the end, when "interface" has it's final value.

Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

This patch makes Linux PNPACPI ignore the bit. The ACPI spec contains examples of PCI Interrupt Link devices marked as ResourceProducers, but many BIOSes mark them as ResourceConsumers. I also checked with a Windows contact, who said: Windows uses only "resource consumer" when dealing with interrupts. There's no useful way of looking at a resource producer of interrupts. ... NT-based Windows largely infers the producer/consumer stuff from the device type and ignores the bits in the namespace. This was necessary because Windows 98 ignored them and early namespaces contained random junk. The reason I want to change this is because if PNPACPI devices exclude ResourceProducer IRQ resources, we can't write PNP drivers for those devices. For example, on machines such as the the HP rx7620, rx7640, rx8620, rx8640, and Superdome, HPET interrupts are ResourceProducers. The HPET driver currently has to use acpi_bus_register_driver() and do its own _CRS parsing, even though it requires absolutely no ACPI-specific functionality. It would be better if the HPET driver were a PNP driver and took advantage of the _CRS parsing built into PNPACPI. This producer/consumer check was originally added here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2b8de5f50e4a302b83ebcd5b0120621336d50bd6 to fix this bug: http://bugzilla.kernel.org/show_bug.cgi?id=6292 However, the bug was related only to memory and I/O port resources, where the distinction is sensible and important to Linux. Given that the distinction is muddled for IRQ resources, I think it was a mistake to add the check there.

Since we're returning a s64, instead of getting the same negative number we desire, we get a very large positive number. This handles the case where v < vb->num_pages and ensures we get a small, negative, s64 as the result. Rusty: please push this for 2.6.27-rc4.

It breaks scsi/sg.c, bsg, and the block layer SG_IO with SCSI character devices (such as st). We hit a kernel crash with them. The problem is that cmd_filter code accesses to gendisk (having struct blk_scsi_cmd_filter) via inode->i_bdev->bd_disk. It works for only SCSI block device files. With character device files, inode->i_bdev leads you to struct cdev. inode->i_bdev->bd_disk->blk_scsi_cmd_filter isn't safe. SCSI ULDs don't expose gendisk; they keep it private. bsg needs to be independent on any protocols. We shouldn't change ULDs to expose their gendisk. This patch moves struct blk_scsi_cmd_filter from gendisk to request_queue, a common object, which eveyone can access to. The user interface doesn't change; users can change the filters via /sys/block/. gendisk has a pointer to request_queue so the cmd_filter code accesses to struct blk_scsi_cmd_filter.

It shrinks the stack from 1152 bytes to 192 bytes (the first version, that only did the e1000_option part, got it down to 600 bytes). About half comes from not using multiple "e1000_option" structures, the other half comes from turning the "e1000_opt_list[]" arrays into "static const" instead, so that gcc doesn't copy them onto the stack.

When stopping an md array, or just switching to read-only, we currently call invalidate_partition while holding the mddev lock. The main reason for this is probably to ensure all dirty buffers are flushed (invalidate_partition calls fsync_bdev). However if any dirty buffers are found, it will almost certainly cause a deadlock as starting writeout will require an update to the superblock, and performing that updates requires taking the mddev lock - which is already held. This deadlock can be demonstrated by running "reboot -f -n" with a root filesystem on md/raid, and some dirty buffers in memory. All other calls to stop an array should already happen after a flush. The normal sequence is to stop using the array (e.g. umount) which will cause __blkdev_put to call sync_blockdev. Then open the array and issue the STOP_ARRAY ioctl while the buffers are all still clean. So this invalidate_partition is normally a no-op, except for one case where it will cause a deadlock. So remove it. This patch possibly addresses the regression recored in http://bugzilla.kernel.org/show_bug.cgi?id=11460 and http://bugzilla.kernel.org/show_bug.cgi?id=11452 though it isn't yet clear how it ever worked.

The rcu lock is only needed while walking the linked list as uninteresting devices (failed or spares) can be removed at any time. So only take the rcu lock while actually walking the linked list. Take a refcount on the rdev during the time when we drop the lock and do the memalloc to start IO. When we return to the locked code, all the interesting devices on the list will not have moved, so we can simply use list_for_each_continue_rcu to pick up where we left off.

For users of this version of this particular UART IP it is fatal. This patch stores the information about the bug in the bugs field of the port structure when the port is first started up so subsequent opens can check this bit even if the test for the bug fails. David Brownell: "My own exposure to this is that the UART on DaVinci hardware, which TI allegedly derived from its original 16550 logic, has periodically gone from working to unusable with the mainline 8250.c ... and back and forth a bunch. Currently it's "unusable", a regression from some previous versions. With this patch from Will, it's usable."

This bug has been around for a LONG time. The MM warning is from late 2005, but the driver merged a year later ... so I'm puzzled why nobody noticed this before now. The fix involves noting that this buffer shouldn't be DMA-coherent; it's just used for normal DMA writes. So replace it with standard kmalloc() buffering and DMA mapping calls. This is the quickie fix. A better one would not rely on allocating large bounce buffers. (Note that dma_alloc_coherent could have failed too, but that case was ignored... kmalloc is a bit more likely to fail though.)

I have just fixed it up so it applies without fuzz to upstream kernels. Original patch and description from Shyam kumar Iyer: The issue [ibft module not displaying targets with short names] is because of an offset calculatation error in the iscsi_ibft.c code. Due to this error directory structure for the target in /sys/firmware/ibft does not get created and so the initiator is unable to connect to the target. Note that this bug surfaced only with an name that had a short section at the end. eg: "iqn.1984-05.com.dell:dell". It did not surface when the iqn's had a longer section at the end. eg: "iqn.2001-04.com.example:storage.disk2.sys1.xyz" So, the eot_offset was calculated such that an extra 48 bytes i.e. the size of the ibft_header which has already been accounted was subtracted twice. This was not evident with longer iqn names because they would overshoot the total ibft length more than 48 bytes and thus would escape the bug.

There are still some systems where the ACPI event handling doesn't cooperate. (Possibly related to bugid 11312, reporting the spontaneous disabling of RTC events.) Bug 11411 reported that changes to work around some ACPI event issues broke wake-from-S5 handling, as used for DVR applications. (They like to power off, then wake later to record programs.)

GFP_DMA allows allocation only for memory under 16M which causes allocation problems suspend/resume flows. Using kmalloc is temporal solution and some consistent/coherent allocation schema will be more correct. Since iwlwifi hardware supports 64bit address this solution should work on x86 (32 and 64bit) for now. This patch fixes memory freeing problem in the previous patch.

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags, and sets this flag for the Philips SPC200NC cam (which has its sensor installed upside down). The same flag is also needed and added for the Philips SPC300NC. Together with a patch to libv4l which adds flipping the image in software this fixes the upside down display with the SPC200NC cam.

The proper behaviour is to keep all succeded devices registered; 4) both n_devs and minor were using 0 as permissions. Better to have them with 0444. With the current patch, if n_devs specify a very large value, it will register all possible devices. For example, on a machine without any other V4L drivers loaded, with this patch, we will have something like: vivi: V4L2 device registered as /dev/video0 vivi: V4L2 device registered as /dev/video1 vivi: V4L2 device registered as /dev/video2 ... vivi: V4L2 device registered as /dev/video31 video_register_device_index: get_index failed Video Technology Magazine Virtual Video Capture Board ver 0.5.0 successfully loaded. 5) The number of allocated devices on success is now kept at n_devs: $ cat /sys/module/vivi/parameters/n_devs 32 Thanks to Henne for pointing that there were some issues at vivi.

If accounting of a queue is in error, logic borrowed from ivtv will cause an oops when flushing the queues for a stream. This change greatly simplifies the queue flush logic, and sets the queue back to sane defaults on a flush.

Thus, instead of looking at the resource number to determine whether it was a bridge resource or a regular resource (they have different alignment rules), we should just ask the resource for its alignment directly. The reason this broke only cardbus resources was that for the other types of resources, the old way of deciding alignment actually still happened to work. But CardBus bridge resources had been changed by commit 934b7024f0ed29003c95cef447d92737ab86dc4f ("Fix cardbus resource allocation") to look more like regular resources than PCI bridge resources from an alignment handling standpoint.

Please apply to 2.6.27-rc and acpi git. A more complete solution for this laptop will be included in an upcoming patch, hopefully for 2.6.28.

When using the sonixb driver in a dark room and given that the autoexposure algorithm starts with a setting most suitable for daylight, the picture produced by the cam may actually be 100% black leading to a avg_lum value of 0, so an avg_lum value of 0 does not always signal an exposure settings change (which it normally does). This patch adds a check for the really black image case and stops dropping all frames as invalid in this case.

This results in less pointer hopping when many fingers are on the trackpad. In addition, a finger counting method based on pressure information from all fingers is introduced.

Without this patch only dte irqs are used which may lead to overruns and cases of missing stop and extra bytes being read on the i2c bus. Use of wait irqs forces the hardware to pause and wait until the cpu is ready. Polling is also reworked in this patch to fix ms delay issues. Verified with bus analyzer and tested on MigoR and AP325RXA boards.

On those chipsets, we need to read out the timer value at least three times to get a correct result, for every once in a while (i.e. within a 3 ns window every 69.8 ns) the read returns a bogus result. During normal operation we work around this issue, but during initialization reading a bogus value may lead to -EINVAL even though the hardware is usable.

Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

Previously, broken hardreset could go unnoticed as it wasn't used during probing but when something goes wrong or after hotplug the problem will surface and bite hard. OSDL bug 11195 reports that sata_nv generic flavor falls into this category. Hardreset itself succeeds but PHY stays offline after hardreset. I tried longer debounce timing but the result was the same. http://bugzilla.kernel.org/show_bug.cgi?id=11195 So, it seems we'll have to drop hardreset from the generic flavor.
