In the end each mipmap level has the same width or height because of that 11 bit is ored to the scaled down lod with and thus blows up the size again to the full size or more due to the power of two rounding afterwards. The attached patch changes this order so that the texture sizes are computed correct. Also the on error the yet missing inputs to the size computation are printed which helped me to find out where it really breaks.

When we are evicting from VRAM->RAM we allocate the ttm object, but we don't set the caching policy on it before blitting into it. This means on AGP we end up blitting into cached pages, and the CPU later flushes out on top of them. This was mostly seen as font corruption. The other question is why we don't evict VRAM->GTT in a lot of cases, this would save us some cache transitions since a lot of objects that are evicted from VRAM will probably end up being pulled back in a few operations later, and evicting them to system memory involves 2 unnecessary cache transitions.

There are at least two forms of the failure, (1) BUG: Scheduling while atomic, and (2) a fatal kernel page fault. This problem is reported in Bugzilla #14539. This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2, thus it is technically a regression; however, bisection did not locate any faulty patch. The fix was found by comparing the faulty code in rtl8187 with p54usb. My interpretation is that the handling of work queues in mac80211 changed enough to the LEDs to be unregistered before tasks on the work queues are cancelled. Previously, these actions could be done in either order. (Herton Ronaldo Krzesinski reports that the code is the same in 2.6.31, so this may be a candidate for 2.6.31.x. -- JWL) Signed-off-by: Larry Finger Reported-by: Rick Farina Tested-by: Rick Farina Cc: stable@kernel.org Signed-off-by: John W.

If a 'sync_max' has been set (via sysfs), it is wrong to clear it until a resync (or reshape or recovery ...) actually reached that point. So if a resync is interrupted (e.g. by device failure), leave 'resync_max' unchanged. This is particularly important for 'reshape' operations that do not change the size of the array. For such operations mdadm needs to monitor the reshape taking rolling backups of the section being reshaped. If resync_max gets cleared, the reshape can get ahead of mdadm and then the backups that mdadm creates are useless. This is suitable for 2.6.31.y stable kernels.

Ok, we really do need to revert this, even with Bart's sis5513.c fix in there. The problem is that several driver's ->set_pio_mode() method depends upon the drive->media type being set properly. Most of them use this to enable prefetching, which can only be done for disk media. But the commit being reverted here calls ->set_pio_mode() before it's setup. Actually it considers everything disk because that is the default media type set by ide_port_init_devices_data(). The set of drivers that depend upon the media type in their ->set_pio_method() are: drivers/ide/alim15x3.c drivers/ide/it8172.c drivers/ide/it8213.c drivers/ide/pdc202xx_old.c drivers/ide/piix.c drivers/ide/qd65xx.c drivers/ide/sis5513.c drivers/ide/slc90e66.c And it is possible that we could fix this by guarding the prefetching and other media dependent setting changes with a test on IDE_PFLAG_PROBING in hwif->port_flags, that's simply too risky for 2.6.32-rcX and -stable.

This problem happened when removing PCIe root port using PCI logical hotplug operation. The immediate cause of this problem is that the pointer to invalid data structure is passed to pcie_update_aspm_capable() by pcie_aspm_exit_link_state(). When pcie_aspm_exit_link_state() received a pointer to root port link, it unconfigures the root port link and frees its data structure at first. At this point, there are not links to configure under the root port and the data structure for root port link is already freed. So pcie_aspm_exit_link_state() must not call pcie_update_aspm_capable() and pcie_config_aspm_path(). This patch fixes the problem by changing pcie_aspm_exit_link_state() not to call pcie_update_aspm_capable() and pcie_config_aspm_path() if the specified link is root port link. ------------[ cut here ]------------ kernel BUG at drivers/pci/pcie/aspm.c:606! invalid opcode: 0000 [#1] SMP DEBUG_PAGEALLOC last sysfs file: /sys/devices/pci0000:40/0000:40:13.0/remove CPU 1 Modules linked in: shpchp Pid: 9345, comm: sysfsd Not tainted 2.6.32-rc5 #98 ProLiant DL785 G6 RIP: 0010:[] [] pcie_update_aspm_capable+0x15/0xbe RSP: 0018:ffff88082a2f5ca0 EFLAGS: 00010202 RAX: 0000000000000e77 RBX: ffff88182cc3e000 RCX: ffff88082a33d006 RDX: 0000000000000001 RSI: ffffffff811dff4a RDI: ffff88182cc3e000 RBP: ffff88082a2f5cc0 R08: ffff88182cc3e000 R09: 0000000000000000 R10: ffff88182fc00180 R11: ffff88182fc00198 R12: ffff88182cc3e000 R13: 0000000000000000 R14: ffff88182cc3e000 R15: ffff88082a2f5e20 FS: 00007f259a64b6f0(0000) GS:ffff880864600000(0000) knlGS:0000000000000000 CS: 0010 DS: 0018 ES: 0018 CR0: 000000008005003b CR2: 00007feb53f73da0 CR3: 000000102cc94000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process sysfsd (pid: 9345, threadinfo ffff88082a2f4000, task ffff88082a33cf00) Stack: ffff88182cc3e000 ffff88182cc3e000 0000000000000000 ffff88082a33cf00 <0> ffff88082a2f5cf0 ffffffff811dff52 ffff88082a2f5cf0 ffff88082c525168 <0> ffff88402c9fd2f8 ffff88402c9fd2f8 ffff88082a2f5d20 ffffffff811d7db2 Call Trace: [] pcie_aspm_exit_link_state+0xf5/0x11e [] pci_stop_bus_device+0x76/0x7e [] pci_stop_bus_device+0x2b/0x7e [] pci_remove_bus_device+0x15/0xb9 [] remove_callback+0x29/0x3a [] sysfs_schedule_callback_work+0x15/0x6d [] worker_thread+0x19d/0x298 [] ? worker_thread+0x148/0x298 [] ? sysfs_schedule_callback_work+0x0/0x6d [] ? autoremove_wake_function+0x0/0x38 [] ? worker_thread+0x0/0x298 [] kthread+0x7d/0x85 [] child_rip+0xa/0x20 [] ? restore_args+0x0/0x30 [] ? kthread+0x0/0x85 [] ? child_rip+0x0/0x20 Code: 89 e5 8a 50 48 31 c0 c0 ea 03 83 e2 07 e8 b2 de fe ff c9 48 98 c3 55 48 89 e5 41 56 49 89 fe 41 55 41 54 53 48 83 7f 10 00 74 04 <0f> 0b eb fe 48 8b 05 da 7d 63 00 4c 8d 60 e8 4c 89 e1 eb 24 4c RIP [] pcie_update_aspm_capable+0x15/0xbe RSP ---[ end trace 6ae0f65bdeab8555 ]--- Reported-by: Alex Chiang Signed-off-by: Kenji Kaneshige Tested-by: Alex Chiang Signed-off-by: Jesse Barnes --- drivers/pci/pcie/aspm.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'drivers') diff --git a/drivers/pci/pcie/aspm.c b/drivers/pci/pcie/aspm.c index 745402e8e49..5b7056cec00 100644 --- a/drivers/pci/pcie/aspm.c +++ b/drivers/pci/pcie/aspm.c @@ -656,8 +656,10 @@ void pcie_aspm_exit_link_state(struct pci_dev *pdev) free_link_state(link); /* Recheck latencies and configure upstream links */ - pcie_update_aspm_capable(root); - pcie_config_aspm_path(parent_link); + if (parent_link) { + pcie_update_aspm_capable(root); + pcie_config_aspm_path(parent_link); + } out: mutex_unlock(&aspm_lock); up_read(&pci_bus_sem); -- cgit v1.2.3 From 9e90c961134929678022aee0c68b16c1ed520614 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Fri, 6 Nov 2009 02:06:59 +0000 Subject: be2net: fix to set proper flow control on resume If be2 goes into suspend after a user changes the flow control settings, we are not programming them back after resume.

It's a temporary workaround that fixes a regression (an OOPS condition) and the real fix should be in the code that manages the i2c master on the dib7000p. But this fix does address the immmediate regression and should be merged upstream until we do a cleaner fix.

I spent some time going over the code and the NXP's tda18271 spec (ver.4 of it i think) and adding a lot of debug prints and walking/stepping through the calibration process. I found that when the powerscan fails to find a frequency, the rf calibration is not run and the default value is supposed to be used in its place (pulled from the RF_CAL_map table) - but something was getting goofed up there. Now, my c coding skills are very rusty, but i think root of the problem is a signedness issue with the math operation for calculating the rf_a1 and rf_a2 values in tda18271_rf_tracking_filters_init func, which results in values like 20648 for rf_a1 (when it should probably have a value like 0, or so slightly negative that it should be zero - this bad value for rf_a1 would in turn makes the approx calc within tda18271c2_rf_tracking_filters_correction go out of whack). The simplest solution i found was to explicitly convert the signedness of the denominator to avoid the implicit conversion. The values placed into the u32 rf_freq array should never exceed about 900mhz, so i think the s32 max value shouldn't be an issue in this case. I've tested it out a little, and even when i get a bcal=0 with the modified code, the default calibration value gets used, rf_a1 is zero, and the tuner seems to lock on the stream and mythtv seems to play it fine.

This is a problem specifically when running in V4L2_FIELD_ALTERNATE mode (probably the most common case). 1. The determination of which fields are associated with which buffers happens in videobuf, before the bttv driver gets a chance to queue the corresponding DMA. Thus by the point when the DMA is queued for a given buffer, the algorithm has to do the queuing based on the buffer's already assigned field type - not based on which field is "next" in the video stream. 2. The driver normally tries to queue both the top and bottom fields at the same time (see bttv_irq_next_video()). It tries to sort out top vs bottom by looking at the field type for the next 2 available buffers and assigning them appropriately. 3. However the bttv driver *always* actually processes the top field first. There's even an interrupt set aside for specifically recognizing when the top field has been processed so that it can be marked done even while the bottom field is still being DMAed. Given all of the above, if one gets into a situation where bttv_irq_next_video() gets entered when the first available buffer has been pre-associated as a bottom field, then the function is going to process the buffers out of order. That first available buffer will be put into the bottom field slot and the buffer after that will be put into the top field slot. Problem is, since the top field is always processed first by the driver, then that second buffer (the one after the first available buffer) will be the first one to be finished. Because of the strict fifo handling of all video buffers, then that top field won't be seen by the app until after the bottom field is also processed. Worse still, the app will get back the chronologically later bottom field first, *before* the top field is received. The buffer's timestamps will even be backwards. While not fatal to most TV apps, this behavior can subtlely degrade userspace deinterlacing (probably will cause jitter). That's probably why it has gone unnoticed. But it will also cause serious problems if the app in question discards all but the latest received buffer (a latency minimizing tactic) - causing one field to only ever be displayed since the other is now always late. Unfortunately once you get into this state, you're stuck this way - because having consumed two buffers, now the next time around the "first" available buffer will again be a bottom field and the same thing happens. How can we get into this state? In a perfect world, where there's always a few free buffers queued to the driver, it should be impossible. However if something disrupts streaming, e.g. if the userspace app can't queue free buffers fast enough for a moment due perhaps to a CPU scheduling glitch, then the driver can get momentarily starved and some number of fields will be dropped. That's OK. But if an odd number of fields get dropped, then that "first" available buffer might be the bottom field and now we're stuck... This patch fixes that problem by deliberately only setting up a single field for one frame if we don't get a top field as the first available buffer. By purposely skipping the other field, then we only handle a single buffer thus bringing things back into proper sync (i.e. top field first) for the next frame. To do this we just drop the few lines in bttv_irq_next_video() that attempt to set up the second buffer when that second buffer isn't for the bottom field. This is definitely a problem in when in V4L2_FIELD_ALTERNATE mode. In the other modes this change either has no effect or doesn't harm things any further anyway.

It is "optional" based on a comparison of the cropcap parameters of the previous vs the newly requested video standard. The comparison is being done with a memcmp(), a function which only returns a true value if the comparison actually fails. This if-statement appears to have been written to assume wrong memcmp() semantics. That is, it was re-initializing the cropping configuration only if the new video standard did NOT have different cropcap values. That doesn't make any sense. One definitely should reset things if the cropcap parameters are different - if there's any comparison to made at all. The effect of this problem was that a transition from, say, PAL to NTSC would leave in place old cropping setup that made sense for the PAL geometry but not for NTSC. If the application doesn't care about cropping it also won't try to reset the cropping configuration, resulting in an improperly cropped video frame. In the case I was testing this actually caused black video frames to be displayed. Another interesting effect of this bug is that if one does something which does NOT change the video standard and this function is run, then the cropping setup gets reset anyway - again because of the backwards comparison. It turns out that just running anything which merely opens and closes the video device node (e.g. v4l-info) will cause this to happen. One can argue that simply opening the device node and not doing anything to it should not mess with any of its state - but because of this behavior, any TV app which does such things (e.g. xawtv) probably therefore doesn't see the problem. The solution is to fix the sense of the if-statement. It's easy to see how this mistake could have been made given how memcmp() works. The patch is therefore removal of a single "!" character from the if-statement in set_tvnorm in bttv-driver.c.

That simply doesn't work when the application is doing things in an asynchronous manner. If the application went to the trouble to queue the buffer in the first place, then the driver should always attempt to complete it - even if the application at that moment has its attention turned elsewhere. Applications which always blocked waiting for I/O on the capture device would not have been affected by this. Applications which *mostly* blocked waiting for I/O on the capture device probably only would have been somewhat affected (frame lossage, at a rate which goes up as the application blocks less). Applications which never blocked on the capture device (e.g. polling only) however would never have been able to receive any video frames, since in that case this "is anyone waiting on this?" check on the buffer never would have evalutated true. This patch just deletes that harmful check against the buffer's wait queue.

They are used only in two drivers: 1. savagefb - and cause bug #11248 2. uvesafb Usage of these operations is misunderstood in both drivers so kill these operations, fix the bug #11248 and avoid confusion in the future. Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release). This defeats the purpose of these operations.
