2013-06-13drm/gma500: Increase max resolution for mode settingPatrik Jakobsson1-2/+2
commit cbbd379aa43890f36da934f5af619d2fb8ec3d87 upstream. By having a higher max resolution we can now set up a virtual framebuffer that spans several monitors. 4096 should be ok since we're gen 3 or higher and should be enough for most dual head setups.

2013-06-13drm/i915: no lvds quirk for hp t5740Ben Mesman1-2/+2
commit 45a211d75137b1ac869a8a758a6667f15827a115 upstream. Last year, a patch was made for the "HP t5740e Thin Client" (see http://lists.freedesktop.org/archives/dri-devel/2012-May/023245.html). This device reports an lvds panel, but does not really have one. The predecessor of this device is the "hp t5740", which also does not have an lvds panel. This patch will add the same quirk for this device.

2013-06-13drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC.Egbert Eich1-1/+1
commit 53d3b4d7778daf15900867336c85d3f8dd70600c upstream. In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used for DDC. Thus the code will always have to rely on a LVDS panel mode supplied by VBT. In most cases this succeeds, so this didn't get detected for quite a while.

2013-06-13drm: fix a use-after-free when GPU acceleration disabledHuacai Chen1-1/+5
commit b7ea85a4fed37835eec78a7be3039c8dc22b8178 upstream. When GPU acceleration is disabled, drm_vblank_cleanup() will free the vblank-related data, such as vblank_refcount, vblank_inmodeset, etc. But we found that drm_vblank_post_modeset() may be called after the cleanup, which use vblank_refcount and vblank_inmodeset. And this will cause a kernel panic. Fix this by return immediately if dev->num_crtcs is zero. This is the same thing that drm_vblank_pre_modeset() does.

2013-06-13radeon: Fix system hang issue when using KMS with older cardsAdis Hamzić13-45/+78
commit e49f3959a96dc279860af7e86e6dbcfda50580a5 upstream. The current radeon driver initialization routines, when using KMS, are written so that the IRQ installation routine is called before initializing the WB buffer and the CP rings. With some ASICs, though, the IRQ routine tries to access the GFX_INDEX ring causing a call to RREG32 with the value of -1 in radeon_fence_read. This, in turn causes the system to completely hang with some cards, requiring a hard reset. A call stack that can cause such a hang looks like this (using rv515 ASIC for the example here): * rv515_init (rv515.c) * radeon_irq_kms_init (radeon_irq_kms.c) * drm_irq_install (drm_irq.c) * radeon_driver_irq_preinstall_kms (radeon_irq_kms.c) * rs600_irq_process (rs600.c) * radeon_fence_process - due to SW interrupt (radeon_fence.c) * radeon_fence_read (radeon_fence.c) * hang due to RREG32(-1) The patch moves the IRQ installation to the card startup routine, after the ring has been initialized, but before the IRQ has been set. This fixes the issue, but requires a check to see if the IRQ is already installed, as is the case in the system resume codepath. I have tested the patch on three machines using the rv515, the rv770 and the evergreen ASIC. They worked without issues. This seems to be a known issue and has been reported on several bug tracking sites by various distributions (see links below). Most of reports recommend booting the system with KMS disabled and then enabling KMS by reloading the radeon module. For some reason, this was indeed a usable workaround, however, UMS is now deprecated and disabled by default.

The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project...

2013-06-13xhci - correct comp_mode_recovery_timer on return from hibernateTony Camuso1-1/+11
commit 77df9e0b799b03e1d5d9c68062709af5f637e834 upstream. Commit 71c731a2 (usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware) was a workaround for systems using the SN65LVPE502CP, controller, but it introduced a bug in resume from hibernate. The fix created a timer, comp_mode_recovery_timer, which is deleted from a timer list when xhci_suspend() is called. However, the hibernate image, including the timer list containing the comp_mode_recovery_timer, had already been saved before the timer was deleted. Upon resume from hibernate, the list containing the comp_mode_recovery_timer is restored from the image saved to disk, and xhci_resume(), assuming that the timer had been deleted by xhci_suspend(), makes a call to compliance_mode_recoery_timer_init(), which creates a new instance of the comp_mode_recovery_timer and attempts to place it into the same list in which it is already active, thus corrupting the list during the list_add() call. At this point, a call trace is emitted indicating the list corruption. Soon afterward, the system locks up, the watchdog times out, and the ensuing NMI crashes the system. The problem did not occur when resuming from suspend. In suspend, the image in RAM remains exactly as it was when xhci_suspend() deleted the comp_mode_recovery_timer, so there is no problem when xhci_resume() creates a new instance of this timer and places it in the still empty list. This patch avoids the problem by deleting the timer in xhci_resume() when resuming from hibernate. Now xhci_resume() can safely make the call to create a new instance of this timer, whether returning from suspend or hibernate. Thanks to Alan Stern for his help with understanding the problem. [Sarah reworked this patch to cover the case where the xHCI restore register operation fails, and (temp & STS_SRE) is true (and we re-init the host, including re-init for the compliance mode), but hibernate is false. The original patch would have caused list corruption in this case.] This patch should be backported to kernels as old as 3.2, that contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" Signed-off-by: Tony Camuso <tcamuso@redhat.com> Tested-by: Tony Camuso <tcamuso@redhat.com> Acked-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit d3263bc29706e42f74d8800807c2dedf320d77f1 upstream. Work around an IOMMU hardware bug where clearing the EVT_INT or PPR_INT bit in the status register may race with the hardware trying to set it again. When not handled the bit might not be cleared and we lose all future event or ppr interrupts.

commit 925fe08bce38d1ff052fe2209b9e2b8d5fbb7f98 upstream. Current driver does not clear the IOMMU event log interrupt bit in the IOMMU status register after processing an interrupt. This causes the IOMMU hardware to generate event log interrupt only once. This has been observed in both IOMMU v1 and V2 hardware.

commit bee980d9e9642e96351fa3ca9077b853ecf62f57 upstream. This avoids any other hardirq handler seeing a very stale jiffies value immediately after wakeup from a long idle period. The one observable symptom of this was a USB keyboard, with software keyboard repeat, which would always repeat a key immediately that it was pressed. This is due to the key press waking the guest, the key handler immediately runs, sees an old jiffies value, and then that jiffies value significantly updated, before the key is unpressed.

2013-06-07USB: UHCI: fix for suspend of virtual HP controllerAlan Stern1-1/+2
commit 997ff893603c6455da4c5e26ba1d0f81adfecdfc upstream. HP's virtual UHCI host controller takes a long time to suspend (several hundred microseconds), even when no devices are attached. This provokes a warning message from uhci-hcd in the auto-stop case. To prevent this from happening, this patch adds a test to avoid performing an auto-stop when the wait_for_hp quirk flag is set. The controller will still suspend through the normal runtime PM mechanism. And since that pathway includes a 1-ms delay, the slowness of the virtual hardware won't matter.

2013-06-07USB: xHCI: override bogus bulk wMaxPacketSize valuesAlan Stern1-8/+9
commit e4f47e3675e6f1f40906b785b934ce963e9f2eb3 upstream. This patch shortens the logic in xhci_endpoint_init() by moving common calculations involving max_packet and max_burst outside the switch statement, rather than repeating the same code in multiple case-specific statements. It also replaces two usages of max_packet which were clearly intended to be max_burst all along. More importantly, it compensates for a common bug in high-speed bulk endpoint descriptors. In many devices there is a bulk endpoint having a wMaxPacketSize value smaller than 512, which is forbidden by the USB spec. Some xHCI controllers can't handle this and refuse to accept the endpoint. This patch changes the max_packet value to 512, which allows the controller to use the endpoint properly. In practice the bogus maxpacket size doesn't matter, because none of the transfers sent via these endpoints are longer than the maxpacket value anyway.

2013-06-07TTY: Fix tty miss restart after we turn off flow-controlWang YanQing1-0/+8
commit dab73b4eb9ef924a2b90dab84e539076d82b256f upstream. I meet emacs hang in start if I do the operation below: 1: echo 3 > /proc/sys/vm/drop_caches 2: emacs BigFile 3: Press CTRL-S follow 2 immediately Then emacs hang on, CTRL-Q can't resume, the terminal hang on, you can do nothing with this terminal except close it. The reason is before emacs takeover control the tty, we use CTRL-S to XOFF it. Then when emacs takeover the control, it may don't use the flow-control, so emacs hang. This patch fix it. This patch will fix a kind of strange tty relation hang problem, I believe I meet it with vim in ssh, and also see below bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=465823 Signed-off-by: Wang YanQing <udknight@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit 2a0ebf80aa95cc758d4725f74a7016e992606a39 upstream. The value of "offd" comes off the instance->rcv_buf[] and we used it as the offset into an array. The problem is that we check the upper bound but not for negative values. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
