Pull VFIO update from Alex Williamson: "VFIO updates include safer default file flags for VFIO device fds, an external user interface exported to allow other modules to hold references to VFIO groups, a fix to test for extended config space on PCIe and PCI-x, and new hot reset interfaces for PCI devices which allows the user to do PCI bus/slot resets when all of the devices affected by the reset are owned by the user. For this last feature, the PCI bus reset interface, I depend on changes already merged from Bjorn's PCI pull request. I therefore merged my tree up to commit cb3e433, which I think was the correct action, but as Stephen Rothwell noted, I failed to provide a commit message indicating why the merge was required. Sorry for that.

2013-09-09drm/i915: fix wait_for_pending_flips vs gpu hang deadlockDaniel Vetter
My g33 here seems to be shockingly good at hitting them all. This time around kms_flip/flip-vs-panning-vs-hang blows up: intel_crtc_wait_for_pending_flips correctly checks for gpu hangs and if a gpu hang is pending aborts the wait for outstanding flips so that the setcrtc call will succeed and release the crtc mutex. And the gpu hang handler needs that lock in intel_display_handle_reset to be able to complete outstanding flips. The problem is that we can race in two ways: - Waiters on the dev_priv->pending_flip_queue aren't woken up after we've the reset as pending, but before we actually start the reset work. This means that the waiter doesn't notice the pending reset and hence will keep on hogging the locks. Like with dev->struct_mutex and the ring->irq_queue wait queues we there need to wake up everyone that potentially holds a lock which the reset handler needs. - intel_display_handle_reset was called _after_ we've already signalled the completion of the reset work. Which means a waiter could sneak in, grab the lock and never release it (since the pageflips won't ever get released). Similar to resetting the gem state all the reset work must complete before we update the reset counter. Contrary to the gem reset we don't need to have a second explicit wake up call since that will have happened already when completing the pageflips. We also don't have any issues that the completion happens while the reset state is still pending - wait_for_pending_flips is only there to ensure we display the right frame. After a gpu hang&reset events such guarantees are out the window anyway. This is in contrast to the gem code where too-early wake-up would result in unnecessary restarting of ioctls. Also, since we've gotten these various deadlocks and ordering constraints wrong so often throw copious amounts of comments at the code. This deadlock regression has been introduced in the commit which added the pageflip reset logic to the gpu hang work: commit 96a02917a0131e52efefde49c2784c0421d6c439 Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Mon Feb 18 19:08:49 2013 +0200 drm/i915: Finish page flips and update primary planes after a GPU reset v2: - Add comments to explain how the wake_up serves as memory barriers for the atomic_t reset counter. - Improve the comments a bit as suggested by Chris Wilson. - Extract the wake_up calls before/after the reset into a little i915_error_wake_up and unconditionally wake up the pending_flip_queue waiters, again as suggested by Chris Wilson. v3: Throw copious amounts of comments at i915_error_wake_up as suggested by Chris Wilson.

2013-09-07Input: evdev - add EVIOCREVOKE ioctlDavid Herrmann
If we have multiple sessions on a system, we normally don't want background sessions to read input events. Otherwise, it could capture passwords and more entered by the user on the foreground session. This is a real world problem as the recent XMir development showed: http://mjg59.dreamwidth.org/27327.html We currently rely on sessions to release input devices when being deactivated. This relies on trust across sessions. But that's not given on usual systems. We therefore need a way to control which processes have access to input devices. With VTs the kernel simply routed them through the active /dev/ttyX. This is not possible with evdev devices, though. Moreover, we want to avoid routing input-devices through some dispatcher-daemon in userspace (which would add some latency). This patch introduces EVIOCREVOKE. If called on an evdev fd, this revokes device-access irrecoverably for that *single* open-file. Hence, once you call EVIOCREVOKE on any dup()ed fd, all fds for that open-file will be rather useless now (but still valid compared to close()!). This allows us to pass fds directly to session-processes from a trusted source. The source keeps a dup()ed fd and revokes access once the session-process is no longer active. Compared to the EVIOCMUTE proposal, we can avoid the CAP_SYS_ADMIN restriction now as there is no way to revive the fd again. Hence, a user is free to call EVIOCREVOKE themself to kill the fd. Additionally, this ioctl allows multi-layer access-control (again compared to EVIOCMUTE which was limited to one layer via CAP_SYS_ADMIN). A middle layer can simply request a new open-file from the layer above and pass it to the layer below. Now each layer can call EVIOCREVOKE on the fds to revoke access for all layers below, at the expense of one fd per layer. There's already ongoing experimental user-space work which demonstrates how it can be used: http://lists.freedesktop.org/archives/systemd-devel/2013-August/012897.html Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

IACTH(Interrupt aggregation counter threshold) value is allowed up to 0x1F and current setting value is the maximum. This value is related with NUTRS(max:0x20) of HCI's capability. Considering HCI controller doesn't support the maximum, IACTH setting should be adjusted with possible value. For that, existing 'ufshcd_config_int_aggr' is split into two part [reset, configure].

2013-09-06drm/i915: Delay disabling of VGA memory until vgacon->fbcon handoff is doneVille Syrjälä
When transitioning away from vgacon the system tries to save the current contents of the VGA memory, so that it can be cleanly handed off to fbcon (or whatever comes afterwards). The recent change commit 81b5c7bc8de3e6f63419139c2fc91bf81dea8a7d Author: Alex Williamson <alex.williamson@redhat.com> Date: Wed Aug 28 09:39:08 2013 -0600 i915: Update VGA arbiter support for newer devices caused i915 to disable VGA memory decode for the IGD when i915 is initializing. Unfortunately that happens before the vgacon->fbcon handoff so vgacon_save_screen() will read out all ones from the VGA memory. After the handoff fbcon will inherit the bogus state from vgacon, and pre-fills the fb with matching contents. The end result is a white rectangle in the top left corner of the screen, the size of which matches the now inactive VGA console. To remedy the situation delay the disabling of VGA memory until the vgacon->fbcon handoff has happened. Also rename i915_enable_vga to i915_enable_vga_mem to make the relationship between these functions clearer.
