drm/i915/bios: ignore HDMI on port A

2017-10-12T09:51:25+00:00

commit 2ba7d7e0437127314864238f8bfcb8369d81075c upstream.

The hardware state readout oopses after several warnings when trying to
use HDMI on port A, if such a combination is configured in VBT. Filter
the combo out already at the VBT parsing phase.

v2: also ignore DVI (Ville)

drm: mali-dp: Fix transposed horizontal/vertical flip

2017-10-08T08:26:07+00:00

[ Upstream commit 7916efe5b57505080b3cebf5bdb228b4eda008ea ]

The horizontal and vertical flip flags were the wrong way around,
causing reflect-x to result in reflect-y being applied and vice-versa.
Fix them.

drm: mali-dp: Fix destination size handling when rotating

2017-10-08T08:26:07+00:00

[ Upstream commit edabb3c4cd2d035bc93a3d67b25a304ea6217301 ]

The destination rectangle provided by userspace in the CRTC_X/Y/W/H
properties is already expressed as the dimensions after rotation.
This means we shouldn't swap the width and height ourselves when a
90/270 degree rotation is requested, so remove the code doing the swap.

drm/amdkfd: fix improper return value on error

2017-10-08T08:26:05+00:00

[ Upstream commit 8bf793883da213864efc50c274d2b38ec0ca58b2 ]

In function kfd_wait_on_events(), when the call to copy_from_user()
fails, the value of return variable ret is 0. 0 indicates success, which
is inconsistent with the execution status. This patch fixes the bug by
assigning "-EFAULT" to ret when copy_from_user() returns an unexpected
value.

drm/i915/psr: disable psr2 for resolution greater than 32X20

2017-10-08T08:26:05+00:00

PSR2 is restricted to work with panel resolutions upto 3200x2000,
move the check to intel_psr_match_conditions and fully block psr.

drm/i915: Fix the overlay frontbuffer tracking

2017-10-08T08:26:02+00:00

[ Upstream commit 58d09ebdb4edf5d3ab3a2aee851ab0168bc83ec6 ]

Do the overlay frontbuffer tracking properly so that it matches
the state of the overlay on/off/continue requests.

One slight problem is that intel_frontbuffer_flip_complete()
may get delayed by an arbitrarily liong time due to the fact that
the overlay code likes to bail out when a signal occurs. So the
flip may not get completed until the ioctl is restarted. But fixing
that would require bigger surgery, so I decided to ignore it for now.

etnaviv: fix gem object list corruption

commit 518417525f3652c12fb5fad6da4ade66c0072fa3 upstream.

All manipulations of the gem_object list need to be protected by
the list mutex, as GEM objects can be created and freed in parallel.
This fixes a kernel memory corruption.

drm/sun4i: Implement drm_driver lastclose to restore fbdev console

commit 2a596fc9d974bb040eda9ab70bf8756fcaaa6afe upstream.

The drm_driver lastclose callback is called when the last userspace
DRM client has closed. Call drm_fbdev_cma_restore_mode to restore
the fbdev console otherwise the fbdev console will stop working.

drm/bridge: adv7511: Switch to using drm_kms_helper_hotplug_event()

2017-09-09T15:39:42+00:00

commit 6d5104c5a6b56385426e15047050584794bb6254 upstream.

In chasing down a previous issue with EDID probing from calling
drm_helper_hpd_irq_event() from irq context, Laurent noticed
that the DRM documentation suggests that
drm_kms_helper_hotplug_event() should be used instead.

Thus this patch replaces drm_helper_hpd_irq_event() with
drm_kms_helper_hotplug_event(), which requires we update the
connector.status entry and only call _hotplug_event() when the
status changes.
