2017-03-30drm/nouveau: Don't register Thunderbolt eGPU with vga_switcherooLukas Wunner
An external Thunderbolt GPU can neither drive the laptop's panel nor be powered off by the platform, so there's no point in registering it with vga_switcheroo. In fact, when the external GPU is runtime suspended, vga_switcheroo will cut power to the internal discrete GPU, resulting in a lockup.

2017-03-27drm/atomic: Introduce drm_atomic_helper_shutdownDaniel Vetter
The trouble here is that it does multiple atomic commits under one drm_modeset_lock_all, which breaks the behind-the-scenes acquire context magic that function pulls off. It's much better to have one overall atomic commit. That we still have multiple atomic commits prevents us from adding some pretty useful debug checks to the atomic machinery. Hence it is really a bad idea to call the legacy drm_crtc_force_disable_all() function. There's 2 atomic drivers using this still, nouveau and tinydrm. To fix this, introduce a new drm_atomic_helper_shutdown() by extracting the code from i915. While at it improve kernel-doc and catch future offenders by sprinkling a WARN_ON into the legacy function. We should probably move those into the legacy modeset helpers, too ... v2: Make it compile on arm drivers too (Noralf). v3: Correct kerneldoc to point at _disable_all().

2017-03-22drm/dp: Split drm_dp_mst_allocate_vcpiPandiyan, Dhinakaran
drm_dp_mst_allocate_vcpi() apart from setting up the vcpi structure, also finds if there are enough slots available. This check is a duplicate of that implemented in drm_dp_mst_find_vcpi_slots(). Let's move this check out and reuse the existing drm_dp_mst_find_vcpi_slots() function to check if there are enough vcpi slots before allocating them. This brings the check to one place. Additionally drivers that will use MST state tracking for atomic modesets can use the atomic version of find_vcpi_slots() and reuse drm_dp_mst_allocate_vcpi() Signed-off-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1489648231-30700-4-git-send-email-dhinakaran.pandiyan@intel.com

2017-03-14drm: Remove drm_pending_event->pidDaniel Vetter
We might as well dump the drm_file pointer, that's about as useful a cookie as the pid. Noticed while typing docs for drm_file and friends. Since the only consumer of this is the tracepoints I think we can safely change this - those tracepoints should not be uapi relevant at all. It all goes back to commit b9c2c9ae882f058084e13e339925dbf8d2d20271 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Thu Jul 1 16:48:09 2010 -0700 drm: add per-event vblank event trace points which doesn't give a special justification for using pid over a pointer. Also note that the nouveau code setting it is entirely pointless: Since this isn't a vblank event, it will never hit the vblank tracepoints.

2017-03-07drm/nouveau/fb/gf100-: rework ram detectionBen Skeggs
This commit reworks the RAM detection algorithm, using RAM-per-LTC to determine whether a board has a mixed-memory configuration instead of using RAM-per-FBPA. I'm not certain the algorithm is perfect, but it should handle all currently known configurations in the very least. This should fix GTX 970 boards with 4GiB of RAM where the last 512MiB isn't fully accessible, as well as only detecting half the VRAM on GF108 boards. As a nice side-effect, GP10x memory detection now reuses the majority of the code from earlier chipsets. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2017-03-07drm/nouveau/secboot: let callers interpret return value of blobsAlexandre Courbot
Since the HS blobs are provided and signed by NVIDIA, we cannot expect always-consistent behavior. In this case, on GP10x the unload blob may return 0x1d even though things have run perfectly well. This behavior has been confirmed by NVIDIA. So let the callers of the run_blob() hook receive the blob return's value (a positive integer) and decide what it means.

2017-03-07drm/nouveau/secboot: support for different load and unload falconsAlexandre Courbot
On some secure boot instances (e.g. gp10x) the load and unload blobs do not run on the same falcon. Support this case by introducing a new member to the ACR structure and making related functions take the falcon to use as an argument instead of assuming the boot falcon is to be used. The rule is that the load blob can be run on either the SEC or PMU falcons, but the unload blob must be always run on PMU.

2017-03-07drm/nouveau/falcon: support for EMEMAlexandre Courbot
On SEC, DMEM is unaccessible by the CPU when the falcon is running in LS mode. This makes communication with the firmware using DMEM impossible. For this purpose, a new kind of memory (EMEM) has been added. It works similarly to DMEM, with the difference that its address space starts at 0x1000000. For this reason, it makes sense to treat it like a special case of DMEM. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
