2016-10-04drm: virtio: reinstate drm_virtio_set_busid()Laszlo Ersek3-0/+12
Before commit a325725633c2 ("drm: Lobotomize set_busid nonsense for !pci drivers"), several DRM drivers for platform devices used to expose an explicit "drm_driver.set_busid" callback, invariably backed by drm_platform_set_busid(). Commit a325725633c2 removed drm_platform_set_busid(), along with the referring .set_busid field initializations. This was justified because interchangeable functionality had been implemented in drm_dev_alloc() / drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward. However, commit a325725633c2 also removed drm_virtio_set_busid(), for which the same consolidation was not appropriate: this .set_busid callback had been implemented with drm_pci_set_busid(), and not drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's "virtio-vga" card; the drmGetBusid() function from libdrm would no longer return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable platform ones like "virtio0".

2016-08-29drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying1-1/+2
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-08-12drm/fb-helper: Add a dummy remove_conflicting_framebuffersDaniel Vetter1-1/+2
Lots of drivers don't properly compile without this when CONFIG_FB=n. It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when it's disabled I think it makes sense to add it to drm_fb_helper.h. Long term we probably need to rethink all the logic to unload firmware framebuffer drivers, at least if we want to be able to move away from CONFIG_FB and fbcon. v2: Unfortunately just stubbing out remove_conflicting_framebuffers in drm_fb_helper.h upset gcc about static vs. non-static declarations, so a new wrapper it needs to be.

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter3-12/+0
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

2016-01-12virtio: make find_vqs() checkpatch.pl-friendlyStefan Hajnoczi1-1/+1
checkpatch.pl wants arrays of strings declared as follows: static const char * const names[] = { "vq-1", "vq-2", "vq-3" }; Currently the find_vqs() function takes a const char *names[] argument so passing checkpatch.pl's const char * const names[] results in a compiler error due to losing the second const. This patch adjusts the find_vqs() prototype and updates all virtio transports. This makes it possible for virtio_balloon.c, virtio_input.c, virtgpu_kms.c, and virtio_rpmsg_bus.c to use the checkpatch.pl-friendly type.

2015-12-11drm: Drop drm_helper_probe_single_connector_modes_nomerge()Ville Syrjälä1-1/+1
Now that the mode type bit merge logic is fixed to only merge between new probed modes, hopefully we can eliminat the special case for qxl and virtio. That is make the merge the mode type bits from all matching new probed modes, just like every other driver. qxl and virtio got excluded from the merging in commit 3fbd6439e463 ("drm: copy mode type in drm_mode_connector_list_update()") commit abce1ec9b08a ("Revert "drm: copy mode type in drm_mode_connector_list_update()"") commit b87577b7c768 ("drm: try harder to avoid regression when merging mode bits") Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Adam Jackson <ajax@redhat.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> [danvet: Resolve conflicts with doc updates.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
