2015-12-08Back merge tag 'v4.4-rc4' into drm-nextDave Airlie1-1/+1
We've picked up a few conflicts and it would be nice to resolve them before we move onwards.
2015-12-01virtio-gpu: use no-merge for fill-modesMarc-André Lureau1-1/+1
Avoid the sticky preferred mode bit by using the no-merge version of the function (this allows gnome-shell to resize to lower resolutions than the default resolution) Signed-off-by: Marc-André Lureau <[email protected]> Cc: [email protected] Signed-off-by: Dave Airlie <[email protected]>
2015-11-24drm: Pass the user drm_mode_fb_cmd2 as const to .fb_create()Ville Syrjälä2-3/+3
Drivers shouldn't clobber the passed in addfb ioctl parameters. i915 was doing just that. To prevent it from happening again, pass the struct around as const, starting all the way from internal_framebuffer_create().

2015-11-24drm: Remove unused fbdev_list membersLukas Wunner1-1/+0
I noticed that intel_fbdev->our_mode is unused. Introduced by 79e539453b34 ("DRM: i915: add mode setting support"). Then I noticed that intel_fbdev->fbdev_list is unused as well. Introduced by 386516744ba4 ("drm/fb: fix fbdev object model + cleanup properly.") in i915, nouveau and radeon. Subsequently cargo culted to amdgpu, ast, cirrus, qxl, udl, virtio and mgag200. Already removed from the latter with cc59487a05b1 ("drm/mgag200: 'fbdev_list' in 'struct mga_fbdev' is not used"). Remove it from the others.

Pull drm updates from Dave Airlie: "I Was Almost Tempted To Capitalise Every Word, but then I decided I couldn't read it myself! I've also got one pull request for the sti driver outstanding. It relied on a commit in Greg's tree and I didn't find out in time, that commit is in your tree now so I might send that along once this is merged. I also had the accidental misfortune to have access to a Skylake on my desk for a few days, and I've had to encourage Intel to try harder, which seems to be happening now. Here is the main drm-next pull request for 4.4. Highlights: New driver: vc4 driver for the Rasberry Pi VPU. (From Eric Anholt at Broadcom.) Core: Atomic fbdev support Atomic helpers for runtime pm dp/aux i2c STATUS_UPDATE handling struct_mutex usage cleanups. Generic of probing support. Documentation: Kerneldoc for VGA switcheroo code. Rename to gpu instead of drm to reflect scope. i915: Skylake GuC firmware fixes HPD A support VBT backlight fallbacks Fastboot by default for some systems FBC work BXT/SKL workarounds Skylake deeper sleep state fixes amdgpu: Enable GPU scheduler by default New atombios opcodes GPUVM debugging options Stoney support.

2015-10-16virtio-gpu: add & use virtio_gpu_queue_fenced_ctrl_bufferGerd Hoffmann2-7/+35
Add helper function to handle the submission of fenced control requests. Make sure we initialize the fence while holding the virtqueue lock, so requests can't be reordered. Signed-off-by: Gerd Hoffmann <[email protected]>
2015-10-16virtio-gpu: add virtio_gpu_queue_ctrl_buffer_lockedGerd Hoffmann1-4/+13
Add virtio_gpu_queue_ctrl_buffer_locked function, which does the same as virtio_gpu_queue_ctrl_buffer but does not take the virtqueue lock. The caller must hold the lock instead. Signed-off-by: Gerd Hoffmann <[email protected]>
2015-10-16drm/virtio: use %llu format string form atomic64_tArnd Bergmann2-3/+3
The virtgpu driver prints the last_seq variable using the %ld or %lu format string, which does not work correctly on all architectures and causes this compiler warning on ARM: drivers/gpu/drm/virtio/virtgpu_fence.c: In function 'virtio_timeline_value_str': drivers/gpu/drm/virtio/virtgpu_fence.c:64:22: warning: format '%lu' expects argument of type 'long unsigned int', but argument 4 has type 'long long int' [-Wformat=] snprintf(str, size, "%lu", atomic64_read(&fence->drv->last_seq)); ^ drivers/gpu/drm/virtio/virtgpu_debugfs.c: In function 'virtio_gpu_debugfs_irq_info': drivers/gpu/drm/virtio/virtgpu_debugfs.c:37:16: warning: format '%ld' expects argument of type 'long int', but argument 3 has type 'long long int' [-Wformat=] seq_printf(m, "fence %ld %lld\n", ^ In order to avoid the warnings, this changes the format strings to %llu and adds a cast to u64, which makes it work the same way everywhere.

2015-06-03Add virtio gpu driver.Dave Airlie15-0/+3375
This patch adds a kms driver for the virtio gpu. The xorg modesetting driver can handle the device just fine, the framebuffer for fbcon is there too. Qemu patches for the host side are under review currently. The pci version of the device comes in two variants: with and without vga compatibility. The former has a extra memory bar for the vga framebuffer, the later is a pure virtio device. The only concern for this driver is that in the virtio-vga case we have to kick out the firmware framebuffer. Initial revision has only 2d support, 3d (virgl) support requires some more work on the qemu side and will be added later.
