drm/vmwgfx: Return error code from vmw_execbuf_copy_fence_user

2019-02-15T07:10:12+00:00

commit 728354c005c36eaf44b6e5552372b67e60d17f56 upstream. The function was unconditionally returning 0, and a caller would have to rely on the returned fence pointer being NULL to detect errors. However, the function vmw_execbuf_copy_fence_user() would expect a non-zero error code in that case and would BUG otherwise. So make sure we return a proper non-zero error code if the fence pointer returned is NULL.

drm/vmwgfx: Fix setting of dma masks

2019-02-15T07:10:12+00:00

commit 4cbfa1e6c09e98450aab3240e5119b0ab2c9795b upstream. Previously we set only the dma mask and not the coherent mask. Fix that. Also, for clarity, make sure both are initially set to 64 bits.

drm/vmwgfx: Fix buffer object eviction

2018-09-20T06:05:14+00:00

Commit 19be55701071 ("drm/ttm: add operation ctx to ttm_bo_validate v2") introduced a regression where the vmwgfx driver refused to evict a buffer that was still busy instead of waiting for it to become idle. Fix this. Cc: Signed-off-by: Thomas Hellstrom Reviewed-by: Christian König

drm/vmwgfx: Don't impose STDU limits on framebuffer size

If framebuffers are larger, we create bounce surfaces that are within STDU limits. Signed-off-by: Deepak Rawat Reviewed-by: Thomas Hellstrom Signed-off-by: Thomas Hellstrom

drm/vmwgfx: limit mode size for all display unit to texture_max

For all display units, limit mode size exposed to texture_max_width/ height as this is the maximum framebuffer size that virtual device can create. Signed-off-by: Deepak Rawat Reviewed-by: Sinclair Yeh Reviewed-by: Thomas Hellstrom Signed-off-by: Thomas Hellstrom

drm/vmwgfx: limit screen size to stdu_max during check_modeset

2018-09-20T06:00:03+00:00

For STDU individual screen target size is limited by SVGA_REG_SCREENTARGET_MAX_WIDTH/HEIGHT registers so add that limit during atomic check_modeset. An additional limit is placed in the update_layout ioctl to avoid requesting layouts that current user-space typically can't support. Also modified the comments to reflect current limitation on topology. Signed-off-by: Deepak Rawat Reviewed-by: Sinclair Yeh Reviewed-by: Thomas Hellstrom Signed-off-by: Thomas Hellstrom

drm/vmwgfx: don't check for old_crtc_state enable status

2018-09-20T06:00:02+00:00

During atomic check to prepare the new topology no need to check if old_crtc_state was enabled or not. This will cause atomic_check to fail because due to connector routing a crtc can be in atomic_state even if there was no change to enable status. Detected this issue with igt run.

Pull IDA updates from Matthew Wilcox: "A better IDA API: id = ida_alloc(ida, GFP_xxx); ida_free(ida, id); rather than the cumbersome ida_simple_get(), ida_simple_remove(). The new IDA API is similar to ida_simple_get() but better named. The internal restructuring of the IDA code removes the bitmap preallocation nonsense.

Reorder allocation to avoid an awkward lock/unlock/lock sequence. Simpler code due to being able to use ida_alloc_max(), even if we can't eliminate the driver's spinlock. Signed-off-by: Matthew Wilcox Reviewed-by: Sinclair Yeh
