drm/vkms: Hold gem object while still in-use

2020-05-07T01:51:46+00:00

We need to keep the reference to the drm_gem_object until the last access by vkms_dumb_create. Therefore, the put the object after it is used. This fixes a use-after-free issue reported by syzbot. While here, change vkms_gem_create() symbol to static.

drm/vkms: enable cursor by default

2020-05-07T01:51:01+00:00

This patch proposes a change in the behavior of the cursor to enable it as soon as the vkms module is added. Enabling the cursor by default appears to be an expected and more friendly behavior, especially when running IGT tests.

drm/vkms: Use simple encoder

The vkms driver uses an empty implementation for its encoder. Replace the code with the generic simple encoder. Signed-off-by: Thomas Zimmermann Reviewed-by: Laurent Pinchart Acked-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20200305155950.2705-21-tzimmermann@suse.de

drm: Garbage collect drm_dev_fini

It has become empty. Given the few users I figured not much point splitting this up. v2: Rebase over i915 changes. v3: Rebase over patch split fix.

drm/vkms: Use drmm_add_final_kfree

2020-03-26T14:26:51+00:00

With this we can drop the final kfree from the release function. v2: After drm_dev_init/drmm_add_final_kfree we need to clean up everything through a drm_dev_put. Rework the unwind code to match that.

VBLANK callbacks in struct drm_driver are deprecated in favor of their equivalents in struct drm_crtc_funcs. Convert vkms over.

drm/vkms: Fix typo and preposion in function documentation

2019-12-05T23:55:55+00:00

Fix typo in word 'blend' and in the word 'destination' and change preposition 'at' to 'of' in function 'blend' documentation. And change the task introduction word 'Todo' for the word all in uppercase - 'TODO'. With the TODO word all in uppercase (as it's the standard) it's easier to find the tasks that have to be done throughout the code. Changes since V3: Rodrigo: - Merge the patch series into a single patch since it contains one single logical change Changes since V2: - Add fix typo in word 'destination' - Add change of the preposition - Fix the name of the function in log message - Add the change in word 'Todo' Reviewed-by: Rodrigo Siqueira Signed-off-by: Gabriela Bittencourt Signed-off-by: Rodrigo Siqueira Link: https://patchwork.freedesktop.org/patch/msgid/20191104161424.18105-1-gabrielabittencourt00@gmail.com
