2021-08-10drm/vmwgfx: fix potential UAF in vmwgfx_surface.cDesmond Cheong Zhi Xi1-2/+2
drm_file.master should be protected by either drm_device.master_mutex or drm_file.master_lookup_lock when being dereferenced. However, drm_master_get is called on unprotected file_priv->master pointers in vmw_surface_define_ioctl and vmw_gb_surface_define_internal. This is fixed by replacing drm_master_get with drm_file_get_master.

2021-08-08drm/mgag200: Store values (not bits) in struct mgag200_pll_valuesThomas Zimmermann1-62/+91
The fields in struct mgag200_pll_values currently hold the bits of each register. Store the PLL values instead and let the PLL-update code figure out the bits for each register. Until now, the compute function either stored plain values or register bits in struct mgag200_pll_values. The rsp update function used the values as-is. This made it very hard to correctly interpret the stored values (e.g., for logging or debugging). With the cleanup, the stored values now have a clear meaning. v2: * add a bit more context in the commit message (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210714142240.21979-7-tzimmermann@suse.de

2021-08-08drm/mgag200: Split PLL setup into compute and update functionsThomas Zimmermann2-52/+198
The _set_plls() functions compute a pixel clock's PLL values and program the hardware accordingly. This happens during atomic commits. For atomic modesetting, it's better to separate computation and programming from each other. This will allow to compute the PLL value during atomic checks and catch unsupported modes early. Split the PLL setup into a compute and an update functions, and call them one after the other. Computed PLL values are store in struct mgag200_pll_values. There are four parameters for the PLL, m, n, p and s. Every compute function stores a value for each of these parameters, and the rsp update function makes the register bits from them. The values stored by the compute function are either plain values or register bits. An additional change is required to always store plain values. No functional changes.

2021-08-02drm/vkms: Map output framebuffer BOs with drm_gem_fb_vmap()Thomas Zimmermann3-14/+22
Abstract the framebuffer details by mappings its BOs with a call to drm_gem_fb_vmap(). Unmap with drm_gem_fb_vunamp(). Before, the output address with stored as raw pointer in the priv field of struct drm_writeback_job. Introduce the new type struct vkms_writeback_job, which holds the output mappings addresses while the writeback job is active. The patchset also cleans up some internal casting an setup of the output addresses.

2021-08-02drm/gem: Clear mapping addresses for unused framebuffer planesThomas Zimmermann1-1/+5
Set the returned mapping address to NULL if a framebuffer plane does not have a BO associated with it. Likewise, ignore mappings of NULL during framebuffer unmap operations. Allows users of the functions to perform unmap operations of certain BOs by themselfes.

2021-08-02drm: Define DRM_FORMAT_MAX_PLANESThomas Zimmermann4-17/+26
DRM uses a magic number of 4 for the maximum number of planes per color format. Declare this constant via DRM_FORMAT_MAX_PLANES and update the related code. Some code depends on the length of arrays that are now declared with DRM_FORMAT_MAX_PLANES. Convert it from '4' to ARRAY_SIZE. v2: * mention usage of ARRAY_SIZE() in the commit message (Maxime) * also fix error handling in drm_gem_fb_init_with_funcs() (kernel test robot) * include <drm/drm_fourcc.h> for DRM_FORMAT_MAX_PLANES Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210730183511.20080-2-tzimmermann@suse.de

2021-08-02drm: Fix oops in damage self-tests by mocking damage propertyDaniel Vetter1-216/+71
I've added a new check to make sure that drivers which insepct the damage property have it set up correctly, but somehow missed that this borke the damage selftest in the CI result noise. Fix it up by mocking enough of drm_device and drm_plane so we can call drm_plane_enable_fb_damage_clips() to make the new check happy. Since there's a lot of duplicated mock code already copy-pasted into each test I've also refactored this a bit to trim it down. v2: Squash in fixup from 0day for drivers/gpu/drm/selftests/test-drm_damage_helper.c:15:19: warning: symbol 'mock_device' was not declared.
