2021-01-18drm/vmwgfx: Always evict vram _before_ disabling itDaniel Vetter
Other way round is a bit inconsistent (but not buggy in any kind). This is prep work so that ttm_resource_manager_set_used can assert that the resource manager is empty.

2021-01-18drm/vmwgfx: Drop svga_lockDaniel Vetter
This isn't actually protecting anything becuase: - when running, ttm_resource_manager->use_type is protected through vmw_private->reservation_semaphore against concurrent execbuf or well anything else that might evict or reserve buffers - during suspend/resume there's nothing else running, hence vmw_pm_freeze and vmw_pm_restore do not need to take the same lock. - this also holds for the SVGA_REG_ENABLE register write Hence it is safe to just remove that spinlock.

2021-01-18drm: Set vm_ops to GEM object's values during mmapThomas Zimmermann
The GEM mmap code relies on the GEM object's mmap callback to set the VMA's vm_ops field. This is easily forgotten and already led to a memory leak in the CMA helpers. Instead set the vm_ops field in the DRM core code to the GEM object's value. Drivers with different needs can override this in their mmap callback. v2: * support (vm_ops == NULL) if mmap is given; required by VRAM helpers Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Fixes: f5ca8eb6f9bd ("drm/cma-helper: Implement mmap as GEM CMA object functions") Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reported-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Tested-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Eric Anholt <eric@anholt.net> Cc: dri-devel@lists.freedesktop.org Link: https://patchwork.freedesktop.org/patch/msgid/20210115093038.10345-1-tzimmermann@suse.de

2021-01-14drm/sun4i: tcon: fix inverted DCLK polarityGiulio Benetti
During commit 88bc4178568b ("drm: Use new DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags") DRM_BUS_FLAG_* macros have been changed to avoid ambiguity but just because of this ambiguity previous DRM_BUS_FLAG_PIXDATA_(POS/NEG)EDGE were used meaning _SAMPLE_ not _DRIVE_. This leads to DLCK inversion and need to fix but instead of swapping phase values, let's adopt an easier approach Maxime suggested: It turned out that bit 26 of SUN4I_TCON0_IO_POL_REG is dedicated to invert DCLK polarity and this makes things really easier than before. So let's handle DCLK polarity by adding SUN4I_TCON0_IO_POL_DCLK_DRIVE_NEGEDGE as bit 26 and activating according to bus_flags the same way it is done for all the other signals polarity.

Currently, data for the device instance is held by vkms_device. Add a separate type, vkms_config to contain configuration details for the device and various modes to be later used by configfs. This config data stays constant once the device is created. Accordingly, add vkms_create and vkms_destroy to initialize/destroy device through configfs. Currently, they are being called from vkms_init and vkms_exit, but will be evoked from configfs later on. When configfs is added, device configuration will be tracked by configfs and only vkms device lifetime will be handled by vkms_init and vkms_exit functions. Modify usage of enable_cursor feature to reflect the changes in relevant files.

2021-01-12drm: distinguish return value of drm_dp_check_and_send_link_addressXiaogang Chen
drm_dp_check_and_send_link_address discovers MST device topology. It can return both positive and negative values. When it returns positive values there is no error found. If it returns negative values there is error found, such as get NAK , timeout, etc. Following drm_kms_helper_hotplug_event should be called when drm_dp_check_and_send_link_address returns positive value.

For example, my RX 5600 XT, which advertises 256MB, 512MB and 1GB.
