Our sysfs "modes" entries were broken because our preffered mode never had its name set correctly. This resulted in the first entry simply being called "preferred" followed by a list of other resolutions. Lets fix it by actually setting the name of mode (which is its resolution). This allows one to quickly validate the modes set by the open-vm-tools. Signed-off-by:

The default list was old and in particular lacking all common 16:9 resolutions, as well as some newer 16:10 ones. This makes them selectable in resolution change lists, which can be quite useful (for instance in case auto-fit isn't enabled). Signed-off-by:

I got real badly confused when trying to review a fix from Ville for this. Let's try to document better what's required for this, and check the minimal settings at runtime - we can't check ofc that there's indeed no races in the driver callback. Also noticed that the drm_vblank_restore version is unused, so lets unexport that while at it. Reviewed-by:

There are minor differences in the values for the threshold value and the scan line size between families of ASPEED SoC. Additionally the SCU registers for the output control and scratch registers differ between families. This adds device tree matching to parameterise these values, allowing us to add support for the AST2400 now, and in the future the AST2600. Reviewed-by:

TTM implements a rather extensive accounting of allocated memory. There are two reasons for this: 1. It tries to block userspace allocating a huge number of very small BOs without accounting for the kmalloced memory. 2. Make sure we don't over allocate and run into an OOM situation during swapout while trying to handle the memory shortage. This is only partially a good idea. First of all it is perfectly valid for an application to use all of system memory, limiting it to 50% is not really acceptable. What we need to take care of is that the application is held accountable for the memory it allocated. This is what control mechanisms like memcg and the normal Linux page accounting already do. Making sure that we don't run into an OOM situation while trying to cope with a memory shortage is still a good idea, but this is also not very well implemented since it means another opportunity of recursion from the driver back into TTM. So start to rework all of this by implementing a shrinker callback which allows for TT object to be swapped out if necessary. v2: Switch from limit to shrinker callback. v3: fix gfp mask handling, use atomic for swapable_pages, add debugfs v4: drop the extra gfp_mask checks Signed-off-by:

Functions in the atomic commit tail are not allowed to acquire the dmabuf's reservation lock. So we cannot legally call the GEM object's vmap functionality in atomic_update. Instead use struct drm_shadow_plane_state and friends. It vmaps the framebuffer BOs in prepare_fb and vunmaps them in cleanup_fb. The cursor plane state stores the mapping's address. The pinning of the BO is implicitly done by vmap. As an extra benefit, there's no source of runtime errors left in atomic_update. v2: * rebase patch onto struct drm_shadow_plane_state Signed-off-by:

Several drivers use GEM buffer objects as shadow buffers for the actual framebuffer memory. Right now, drivers do these vmap operations in their commit tail, which is actually not allowed by the locking rules for the dma-buf reservation lock. The involved BO has to be vmapped in the plane's prepare_fb callback and vunmapped in cleanup_fb. This patch introduces atomic helpers for such shadow planes. Plane functions manage the plane state for shadow planes. The provided implementations for prepare_fb and cleanup_fb vmap and vunmap all BOs of struct drm_plane_state.fb. The mappings are afterwards available in the plane's commit-tail functions. For now, all rsp drivers use the simple KMS helpers, so we add the plane callbacks and wrappers for simple KMS. The internal plane functions can later be exported as needed. v3: * documentation fixes v2: * make duplicate_state interface compatible with struct drm_plane_funcs Signed-off-by:
