The fb handle code assumes it deals with GEM objects. Because vmwgfx buffer objects were not actually GEM objects we were not able to implement that interface. Now that vmwgfx supports GEM buffer objects we can trivially implement create_handle for buffer object backed framebuffers. Among others this gets IGT's kms_getfb test passing.

This is initial change adding support for DRIVER_GEM to vmwgfx. vmwgfx was written before GEM and has always used TTM. Over the years the TTM buffers started inherting from GEM objects but vmwgfx never implemented GEM making it quite awkward. We were directly setting variables in GEM objects to not make DRM crash. This change brings vmwgfx inline with other DRM drivers and allows us to use a lot of DRM helpers which have depended on drivers with GEM support. Due to historical reasons vmwgfx splits the idea of a buffer and surface which makes it a littly tricky since either one can be used in most of our ioctl's which take user space handles. For now our BO's are GEM objects and our surfaces are opaque objects which are backed by GEM objects. In the future I'd like to combine those into a single BO but we don't want to break any of our existing ioctl's so it will take time to do it in a non-destructive way.

Mob/GMR id resource manager was lacking the debug print callback which meant that during memory errors we weren't getting the details which are needed to fix those errors.

vmwgfx shared very elaborate memory accounting with ttm. It was moved from ttm to vmwgfx in change f07069da ("drm/ttm: move memory accounting into vmwgfx v4") but because of complexity it was hard to maintain. Some parts of the code weren't freeing memory correctly and some were missing accounting all together. While those would be fairly easy to fix the fundamental reason for memory accounting in the driver was the ability to invoke shrinker which is part of TTM code as well (with support for unified memory hopefully coming soon). That meant that vmwgfx had a lot of code that was either unused or duplicating code from TTM. Removing this code also prevents excessive calls to global swapout which were common during memory pressure because both vmwgfx and TTM would invoke the shrinker when memory usage reached half of RAM.

If the drm_plane has a source width that's greater than the max width supported by a single hw overlay, then we assign a 'r_overlay' to it in omap_plane_atomic_check(). Both overlays should have the capabilities required to handle the source framebuffer. The only parameters that vary between the left and right hwoverlays are the src_w, crtc_w, src_x and crtc_x as we just even chop the fb into left and right halves. We also take care of not creating odd width size when dealing with YUV formats. Since both halves need to be 'appear' side by side the zpos is recalculated when dealing with dual overlay cases so that the other planes zpos is consistent. Depending on user space usage it is possible that on occasion the number of requested planes exceeds the numbers of overlays required to display them. In that case a failure would be returned for the plane that cannot be handled at that time. It is up to user space to make sure the H/W resource are not over-subscribed.

(re)assign the hw overlays to planes based on required caps, and to handle situations where we could not modify an in-use plane. This means all planes advertise the superset of formats and properties. Userspace must (as always) use atomic TEST_ONLY step for atomic updates, as not all planes may be available for use on every frame. The mapping of hwoverlays to plane is stored in omap_global_state, so that state updates are atomically committed in the same way that plane/etc state updates are managed. This is needed because the omap_plane_state keeps a pointer to the hwoverlay, and we don't want global state to become out of sync with the plane state if an atomic update fails, we hit deadlock/ backoff scenario, etc. The use of global_state_lock keeps multiple parallel updates which both re-assign hwoverlays properly serialized.

Global shared resources (like hw overlays) for omapdrm are implemented as a part of atomic state using the drm_private_obj infrastructure available in the atomic core. omap_global_state is introduced as a drm atomic private object. The two funcs omap_get_global_state() and omap_get_existing_global_state() are the two variants that will be used to access omap_global_state. drm_mode_config_init() needs to be called earlier because it creates/initializes the private_obj link list maintained by the atomic framework. The private_obj link list has to exist prior to calling drm_atomic_private_obj_init(). Similarly the cleanup handler are reordered appropriately.

Split out the hardware overlay specifics from omap_plane. To start, the hw overlays are statically assigned to planes.

Memory of BOs backed by TILER is not contiguous, but omap_gem_map_dma_buf() exports it like it is. This leads to (possibly) invalid memory accesses if another device imports such a BO. Fix that by providing sg that correctly describes TILER memory layout. Align TILER allocations to page, so importer to be able to correctly set its MMU if have one. Set export size accounting for the alignment. Also, make sure to destroy sg on unpin, as it is no longer valid. Tested on Motorola Droid4 by using GPU (sgx540) to render.

When we added the support for the AUX channel in commit 13afcdd7 ("drm/bridge: parade-ps8640: Add support for AUX channel") we forgot to set "drm_dev" to avoid the warning splat at the beginning of drm_dp_aux_register(). Since everything was working I guess I never noticed the splat when testing against mainline. In any case, it's easy to fix.

TTM takes full control over TTM_PL_SYSTEM placed buffers. This makes driver internal usage of TTM_PL_SYSTEM prone to errors because it requires the drivers to manually handle all interactions between TTM which can swap out those buffers whenever it thinks it's the right thing to do and driver. CPU buffers which need to be fenced and shared with accelerators should be placed in driver specific placements that can explicitly handle CPU/accelerator buffer fencing. Currently, apart, from things silently failing nothing is enforcing that requirement which means that it's easy for drivers and new developers to get this wrong. To avoid the confusion we can document this requirement and clarify the solution. This came up during a discussion on dri-devel: https://lore.kernel.org/dri-devel/232f45e9-8748-1243-09bf-56763e6668b3@amd.comSigned-off-by: Zack Rusin <zackr@vmware.com> Cc: Christian König <christian.koenig@amd.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211110145034.487512-1-zackr@vmware.com

For larger (bigger than a page) and noncontiguous mobs we have to create page tables that allow the host to find the memory. Those page tables just used regular system memory. Unfortunately in TTM those BO's are not allowed to be busy thus can't be fenced and we have to fence those bo's because we don't want to destroy the page tables while the host is still executing the command buffers which might be accessing them. To solve it we introduce a new placement VMW_PL_SYSTEM which is very similar to TTM_PL_SYSTEM except that it allows fencing. This fixes kernel oops'es during unloading of the driver (and pci hot remove/add) which were caused by busy BO's in TTM_PL_SYSTEM being present in the delayed deletion list in TTM (TTM_PL_SYSTEM manager is destroyed before the delayed deletions are executed) Signed-off-by: Zack Rusin <zackr@vmware.com> Reviewed-by: Martin Krastev <krastevm@vmware.com> Cc: Christian König <christian.koenig@amd.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211105193845.258816-5-zackr@vmware.com

The signaled bit is already used for quick testing if a fence is signaled.

I'm not sure why it is useful to know the number of fences in the reservation object, but we try to avoid exposing the dma_resv_shared_list() function. So use the iterator instead. If more information is desired we could use dma_resv_describe() as well.

It has been observed that with certain monitors such as the HP Z27n, the register 0x825e reads a value of 0x79 when the HDMI cable is connected and 0x78 when it is disconnected, i.e. bit 0 appears to correspond to the HDMI connection status and bit 2 is never set. Therefore, change the driver to check bit 0 instead of bit 2.

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting KMS helpers and CMA will now automatically enable CMA KMS helpers. Some drivers' Kconfig files did not correctly select KMS or CMA helpers. Fix this as part of the change.
