As part of the sync framework destaging, the sync_file.h header was moved, but an entry was not added on Kbuild to install it. This patch resolves this omission so that "make headers_install" installs this header. Fixes: 460bfc41 ("dma-buf/sync_file: de-stage sync_file headers") Reported-by:

It's perfectly legal for the sink to support 12bpc only for some lower resolution modes, while the higher resolution modes can only be used with 8bpc. So let's take the sink's max TMDS clock into account before we go and decide that a particular mode can be used with 12bpc. Signed-off-by:

drm_edid_to_eld() is just mean to cook up the ELD for the audio driver, so having it parse non-audio related stuff seems just wrong, and potentially could lead to that information not being even filled out if the function doesn't even get called. Let's move that stuff to the place where we parse the color formats and whatnot from the CEA ext block. Signed-off-by:

It's not a good idea to leave stale cea_rev in the drm_display_info. The current EDID might not even have a CEA ext block in which case we'd end up leaving the stale value in place. Signed-off-by:

Currently we use a linear walk to lookup a handle and return a dma-buf, and vice versa. A long overdue TODO task is to convert that to a hashtable. Since the initial implementation of dma-buf/prime, we now have resizeable hashtables we can use (and now a future task is to RCU enable the lookup!). However, this patch opts to use an rbtree instead to provide O(lgN) lookups (and insertion, deletion). rbtrees were chosen over using the RCU backed resizable hashtable to firstly avoid the reallocations (rbtrees can be embedded entirely within the parent struct) and to favour simpler code with predictable worst case behaviour. In simple testing, the difference between using the constant lookup and insertion of the rhashtable and the rbtree was less than 10% of the wall time (igt/benchmarks/prime_lookup) - both are dramatic improvements over the existing linear lists. v2: Favour rbtree over rhashtable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=94631Signed-off-by:

Before commit a3257256 ("drm: Lobotomize set_busid nonsense for !pci drivers"), several DRM drivers for platform devices used to expose an explicit "drm_driver.set_busid" callback, invariably backed by drm_platform_set_busid(). Commit a3257256 removed drm_platform_set_busid(), along with the referring .set_busid field initializations. This was justified because interchangeable functionality had been implemented in drm_dev_alloc() / drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward. However, commit a3257256 also removed drm_virtio_set_busid(), for which the same consolidation was not appropriate: this .set_busid callback had been implemented with drm_pci_set_busid(), and not drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's "virtio-vga" card; the drmGetBusid() function from libdrm would no longer return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable platform ones like "virtio0".

The runqueue worker currently issues a get() when a new node is processed, and a put() once a node is completed. The corresponding suspend and resume calls currently only do clock gating, but with the upcoming introduction of IOMMU runpm also the corresponding IOMMU domain gets enabled (for get()) and disabled (for put()). This introduces performance regressions with we mitigate here. Switch PM runtime to autosuspend, such that clock gating and IOMMU control only happens when the engine is idle for a 'long' time.

While the engine works on a runqueue node it does memory access to the buffers associated with that node. Make sure that the engine is idle when g2d_close() and/or g2d_remove() are called, i.e. buffer associated with the process (for g2d_close()), or all buffers (for g2d_remove()) can be safely be unmapped. We have to take into account that the engine might be in an undefined state, i.e. it hangs and doesn't become idle. In this case, we issue a hardware reset to return the hardware and the driver context into a proper state. Signed-off-by:

The driver might be closed (and/or removed) while there are still nodes queued for processing. Make sure to remove these nodes, which means all of them in the case of g2d_remove() and only those belonging to the corresponding process in g2d_close(). Signed-off-by:

This reverts commit b05984e2. The change, i.e. merging the sleep and runpm operations, produces a deadlock situation: (1) exynos_g2d_exec_ioctl() prepares a runqueue node and calls g2d_exec_runqueue() (2) g2d_exec_runqueue() calls g2d_dma_start() which gets runtime PM sync (3) runtime PM core calls g2d_runtime_resume() (4) g2d_runtime_resume() calls g2d_exec_runqueue(), which loops back to (2) Due to mutexes that are in place, a deadlock situation is created.

In case of some platforms fimd clocks can be configured to very low values, as a result refresh rate can be very low and driver/drm-core will timeout waiting for vblanks, it will result in premature removal of framebuffers and will cause oopses. The patch adds atomic_check callback to fimd to prevent setting such modes. Reported-by:

Andrzej Hajda authored
Exynos DRM devices update their registers at vblank time. Exynos-DRM uses custom mechanism to wait for vblank. This mechanism is error prone - variables are not updated atomically. As a result in certain circumstances user space can try to free buffers which are still in use by hardware, in such cases IOMMU can throw OOPS. The patch instead of fixing the mechanism replaces it with drm core helper. Signed-off-by:

VIDI driver uses fake vblank handler to generate vblank events. It was implemented using worker which slept for vblank time, additionally it did not work if there were no page flips. The patch replaces it with timer, uses drm_crtc_vblank_(on|off) helpers to manage it and fixes behavior for non-page-flip cases. This change allows further improvements of vblank in exynos-drm framework. Signed-off-by:
