KIQ doesn't really use the GPU scheduler. The base drivers generally use the KIQ ring directly rather than submitting IBs. However, amdgpu_sched_hw_submission (which defaults to 2) limits the number of outstanding fences to 2. KFD uses the KIQ for TLB flushes and the 2 fence limit hurts performance when there are several KFD processes running. v2: move some expressions to one line change KIQ sched_hw_submission to at least 16 v3: bump to 256 Reviewed-by:Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by:

Set the shadow flag on the shadow and not the parent, always bind shadow BOs during allocation instead of manually, use the reservation_object wrappers to grab the lock. This fixes a couple of issues with binding the shadow BOs as well as correctly evicting them when memory becomes tight. Signed-off-by:

This IOCTL provides a mechanism for userspace to trigger a sync object directly. There are other ways that userspace can trigger a syncobj such as submitting a dummy batch somewhere or hanging on to a triggered sync_file and doing an import. This just provides an easy way to manually trigger the sync object without weird hacks. The motivation for this IOCTL is Vulkan fences. Vulkan lets you create a fence already in the signaled state so that you can wait on it immediatly without stalling. We could also handle this with a new create flag to ask the driver to create a syncobj that is already signaled but the IOCTL seemed a bit cleaner and more generic. v2: - Take an array of sync objects (Dave Airlie) v3: - Throw -EINVAL if pad != 0 Signed-off-by:

This just resets the dma_fence to NULL so it looks like it's never been signaled. This will be useful once we add the new wait API for allowing wait on "submit and signal" behavior. v2: - Take an array of sync objects (Dave Airlie) v3: - Throw -EINVAL if pad != 0 Signed-off-by:

The wait ioctl has a bunch of code to read an syncobj handle array from userspace and turn it into an array of syncobj pointers. We're about to add two new IOCTLs which will need to work with arrays of syncobj handles so let's make some helpers. Signed-off-by:

Vulkan VkFence semantics require that the application be able to perform a CPU wait on work which may not yet have been submitted. This is perfectly safe because the CPU wait has a timeout which will get triggered eventually if no work is ever submitted. This behavior is advantageous for multi-threaded workloads because, so long as all of the threads agree on what fences to use up-front, you don't have the extra cross-thread synchronization cost of thread A telling thread B that it has submitted its dependent work and thread B is now free to wait. Within a single process, this can be implemented in the userspace driver by doing exactly the same kind of tracking the app would have to do using posix condition variables or similar. However, in order for this to work cross-process (as is required by VK_KHR_external_fence), we need to handle this in the kernel. This commit adds a WAIT_FOR_SUBMIT flag to DRM_IOCTL_SYNCOBJ_WAIT which instructs the IOCTL to wait for the syncobj to have a non-null fence and then wait on the fence. Combined with DRM_IOCTL_SYNCOBJ_RESET, you can easily get the Vulkan behavior. v2: - Fix a bug in the invalid syncobj error path - Unify the wait-all and wait-any cases v3: - Unify the timeout == 0 case a bit with the timeout > 0 case - Use wait_event_interruptible_timeout v4: - Use proxy fence v5: - Revert to a combination of v2 and v3 - Don't use proxy fences - Don't use wait_event_interruptible_timeout because it just adds an extra layer of callbacks Signed-off-by:

This requests that the driver create the sync object such that it already has a signaled dma_fence attached. Because we don't need anything in particular (just something signaled), we use a dummy null fence. This is useful for Vulkan which has a similar flag that can be passed to vkCreateFence.

It is useful in certain circumstances to know when the fence is replaced in a syncobj. Specifically, it may be useful to know when the fence goes from NULL to something valid. This does make syncobj_replace_fence a little more expensive because it has to take a lock but, in the common case where there is no callback list, it spends a very short amount of time inside the lock. v2: - Don't lock in drm_syncobj_fence_get. We only really need to lock around fence_replace to make the callback work. v3: - Fix the cb_list comment to make kbuild happy Signed-off-by:

This interface will allow sync object to be used to back Vulkan fences. This API is pretty much the vulkan fence waiting API, and I've ported the code from amdgpu. v2: accept relative timeout, pass remaining time back to userspace. v3: return to absolute timeouts. v4: absolute zero = poll, rewrite any/all code to have same operation for arrays return -EINVAL for 0 fences. v4.1: fixup fences allocation check, use u64_to_user_ptr v5: move to sec/nsec, and use timespec64 for calcs. v6: use -ETIME and drop the out status flag. (-ETIME is suggested by ickle, I can feel a shed painting) v7: talked to Daniel/Arnd, use ktime and ns everywhere. v8: be more careful in the timeout calculations use uint32_t for counter variables so we don't overflow graciously handle -ENOINT being returned from dma_fence_wait_timeout Signed-off-by: -

The atomic exchange operation in drm_syncobj_replace_fence is sufficient for the case where it races with itself. However, if you have a race between a replace_fence and dma_fence_get(syncobj->fence), you may end up with the entire replace_fence happening between the point in time where the one thread gets the syncobj->fence pointer and when it calls dma_fence_get() on it. If this happens, then the reference may be dropped before we get a chance to get a new one. The new helper uses dma_fence_get_rcu_safe to get rid of the race. This is also needed because it allows us to do a bit more than just get a reference in drm_syncobj_fence_get should we wish to do so. v2: - RCU isn't that scary - Call rcu_read_lock/unlock - Don't rename fence to _fence - Make the helper static inline Signed-off-by:

Currently the hikey dsi logic cannot generate accurate byte clocks values for all pixel clock values. Thus if a mode clock is selected that cannot match the calculated byte clock, the device will boot with a blank screen. This patch uses the new mode_valid callback (many thanks to Jose Abreu for upstreaming it!) to ensure we don't select modes we cannot generate. Also, since the ade crtc code will adjust the mode in mode_set, this patch also adds a mode_fixup callback which we use to make sure we are validating the mode clock that will eventually be used.

Can be used by user-space applications to test and verify the kernel command buffer error recovery functionality. Malicious user-space apps could potentially use this command to slow down graphics processing somewhat, but they could also accomplish the same thing using a random malformed command so this should be considered safe. At least as safe as it gets. Signed-off-by:

Previously we skipped the command buffer and added an extra fence to avoid hangs due to skipped fence commands. Now we instead restart the command buffer after the failing command, if there are any commands left. In addition we print out some information about the failing command and its location in the command buffer. Testing Done: ran glxgears using mesa modified to send the NOP_ERROR command before each 10th clear and verified that we detected the device error properly and that there were no other device errors caused by incorrectly ordered command buffers. Also ran the piglit "quick" test suite which generates a couple of device errors and verified that they were handled as intended. Signed-off-by:

This gets rid of the irq bottom half tasklets and instead performs the work needed in process context. We also convert irq-disabling spinlocks to ordinary spinlocks. This should decrease system latency for other system components, like sound for example but has the potential to increase latency for processes that wait on the GPU. Signed-off-by:
