2017-08-29drm/syncobj: Add a reset ioctl (v3)Jason Ekstrand4-0/+44
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: Jason Ekstrand <jason@jlekstrand.net> Reviewed-by: Christian König <christian.koenig@amd.com> (v1) Signed-off-by: Dave Airlie <airlied@redhat.com>
2017-08-29drm/syncobj: Add a syncobj_array_find helperJason Ekstrand1-31/+58
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.

2017-08-29drm/syncobj: Allow wait for submit and signal behavior (v5)Jason Ekstrand2-45/+208
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: Jason Ekstrand <jason@jlekstrand.net> Cc: Dave Airlie <airlied@redhat.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Christian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2017-08-29drm/syncobj: Add a CREATE_SIGNALED flagJason Ekstrand2-3/+55
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.

2017-08-29drm/syncobj: Add a callback mechanism for replace_fence (v3)Jason Ekstrand2-2/+97
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: Jason Ekstrand <jason@jlekstrand.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
2017-08-29drm/syncobj: add sync obj wait interface. (v8)Dave Airlie4-0/+158
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: Dave Airlie <airlied@redhat.com> Reviewed-by: Jason Ekstrand <jason@jlekstrand.net> Acked-by: Christian König <christian.koenig@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2017-08-29drm/syncobj: Add a race-free drm_syncobj_fence_get helper (v2)Jason Ekstrand2-1/+13
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: Jason Ekstrand <jason@jlekstrand.net> Acked-by: Christian König <christian.koenig@amd.com> (v1) Signed-off-by: Dave Airlie <airlied@redhat.com>

2017-08-29drm: kirin: Add mode_valid logic to avoid mode clocks we can't generateJohn Stultz2-0/+81
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.

2017-08-23drm/omap: work-around for omap3 display enableTomi Valkeinen1-17/+30
Seems that on omap3 enabling a crtc without any planes causes a sync lost flood. This only happens on the first enable, and after that it works. This looks like an HW issue and it's unclear why this is happening or how to fix it. This started happening after 897145d0c7010b4e07fa9bc674b1dfb9a2c6fff9 ("drm/omapdrm: Move commit_modeset_enables() before commit_planes()") which, as a work-around, changed omapdrm first to do the modeset enable, and plane set only after that.

7d267f068a8b4944d52e8b0ae4c8fcc1c1c5c5ba ("drm/omap: work-around for errata i886") changed how the PLL dividers and multipliers are calculated. While the new way should work fine for all the PLLs, it breaks omap5 PLLs. The issues seen are rather odd: seemed that the output clock rate is half of what we asked. It is unclear what's causing there issues. As a work-around this patch adds a "errata_i886" flag, which is set only for DRA7's PLLs, and the PLL setup is done according to that flag.

2017-08-23drm/omap: fix analog tv-out modecheckTomi Valkeinen1-14/+51
omapdrm rejects all venc (analog tv-out) videomodes, due to somewhat strict checking of the values, making tv-out unusable. We only support two videomodes, one for PAL and one for NTSC, so instead of trying to check every field in the videomode struct, this patch makes the driver check only the pixel clock and the size of the display.
