2019-05-03drm/etnaviv: initialize idle mask before querying the HW dbLucas Stach1-4/+2
If there is a match in the HW DB, the function is left early, before inititalizing the idle mask. Fix this by doing the init earlier, as only old GPUs, not present in the HW DB need a different idle mask.

We now destroy finished jobs from the worker thread to make sure that we never destroy a job currently in timeout processing. By this we avoid holding lock around ring mirror list in drm_sched_stop which should solve a deadlock reported by a user. v2: Remove unused variable. v4: Move guilty job free into sched code. v5: Move sched->hw_rq_count to drm_sched_start to account for counter decrement in drm_sched_stop even when we don't call resubmit jobs if guily job did signal. v6: remove unused variable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=109692 Acked-by: Chunming Zhou <david1.zhou@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Andrey Grodzovsky <andrey.grodzovsky@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/1555599624-12285-3-git-send-email-andrey.grodzovsky@amd.com

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-1/+0
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2019-01-03Remove 'type' argument from access_ok() functionLinus Torvalds1-7/+1
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument of the user address range verification function since we got rid of the old racy i386-only code to walk page tables by hand. It existed because the original 80386 would not honor the write protect bit when in kernel mode, so you had to do COW by hand before doing any user access. But we haven't supported that in a long time, and these days the 'type' argument is a purely historical artifact. A discussion about extending 'user_access_begin()' to do the range checking resulted this patch, because there is no way we're going to move the old VERIFY_xyz interface to that model. And it's best done at the end of the merge window when I've done most of my merges, so let's just get this done once and for all. This patch was mostly done with a sed-script, with manual fix-ups for the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form. There were a couple of notable cases: - csky still had the old "verify_area()" name as an alias. - the iter_iov code had magical hardcoded knowledge of the actual values of VERIFY_{READ,WRITE} (not that they mattered, since nothing really used it) - microblaze used the type argument for a debug printout but other than those oddities this should be a total no-op patch. I tried to fix up all architectures, did fairly extensive grepping for access_ok() uses, and the changes are trivial, but I may have missed something. Any missed conversion should be trivially fixable, though. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2018-11-05drm/scheduler: Add drm_sched_job_cleanupSharat Masetty1-0/+3
This patch adds a new API to clean up the scheduler job resources. This is primarliy needed in cases the job was created but was not queued to the scheduler queue. Additionally with this change, the layer which creates the scheduler job also gets to free up the job's resources and this entails moving the dma_fence_put(finished_fence) to the drivers ops free handler routines.

2018-09-14drm/etnaviv: add DMA configuration for etnaviv platform deviceLucas Stach1-6/+21
The etnaviv device is a virtual device backing the DRM device, which may drive multiple hardware GPU core devices. As most of the dma-mapping handling is done through the virtual device, we need to make sure that a proper DMA setup is in place. The easiest way to get a reasonable configuration is to let the virtual device share the DMA configuration with one of the GPU devices, so call of_dma_configure() with the right parameters manually. This assumes that all etnaviv driven GPU devices in the system share the same DMA configuration. If we ever encounter a SoC where the GPUs are on busses with different offsets or behind different IOMMUs that will require much deeper changes to the driver, as we would need to implement etnaviv specific versions of most of the DRM helper functions. For now we should be fine with this solution. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Tested-by: Guido Günther <agx@sigxcpu.org> Tested-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com>

2018-08-06drm/etnaviv: fix crash in GPU suspend when init failed due to buffer placementLucas Stach1-0/+1
When the suballocator was unable to provide a suitable buffer for the MMUv1 linear window, we roll back the GPU initialization. As the GPU is runtime resumed at that point we need to clear the kernel cmdbuf suballoc entry to properly skip any attempt to manipulate the cmdbuf when the GPU gets shut down in the runtime suspend later on.

2018-08-06drm/etnaviv: change return type to vm_fault_tSouptick Joarder2-29/+11
Use new return type vm_fault_t for fault handler. For now, this is just documenting that the function returns a VM_FAULT value rather than an errno. Once all instances are converted, vm_fault_t will become a distinct type. Ref- commit 1c8f422059ae ("mm: change return type to vm_fault_t") Previously vm_insert_page() returns err which driver mapped into VM_FAULT_* type. The new function vmf_insert_page() will replace this inefficiency by returning VM_FAULT_* type. vmf_error() is the newly introduce inline function in 4.17-rc6.

The documentation of drm_sched_job_init and drm_sched_entity_push_job has been clarified. Both functions should be called under a shared lock, to avoid jobs getting pushed into the scheduler queue in a different order than their sched_fence seqnos, which will confuse checks that are looking at the seqnos to infer information about completion order.
