2022-10-27drm/i915/perf: Move gt-specific data from i915->perf to gt->perfUmesh Nerlige Ramappa
Make perf part of gt as the OAG buffer is specific to a gt. The refactor eventually simplifies programming the right OA buffer and the right HW registers when supporting multiple gts.

2022-10-20drm/i915/selftests: Stop using kthread_stop()Tvrtko Ursulin
Since a7c01fa93aeb ("signal: break out of wait loops on kthread_stop()") kthread_stop() started asserting a pending signal which wreaks havoc with a few of our selftests. Mainly because they are not fully expecting to handle signals, but also cutting the intended test runtimes short due signal_pending() now returning true (via __igt_timeout), which therefore breaks both the patterns of: kthread_run() ..sleep for igt_timeout_ms to allow test to exercise stuff.. kthread_stop() And check for errors recorded in the thread. And also: Main thread | Test thread ---------------+------------------------------ kthread_run() | kthread_stop() | do stuff until __igt_timeout | -- exits early due signal -- Where this kthread_stop() was assume would have a "join" semantics, which it would have had if not the new signal assertion issue. To recap, threads are now likely to catch a previously impossible ERESTARTSYS or EINTR, marking the test as failed, or have a pointlessly short run time. To work around this start using kthread_work(er) API which provides an explicit way of waiting for threads to exit. And for cases where parent controls the test duration we add explicit signaling which threads will now use instead of relying on kthread_should_stop().

2022-10-14drm/i915: enable PS64 support for DG2Matthew Auld
It turns out that on production DG2/ATS HW we should have support for PS64. This feature allows to provide a 64K TLB hint at the PTE level, which is a lot more flexible than the current method of enabling 64K GTT pages for the entire page-table, since that leads to all kinds of annoying restrictions, as documented in: commit caa574ffc4aaf4f29b890223878c63e2e7772f62 Author: Matthew Auld <matthew.auld@intel.com> Date: Sat Feb 19 00:17:49 2022 +0530 drm/i915/uapi: document behaviour for DG2 64K support On discrete platforms like DG2, we need to support a minimum page size of 64K when dealing with device local-memory. This is quite tricky for various reasons, so try to document the new implicit uapi for this. With PS64, we can now drop the 2M GTT alignment restriction, and instead only require 64K or larger when dealing with lmem. We still use the compact-pt layout when possible, but only when we are certain that this doesn't interfere with userspace. Note that this is a change in uAPI behaviour, but hopefully shouldn't be a concern (IGT is at least able to autodetect the alignment), since we are only making the GTT alignment constraint less restrictive. Based on a patch from CQ Tang. v2: update the comment wrt scratch page v3: (Nirmoy) - Fix the selftest to actually use the random size, plus some comment improvements, also drop the rem stuff.

The prandom_u32() function has been a deprecated inline wrapper around get_random_u32() for several releases now, and compiles down to the exact same code. Replace the deprecated wrapper with a direct call to the real function. The same also applies to get_random_int(), which is just a wrapper around get_random_u32(). This was done as a basic find and replace.

2022-09-19drm/i915/mtl: Add MTL forcewake supportMatt Roper
MTL has separate forcewake tables for the primary/render GT and the media GT; each GT's intel_uncore will use a separate forcewake table and should only initialize the domains that are relevant to that GT. The GT ack register also moves to a new location of (GSI base + 0xDFC) on this platform. Note that although our uncore handlers take care of transparently redirecting all register accesses in the media GT's GSI range to their new offset at 0x380000, the forcewake ranges listed in the table should use the final, post-translation offsets. NOTE: There are two ranges in the media IP that have multicast registers where the two register instances reside in different power wells (either VD0 or VD2). We don't have an easy way to deal with this today (and in fact we don't even access these register ranges in the driver today), so for now we just mark those ranges as FORCEWAKE_ALL which will cause all of the media power wells to be grabbed, ensuring proper operation. If we start reading/writing in those ranges in the future, we can re-visit whether it's worth adding extra steering complexity into our forcewake support.

2022-03-21drm/i915: Prepare for multiple GTsTvrtko Ursulin
On a multi-tile platform, each tile has its own registers + GGTT space, and BAR 0 is extended to cover all of them. Up to four GTs are supported in i915->gt[], with slot zero shadowing the existing i915->gt0 to enable source compatibility with legacy driver paths. A for_each_gt macro is added to iterate over the GTs and will be used by upcoming patches that convert various parts of the driver to be multi-gt aware. Only the primary/root tile is initialized for now; the other tiles will be detected and plugged in by future patches once the necessary infrastructure is in place to handle them.

2022-03-07drm/i915: Remove the vm open countThomas Hellström
vms are not getting properly closed. Rather than fixing that, Remove the vm open count and instead rely on the vm refcount. The vm open count existed solely to break the strong references the vmas had on the vms. Now instead make those references weak and ensure vmas are destroyed when the vm is destroyed. Unfortunately if the vm destructor and the object destructor both wants to destroy a vma, that may lead to a race in that the vm destructor just unbinds the vma and leaves the actual vma destruction to the object destructor. However in order for the object destructor to ensure the vma is unbound it needs to grab the vm mutex. In order to keep the vm mutex alive until the object destructor is done with it, somewhat hackishly grab a vm_resv refcount that is released late in the vma destruction process, when the vm mutex is no longer needed. v2: Address review-comments from Niranjana - Clarify that the struct i915_address_space::skip_pte_rewrite is a hack and should ideally be replaced in an upcoming patch. - Remove an unneeded continue in clear_vm_list and update comment. v3: - Documentation update - Commit message formatting Co-developed-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Signed-off-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Signed-off-by: Thomas Hellström <thomas.hellstrom@linux.intel.com> Reviewed-by: Niranjana Vishwanathapura <niranjana.vishwanathapura@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220304082641.308069-2-thomas.hellstrom@linux.intel.com

If we have to contend with non-mappable LMEM, then we need to ensure the object fits within the mappable portion, like in the selftests, where we later try to CPU access the pages. However if it can't then we need to gracefully handle this, without throwing an error. Also it looks like TTM will return -ENOMEM, in ttm_bo_mem_space() after exhausting all possible placements.

On i915_selftest@live@gt_timelines, we create many contexts in loop and create and submit request and then destoy contexts. Destroying the context needs to disable scheduling, wait for G2H, deregister context and wait for G2H to destroy each context. Idling of the gt has to wait for all this to complete which is taking ~3sec for this test. Hence we are increasing the igt_flush_test's timeout for gt idling to 3Sec.
