2019-04-08 | drm/i915/selftests: Mark live_forcewake_ops as unreliable | Chris Wilson | 1 | -0/+11 | |
A couple of machines in the farm show quite frequent errors in the powerwells not being released. Either there is an external agent interferring with the powerwells, or the powerwell doesn't quite behave as we anticipate -- either way, the test is not reliable enough to be enabled by default in CI. It has served its immediate purpose in providing coverage as we made tweaks to forcewake, so keep it available for future testing.

2019-03-20 | drm/i915/selftests: add test to verify get/put fw domains | Daniele Ceraolo Spurio | 1 | -6/+128 | |
Exercise acquiring and releasing forcewake around register reads. In order to read a register behind a GT powerwell, we need to instruct that powerwell to wake up using a forcewake. When we no longer require the GT powerwell, we tell the GT to release our forcewake. Inside the forcewake, the register read should work but outside it should just return garbage, 0 being the most common garbage. Thus we can detect when we are inside and outside of the forcewake with just a simple register read, and so can verify that the GT powerwell is released when we say so. v2: Picking the right forcewaked register to return 0 outside of forcewake is an art.

However, we expose the forcewake to userspace (only via debugfs, but nevertheless we do) and want to restore that upon resume or else our accounting will be off and we may not acquire the forcewake before we use it.

2018-06-12 | treewide: kzalloc() -> kcalloc() | Kees Cook | 1 | -1/+1 | |
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2017-11-10 | drm/i915: Acquire PUNIT->PMIC bus for intel_uncore_forcewake_reset() | Hans de Goede | 1 | -0/+3 | |
intel_uncore_forcewake_reset() does forcewake puts and gets as such we need to make sure that no-one tries to access the PUNIT->PMIC bus (on systems where this bus is shared) while it runs, otherwise bad things happen. Normally this is taken care of by the i915_pmic_bus_access_notifier() which does an intel_uncore_forcewake_get(FORCEWAKE_ALL) when some other driver tries to access the PMIC bus, so that later forcewake gets are no-ops (for the duration of the bus access). But intel_uncore_forcewake_reset gets called in 3 cases: 1) Before registering the pmic_bus_access_notifier 2) After unregistering the pmic_bus_access_notifier 3) To reset forcewake state on a GPU reset In all 3 cases the i915_pmic_bus_access_notifier() protection is insufficient. This commit fixes this race by calling iosf_mbi_punit_acquire() before calling intel_uncore_forcewake_reset(). In the case where it is called directly after unregistering the pmic_bus_access_notifier, we need to hold the punit-lock over both calls to avoid a race where intel_uncore_fw_release_timer() may execute between the 2 calls.

2017-09-13 | mm: treewide: remove GFP_TEMPORARY allocation flag | Michal Hocko | 1 | -1/+1 | |
GFP_TEMPORARY was introduced by commit e12ba74d8ff3 ("Group short-lived and reclaimable kernel allocations") along with __GFP_RECLAIMABLE. It's primary motivation was to allow users to tell that an allocation is short lived and so the allocator can try to place such allocations close together and prevent long term fragmentation. As much as this sounds like a reasonable semantic it becomes much less clear when to use the highlevel GFP_TEMPORARY allocation flag. How long is temporary? Can the context holding that memory sleep? Can it take locks? It seems there is no good answer for those questions. The current implementation of GFP_TEMPORARY is basically GFP_KERNEL | __GFP_RECLAIMABLE which in itself is tricky because basically none of the existing caller provide a way to reclaim the allocated memory. So this is rather misleading and hard to evaluate for any benefits. I have checked some random users and none of them has added the flag with a specific justification. I suspect most of them just copied from other existing users and others just thought it might be a good idea to use without any measuring. This suggests that GFP_TEMPORARY just motivates for cargo cult usage without any reasoning. I believe that our gfp flags are quite complex already and especially those with highlevel semantic should be clearly defined to prevent from confusion and abuse. Therefore I propose dropping GFP_TEMPORARY and replace all existing users to simply use GFP_KERNEL. Please note that SLAB users with shrinkers will still get __GFP_RECLAIMABLE heuristic and so they will be placed properly for memory fragmentation prevention. I can see reasons we might want some gfp flag to reflect shorterm allocations but I propose starting from a clear semantic definition and only then add users with proper justification. This was been brought up before LSF this year by Matthew [1] and it turned out that GFP_TEMPORARY really doesn't have a clear semantic. It seems to be a heuristic without any measured advantage for most (if not all) its current users. The follow up discussion has revealed that opinions on what might be temporary allocation differ a lot between developers. So rather than trying to tweak existing users into a semantic which they haven't expected I propose to simply remove the flag and start from scratch if we really need a semantic for short term allocations.
