2021-03-24drm/i915: cleanup the region class/instance encodingMatthew Auld
Get rid of the strange REGION_MAP encoding stuff and just use an explicit class/instance pair for each region. This better matches our future uAPI where all queryable regions are identified with a u16 class and u16 instance. v2: fix whitespace Signed-off-by: Matthew Auld <matthew.auld@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20210205102026.806699-1-matthew.auld@intel.com Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2021-03-24drm/i915/gt: Move the defer_request waiter active assertionChris Wilson
In defer_request() we start with the request we just unsubmitted (that should be the active request on the gpu) and then defer all of its waiters. No waiter should be ahead of the active request, so none should be marked as active. That assert failed. Of particular note this machine was undergoing persistent GPU resets due to underlying HW issues, so that may be a clue. A request is also marked as active when it is retired, regardless of current queue status, and so this assertion failure may be a result of the queue being completed by the reset and then subsequently processed by the tasklet. We can filter out retired requests here by doing the assertion check after the is-ready check (active is a subset of being ready).

2021-03-15i915/perf: Start hrtimer only if sampling the OA bufferUmesh Nerlige Ramappa
SAMPLE_OA parameter enables sampling of OA buffer and results in a call to init the OA buffer which initializes the OA unit head/tail pointers. The OA_EXPONENT parameter controls the periodicity of the OA reports in the OA buffer and results in starting a hrtimer. Before gen12, all use cases required the use of the OA buffer and i915 enforced this setting when vetting out the parameters passed. In these platforms the hrtimer was enabled if OA_EXPONENT was passed. This worked fine since it was implied that SAMPLE_OA is always passed. With gen12, this changed. Users can use perf without enabling the OA buffer as in OAR use cases. While an OAR use case should ideally not start the hrtimer, we see that passing an OA_EXPONENT parameter will start the hrtimer even though SAMPLE_OA is not specified. This results in an uninitialized OA buffer, so the head/tail pointers used to track the buffer are zero. This itself does not fail, but if we ran a use-case that SAMPLED the OA buffer previously, then the OA_TAIL register is still pointing to an old value. When the timer callback runs, it ends up calculating a wrong/large number of available reports. Since we do a spinlock_irq_save and start processing a large number of reports, NMI watchdog fires and causes a crash. Start the timer only if SAMPLE_OA is specified. v2: - Drop SAMPLE OA check when appending samples (Ashutosh) - Prevent read if OA buffer is not being sampled Fixes: 00a7f0d7155c ("drm/i915/tgl: Add perf support on TGL") Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Ashutosh Dixit <ashutosh.dixit@intel.com> Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210305210947.58751-1-umesh.nerlige.ramappa@intel.com
