Rebased on nightly, including recent review updates (CI wasn't happy picking up the replies updating individual patches). This also reverts back to pinning the context upfront when opening a stream for a single context, instead of hooking into pinning and updating OACONTROL on the fly. Chris has repeatedly suggested he'd prefer to have the driver work with an upfront pin, as it used to, instead of with the hook. It was changed last time based on feedback considering some concern with the shrinker. At least from inspection it does /seem/ safe to assume a pinned vma will reliably block the shrinker from freeing ctx pages and the shrinker itself doesn't unpin things. I'm not fully certain of the interaction with the _gem.c _context_lost() code path which aims to unpin last_context. At least the code is a little simpler this way, so maybe if Daniel is happy that his original concern was overly cautious (or no longer an issue with the latest code), then this change is ok. - Robert Robert Bragg (11): drm/i915: Add i915 perf infrastructure drm/i915: rename OACONTROL GEN7_OACONTROL drm/i915: return EACCES for check_cmd() failures drm/i915: don't whitelist oacontrol in cmd parser drm/i915: Add 'render basic' Haswell OA unit config drm/i915: Enable i915 perf stream for Haswell OA unit drm/i915: advertise available metrics via sysfs drm/i915: Add dev.i915.perf_stream_paranoid sysctl option drm/i915: add oa_event_min_timer_exponent sysctl drm/i915: Add more Haswell OA metric sets drm/i915: Add a kerneldoc summary for i915_perf.c drivers/gpu/drm/i915/Makefile | 4 + drivers/gpu/drm/i915/gvt/handlers.c | 2 +- drivers/gpu/drm/i915/i915_cmd_parser.c | 45 +- drivers/gpu/drm/i915/i915_drv.c | 9 + drivers/gpu/drm/i915/i915_drv.h | 155 +++ drivers/gpu/drm/i915/i915_oa_hsw.c | 752 ++++++++++++++ drivers/gpu/drm/i915/i915_oa_hsw.h | 38 + drivers/gpu/drm/i915/i915_perf.c | 1689 ++++++++++++++++++++++++++++++++ drivers/gpu/drm/i915/i915_reg.h | 340 ++++++- include/uapi/drm/i915_drm.h | 133 +++ 10 files changed, 3127 insertions(+), 40 deletions(-) create mode 100644 drivers/gpu/drm/i915/i915_oa_hsw.c create mode 100644 drivers/gpu/drm/i915/i915_oa_hsw.h create mode 100644 drivers/gpu/drm/i915/i915_perf.c -- 2.10.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
