Insert few more failure points into firmware fetch procedure to check use of the wrong blob name or use of the mismatched firmware versions. Also update some messages (remove ptr, duplicated infos) and stop treating all fetch errors as missing firmware case. v2: update log levels (Chris) Signed-off-by:

WOPCM programming error might be due to inserted earlier probe failure that could affects HuC firmware loading and thus impacts result of WOPCM partitioning that would be now incompatible with previously programmed values. Signed-off-by:

No need to define it globally as we're only using it in wopcm.c Signed-off-by:
-
Michal Wajdeczko authored
For meaningful WOPCM partitioning we need GuC (and optionally HuC) firmware size(s) and we shouldn't just rely on GuC support flag, as we might fail to fetch GuC firmware and it's size will be 0 and all calculations will be just wrong/useless. Signed-off-by:

When we failed to fetch GuC firmware there is no point in fetching HuC firmware as we will not be able to use it without working GuC. Signed-off-by:
-
Michal Wajdeczko authored
There is no point in selecting HuC firmware if GuC is unsupported or it was already disabled, as we need GuC to authenticate HuC. While around, make uc_fw_init_early work without direct access to whole i915, pass only needed platform/rev info. Signed-off-by:

The oa object manages the oa buffer and must be allocated when the user intends to read performance counter snapshots. This can be achieved by making the oa object part of the stream object which is allocated when a stream is opened by the user. Attributes in the oa object that are gen-specific are moved to the perf object so that they can be initialized on driver load. The split provides a better separation of the objects used in perf implementation of i915 driver so that resources are allocated and initialized only when needed. v2: Fix checkpatch warnings v3: Addressed Lionel's review comment v4: Rebase v5: Fix rebase/merge issue with ratelimit_state_init Signed-off-by:

Use the same mechanism to determine if a backend engine exists for a uabi mapping as used internally. Signed-off-by:
-
Chris Wilson authored
During engine setup, we may find that some engines are fused off causing a misalignment between internal names and the instances seen by users, e.g. (I915_ENGINE_CLASS_VIDEO_DECODE, 1) may be vcs2 in hardware. Normally this is invisible to the user, but a few debug interfaces (and our own internal tracing) use the original HW name not the name the user would expect as formed from their class:instance tuple. Replace our internal name with the uabi name for consistency with, for example, error states. v2: Keep the pretty printing of class name in the selftest Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=111311Signed-off-by:

We don't really want to use VM_IO for our GGTT mmaps (it implies that the mmap contains memory mapped registers, which we do not expose) yet I overzealously added it to an assert just because that's how we always had setup the vma. Signed-off-by:

Increase abstraction of display suspend/resume operations by providing higher level functions, and hiding the details inside intel_display_power.c. v2: Make checkpatch happy: - braces {} are not necessary for single statement blocks v3: Also move hsw/bdw PC8 sequences since they are related to display PM anyways.

Everything about the file is about display, and mostly about types related to display. Move under display/ as intel_display_types.h to reflect the facts.

Since commit 301efe96 ("drm/i915/uc: Don't fail on HuC firmware failure") we can continue driver load after error during HuC firmware load or authentication, but we could still fail on any error during early HuC initialization.
