[PATCH v3 0/6] Improvements to uc firmare management

[PATCH v3 0/6] Improvements to uc firmare management

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Enhance the firmware table verification code to catch more potential
errors and to generally improve the code itself.

Track patch level version even on reduced version files to allow user
notification of missing bug fixes.

Detect another immediate failure case when loading GuC firmware.

Treat more problems as fatal errors, at least for DEBUG builds.

v2: Use correct patch version number, drop redundant debug print
fail load on table validation error (review by Daniele / CI results).
v3: Fix spelling typos, use a new bool for invalid firmware tables
rather than a status enum (review feedback from Daniele).

[PATCH v3 2/6] drm/i915/guc: Print status register when waiting for GuC to load

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

If the GuC load is taking an excessively long time, the wait loop
currently prints the GT frequency. Extend that to include the GuC
status as well so we can see if the GuC is actually making progress or
not.

[PATCH v3 3/6] drm/i915/uc: Track patch level versions on reduced version firmware files

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

When reduced version firmware files were added (matching major
component being the only strict requirement), the minor version was
still tracked and a notification reported if it was older. However,
the patch version should really be tracked as well for the same
reasons. The KMD can work without the change but if the effort has
been taken to release a new firmware with the change then there must
be a valid reason for doing so - important bug fix, security fix, etc.
And in that case it would be good to alert the user if they are
missing out on that new fix.

v2: Use correct patch version number and drop redunant debug print
(review by Daniele / CI results).

[PATCH v3 4/6] drm/i915/uc: Enhancements to firmware table validation

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The validation of the firmware table was being done inside the code
for scanning the table for the next available firmware blob. Which is
unnecessary. So pull it out into a separate function that is only
called once per blob type at init time.

Also, drop the CONFIG_SELFTEST requirement and make errors terminal.
It was mentioned that potential issues with backports would not be
caught by regular pre-merge CI as that only occurs on tip not stable
branches. Making the validation unconditional and failing driver load
on detecting of a problem ensures that such backports will also be
validated correctly.

This requires adding a firmware global flag to indicate an issue with
any of the per firmware tables. This is done rather than adding a new
state enum as a new enum value would be a much more invasive change -
lots of places would need updating to support the new error state.

Note also that this change means that a table error will cause the
driver to wedge even on platforms that don't require firmware files.
This is intentional as per the above backport concern - someone doing
backports is not guaranteed to test on every platform that they may
potential affect. So forcing a failure on all platforms ensures that
the problem will be noticed and corrected immediately.

v2: Change to unconditionally fail module load on a validation error
(review feedback/discussion with Daniele).
v3: Add a new flag to track table validation errors (review
feedback/discussion with Daniele).

[PATCH v3 5/6] drm/i915/uc: Reject duplicate entries in firmware table

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

It was noticed that duplicate entries in the firmware table could cause
an infinite loop in the firmware loading code if that entry failed to
load. Duplicate entries are a bug anyway and so should never happen.
Ensure they don't by tweaking the table validation code to reject
duplicates.

For full m/m/p files, that can be done by simply tweaking the patch
level check to reject matching values. For reduced version entries,
the filename itself must be compared.

v2: Improve comment (review by Daniele)

[Intel-gfx] [PATCH v3 5/6] drm/i915/uc: Reject duplicate entries in firmware table

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

It was noticed that duplicate entries in the firmware table could cause
an infinite loop in the firmware loading code if that entry failed to
load. Duplicate entries are a bug anyway and so should never happen.
Ensure they don't by tweaking the table validation code to reject
duplicates.

For full m/m/p files, that can be done by simply tweaking the patch
level check to reject matching values. For reduced version entries,
the filename itself must be compared.

v2: Improve comment (review by Daniele)

[PATCH v3 6/6] drm/i915/uc: Make unexpected firmware versions an error in debug builds

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

If the DEBUG_GEM config option is set then escalate the 'unexpected
firmware version' message from a notice to an error. This will ensure
that the CI system treats such occurences as a failure and logs a bug
about it (or fails the pre-merge testing).
