Subject: [PATCH] media/gpu/vaapi: Fix the VA_CHECK_VERSION
|
|
|
|
commit 6f1309ef8fe109 ("media/gpu/vaapi: Relax the version
|
|
check for VA-API") added the VA_CHECK_VERSION to relax the
|
|
VA-API version check. But it still does the same thing as
|
|
the previous check. VA_CHECK_VERSION will return 'true', only
|
|
when the VA-API version is greater than or equal to the
|
|
parameters passed to it. So in this case when the major and
|
|
minor version were passed from vaInitialize() output, it did
|
|
the same strict check as earlier. When trying to update libva
|
|
to a newer version, there will still be a mismatch, since
|
|
vaInitialize() would return the updated/newer libva version
|
|
installed on the system, but the chromium would still be built
|
|
with older version (libva-2.1.0 as of now).
|
|
To fix this and actually relax the check, make sure the system
|
|
version of libva is greater than the libva version with which
|
|
the browser is built, since libva is backward compatible. This
|
|
will allow any future libva updates without breaking existing code.
|
