Subject: drm/i915/psr: Try to program link training times correctly
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
The default of 0 is 500us of link training, but that's not enough for
|
||||
some platforms. Decoding this correctly means we're using 2.5ms of
|
||||
link training on these platforms, which fixes flickering issues
|
||||
associated with enabling PSR.
|
||||
|
||||
v2: Unbotch the math a bit.
|
||||
|
||||
v3: Drop debug hunk.
|
||||
|
||||
v4: Improve commit message.
