Subject: gpu: pvr: no need to delay queue processing in SGXPostActivePowerEvent
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2a04faaa37a9d2f951edd138128dcc351ff8c1d0;p=sgx.git

gpu: pvr: no need to delay queue processing in SGXPostActivePowerEvent

At the moment processing of the command queue is delayed in case
SGXPostActivePowerEvent in the HW interrupt code path. This would be
only justified in case of being in interrupt context. This might have
been the case at one point in the history, but now HW interrupts
result in a work scheduled and thus calling the queue processing
function is safe in all cases.
