Subject: [PATCH] dcn20_resource: use GFP_ATOMIC in validate_bandwidth_internal
|
|
||||||
|
|
||||||
GFP_KERNEL may and will sleep, and this is being executed in
|
|
||||||
a non-preemptible context; this will mess things up since it's
|
|
||||||
called inbetween DC_FP_START/END, and rescheduling will result
|
|
||||||
in the DC_FP_END later being called in a different context (or
|
|
||||||
just crashing if any floating point/vector registers/instructions
|
|
||||||
are used after the call is resumed in a different context).
