Hi Peter,
Here's the 2nd go at the AUX area. This covers pretty much what I need
for Intel PT buffer management.
Alexander Shishkin (6):
perf: add data_{offset,size} to user_page
perf: support high-order allocations for AUX space
perf: add a capability for AUX_NO_SG pmus to do software double
buffering
perf: add a pmu capability for "exclusive" events
perf: add api for pmus to write to AUX space
perf: add AUX record
Peter Zijlstra (1):
perf: add AUX area to ring buffer for raw data streams
