Somewhat specializaed sub-allocator designed to perform sub-allocation for command buffer not only for current cs ioctl but for future command submission ioctl as well. Patch also convert current ib pool to use the sub allocator. Idea is that ib poll buffer can be share with other command buffer submission not having 64K granularity. v2 Harmonize pool handling and add suspend/resume callback to pin/unpin sa bo (tested on rv280, rv370, r420, rv515, rv610, rv710, redwood, cayman, rs480, rs690, rs880) v3 Simplify allocator v4 Fix radeon_ib_get error path to properly free fence Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
