2010-04-16Correct the Solaris definitions of atomic_add & atomic_decAlan Coopersmith
The #defines added in 966c9907c040b4fe4b288b4a9d82598797aee743 were mapping these to functions that don't exist. Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>
2010-03-17libdrm_radeon: Optimize cs_gem_reloc to do less looping.Pauli Nieminen
bo->referenced_in_cs is checked if bo is already in cs. Adding and removing reference in bo is done with atomic operations to allow parallel access to a bo from multiple contexts. cs->id generation code quarentees there is not duplicated ids which limits number of cs->ids to 32. If there is more cs objects rest will get id 0. V2: - Fix configure to check for atomics operations if libdrm_radeon is only selected. - Make atomic operations private to libdrm. This optimization decreases cs_write_reloc share of torcs profiling from 4.3% to 2.6%. Tested-by: Michel Dänzer <michel@daenzer.net> Signed-off-by: Pauli Nieminen <suokkos@gmail.com>
