2010-11-06nvmap: Improved compaction algorithm implementedKirill Artamonov
Fast compaction algorithm: for every free block from the beginning of CO, try to reallocate block before and after the free block. Once enough free space for requested allocation is freed, return. Full compaction triggers if fast one fails: it works like fast one but also uses block moving algorithm which doesn't require extra CO memory. It compacts all heap, merging as much free space as possible. Also fixed few bugs. bug 740842 bug 746972 (cherry picked from commit 171edd17a191c8a4a4f9a8434dec796089cda141) Change-Id: I40ec2c49a3c3f37fd7149e8123eda59da4caef39 Reviewed-on: http://git-master/r/10149 Reviewed-by: Kirill Artamonov <kartamonov@nvidia.com> Tested-by: Kirill Artamonov <kartamonov@nvidia.com> Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

Drastic reduction of ACM timeout to 2ms (from 1sec) resulted in power increase for NV omxplayer video-playback (bug 738557). The reason is that short-term scheduling does not provide enough idle time for LP2 state (CPU powered down). On the other hand, 1 sec timeout prevented core voltage scaling during Android music audio-playback (bug 735111). Hence, tuned ACM timeout to 25ms.

When user doesn't use default heap policy and selects GART or carveout allocation, automatic single-page-to-sysmem rule doesn't work. Because of broken rule many single page allocations go to GART and carveout. The fix adds sysmem bit to heap mask when allocation is single page and GART or carveout is present in heap mask. bug 730124 bug 731923 (cherry picked from commit 3ca9989c922420a57215d297189738a0464c4073) Change-Id: I2ea8018ae5ed9d31e90659479d0e44052ebf9431 Reviewed-on: http://git-master/r/6701 Reviewed-by: Kirill Artamonov <kartamonov@nvidia.com> Tested-by: Kirill Artamonov <kartamonov@nvidia.com> Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>
