* gpu: nvgpu: Reload ZBC values on rail gate exitTerje Bergstrom2015-03-18
| | | | | | | | | | | When exiting rail gate, we reloaded default ZBC values. The correct behavior is to reload the values. Bug 1447255 Change-Id: I7aad3586dda91a91a3629062a27001af281b955e Signed-off-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-on: http://git-master/r/418346
* gpu: nvgpu: gm20b: fix compression sharingKevin Huang2015-03-18
| | | | | | | | | | | | | | | | For GM20B alone, the LTC count is already accounted for the HW logic for the CBC base calculation from the postDivide address. So SW doesn't have to explicity divide it by the LTC count in the postDivide address calculation.

* gpu: nvgpu: Implement ELPG flush for gm20bTerje Bergstrom2015-03-18
| | | | | | | | | | | ELPG flush is initiated from a common broadcast register, but must be waited on via per-L2 registers. Split gk20a and gm20b versions of the flush.

* video: tegra: gk20a: remove redundant codeBo Yan2015-03-18
| | | | | | | | | | | | | gk20a_ltc_init_comptags and gk20a_ltc_clear_comptags are defined in ltc_gk20a.c, gm20b has its own init/clear functions, so remove these two from ltc_common.c change nvhost_allocator_init to gk20a_allocator_init, this is a left-over after rebase, just like the above 2 function definitions, so fix it.

* gpu: nvgpu: Allow mapping backing storeArto Merilainen2015-03-18
| | | | | | | | | | | Backing store sgt needs to be mapped to gpuva to enable CDE swizzling. This patch adds necessary code to create sgt during initialisation so that the sgt is available when needed.
