Fix kernel crash issue meet when do 720p Camera recording on WFD source side, the crash is related with timer schedule, fixed by add protection code in gckOS_StartTimer function.

2013-10-23ENGR00278452 PU: fix system hang if run Audio loop testRobin Gong
cpufreq and pu power management will oprate the same register, it looks should keep them operating in order not concurrent. Then use the cpufreq mutex in xPU driver to make sure. Another code bug is in pu power management which base regulator framework, we set the reister directly not regulator, then there is the chance set_volatage will miss the chance if this time voltage setting as the last time setting before PU disable, but we have to do this, so add regulator_sync_voltage to force sync the voltage setting. The drawback is setting twice... Note: This patch is temporary and supposed to be replaced it once we find the root cause. Signed-off-by: Robin Gong <b38343@freescale.com> Acked-by: Jason Liu
2013-09-18ENGR00278701 use alloc_pages instead of alloc_pages_exactRichard Liu
alloc_pages_exact is added by Vivante in gpu git commit e3debfdf4c3f29519ee66d60ac9b5e4db4c41026. alloc_pages_exact is more easy make memory fragment, video playback and camera recording case need large physical continue memory, using alloc_pages_exact will easy make memory fragment and no large physical continue memory, it will impact video playback and camera case.

Add this account to let real large memory user get killed if going to background eg, the "angry bird Space" will acquire 68,215,360 GPU memory for 1-6 toll-gate.

2012-07-20ENGR00213170-2 [MX6SL] Enable GPU driverLarry Li
Use allocated GPU resource to enable GPU. Memroy address on imx6sl board starts from 0x80000000 and GC320 can access [baseAddress, baseAddress + 2G) only without MMU. So to make GC320 work, baseAddres must be set to 0x80000000, and all address sent to GC320 must be a offset to baseAddress. GC355 doesn't need this baseAddress, that means it needs a real physcial adress, rather than the offset to baseAddress. Original code always change phsysical address to 'offset' before use it, no matter it is used by GC355 or GC320, so only one of them can work. Solution is to move address adjustion to arch specific part. So each core can get what it wants. Signed-off-by: Larry Li <b20787@freescale.com> Acked-by: Lily Zhang
