2014-12-18MGS-374 [#1500] fix GPU kernel debugfs crash issueXianzhong
this crash issue is caused by kernel NULL pointer when access GPU database, GPU database is shared by all kernels, it can be queried with any valid kernel. this patch will find the valid kernel pointer to avoid GPU kernel crash. the crash backtrace with 'cat /sys/kernel/debug/gc/vidmem' on i.mx6sl: [<80480600>] (gckKERNEL_FindDatabase+0x8/0xec) from [<80478db0>] (vidmem_show+0x2c/0x60) [<80478db0>] (vidmem_show+0x2c/0x60) from [<800e4d5c>] (seq_read+0x1dc/0x47c) [<800e4d5c>] (seq_read+0x1dc/0x47c) from [<800c7164>] (vfs_read+0x98/0x144) [<800c7164>] (vfs_read+0x98/0x144) from [<800c77c4>] (SyS_read+0x3c/0x78) [<800c77c4>] (SyS_read+0x3c/0x78) from [<8000e080>] (ret_fast_syscall+0x0/0x30) Date: Dec 18, 2014 Signed-off-by: Xianzhong <b07117@freescale.com> Acked-by: Jason Liu (cherry picked from commit 5b59e9d67ee1ce25e43fcb8934fcf0c75abfd0e3)
2014-12-12MLK-9881: mxc: asrc: fix dma task timeout issue when use 3 instance.Shengjiu Wang
1. Watermark level in sdma use byte as its unit. but asrc driver use word, there is mismatch between them. Here fix this issue and sdma can work more efficiency. 2. Enlarge the larst_period_size, when use small size, for some case, the dma task will timeout, because sdma has no much data for output. Signed-off-by: Shengjiu Wang <shengjiu.wang@freescale.com>

2014-08-27ENGR00301095 gpu:gpu hang when dma memory is used upLoren Huang
When dma zone memory used up, gckOS_AllocateCMAMemoryFSL() will try to free non paged memory cache and allocate again. Such operation will cause twice memory mutex request and cause gpu driver hang. The solution is free the memory mutex at first before trying to free non paged memory cache.

2014-08-27ENGR00308066 [#1091]Use spinlock_irqsave instead of spinlock in gpuLoren Huang
Gpu kernel driver used spinlock in inerrupt context for debug purpose. So when enabled debug mode in gpu kernel driver, it may cause gpu kernel driver deadlock. Changed spinlock to spinlock_irqsave to resolve this issue. Patch from vivante. Date: Apr 11, 2014 Signed-off-by: Loren Huang <b02279@freescale.com>
