CL_MEM_USE_HOST_PHYSICAL_ADDR_VIV CL_MEM_USE_HOST_PHYSICAL_ADDR_VIV will use host physical memory directly, logical address is zero. gckOS_UnlockPages will check Logical address and return invalid parameter, that causes memory leak in OpenCL user library, need remove this check.

2019-08-30MA-14512-1 [#imx-1412] Use __GFP_DMA32 to replace CMA LIMIT when ↵Richard Liu
CONFIG_ZONE_DMA32 enable When CONFIG_ZONE_DMA32 kernel configure enabled, use __GFP_DMA32 to ensure allocated memory within 4GB, then dma, cma and gfp allocators all can be used. Previous CMA LIMIT solution has limitation, only CMA allocator can ensure the allocated memory within 4GB and only with CMA LIMIT flag can use CMA allocator, some memory allocate fail due to no CMA limit flag but CMA still has much memory. This patch will back compatible, if enable CONFIG_ZONE_DMA32 use __GFP_DMA32, else keep previous CMA LIMIT logic. 4.19 kernel default enable CONFIG_ZONE_DMA32 by commit "ad67f5a6545f7fda8e", this enable CONFIG_ZONE_DMA32 patch can be cherry-picked to 4.14 kernel. Memory allocate fail cases due to without CMA LIMIT flag (can't use CMA memory) and _GFPAlloc fail due to system does not have enough continue memory: [ 3199.603326] gckOS_AllocatePagedMemoryEx(3171) cmafsl 7ea flag = 13 allocator->capability = c000011 [ 3199.612463] gckOS_AllocatePagedMemoryEx(3171) gfp 7ea flag = 13 allocator->capability = 300001b [ 3199.644893] _GFPAlloc fail, 375, Allocator=ffff80083af76980 Mdl=ffff80082171a000 NumPages=2026 Flags=0x13 [ 3199.712954] gckOS_AllocatePagedMemoryEx(3171) cmafsl 7f8 flag = 1 allocator->capability = c000011 [ 3199.721925] gckOS_AllocatePagedMemoryEx(3171) gfp 7f8 flag = 1 allocator->capability = 300001b [ 3199.735073] _GFPAlloc fail, 375, Allocator=ffff80083af76980 Mdl=ffff80006f6aff00 NumPages=2040 Flags=0x1 Change-Id: I56b93bfa06590bea1e0707c41b40009bd133fecb Signed-off-by: Richard Liu <xuegang.liu@nxp.com>

GPU memory initialization will cause large boot time with 40ms. If GPU memory is allocated from CMA, memset in cma kernel driver, It is not necessary to add duplicated memset in GPU kernel driver. Only GFP allocator need trigger a page fault with a simple write. Signed-off-by: Xianzhong <xianzhong.li@nxp.com>
2019-02-12MGS-4151-6 [#imx-1166] merge register read fix for clock-offXianzhong
CL165804 fix read register when internal clock off 1. For shared IRQ, read register may be called and that's not our irq. 2. In some condition, when ISR handled normal FE/PE, PM thread could trun off internal clock before ISR read register of async FE. And then IRQ handler will call read register with internal clock off. So here we need to skip read in such case. This is simple fix. cherry-pick patch: 6.2.4.p3-0019-CL165804-fix-read-register-when-internal-clock-off-1 Signed-off-by: Xianzhong <xianzhong.li@nxp.com>
