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.

When vm_mmap fail, code jump to OnError with error status and userLogical variable != 0. Then _CMAFSLUnmapUser is called with a invalid virtual address (MdlMap->vmaAddr) and cause panic.

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.

UI operation will very slow when install more applications and enter one by one.

On 8QP we don't have the OVERDRIVE governor, only NOMINAL and UNDERDRIVE. We set the current initial governor to OVERDRIVE, but also display incorrect governor names relative to the clocks assigned in OPP tuples. This patch address this situation by determining which governor should be used at start-up and fixes displaying the governors available for use. This patch also sets the initial clock rate, in case the assigned-clock rates for the cores are different than the ones found in the operating-points (OPP). While this shouldn't be a real use-case this allows testing different OPP tuples to mimic a OPP array for 8QP. Signed-off-by: Marius Vlad <marius-cristian.vlad@nxp.com>
