* | msm: kgsl: Correct memory type update in IOCTL_KGSL_GPUOBJ_SET_INFODeepak Kumar2018-03-02
| | | | | | | | | | | | | | | | | | A bad user can pass memory type parameter value greater than 255. Limit the memory type value to valid range before updating memory descriptor flags to avoid incorrect flag update.

* msm: kgsl: Prevent race condition when freeing memoryDeepak Kumar2018-02-21
| | | | | | | | | | Add a check to set the pending_free flag if it is not already set before freeing sparse memory entry. This is required to prevent multiple ioctl threads from freeing the same sparse memory entry. Change-Id: I4e2bbe6fcd98c58d36340c4f87cdff27fc1de22e Signed-off-by: Deepak Kumar <dkumar@codeaurora.org>

* | msm: kgsl: Add a check for valid frequency of RBBM timer clockArchana Obannagari2018-02-15
|/ | | | | | | | | | rbbmtimer_clk hardwired fixed XO frequency 19.2Mhz. clock_round_rate() for RBBM timer clock fails with -EPERM as it is fixed. So added a check to make sure that rbbmtimer_clk clk_set_rate() has valid frequency. This avoids warning message in the driver log.

* msm: kgsl: Update global memory base to 0XFC000000 for 64bit kernelDeepak Kumar2018-01-30
| | | | | | | | | | | | KGSL memstore GPU address should be 32bit value for user mode graphics driver to successfully mmap device memstore. Move global memory base to 0XFC000000 from 0X100000000 for 64bit kernel to allow user mode graphics driver to successfully mmap memstore.

* msm: kgsl: Move global memory region to 0x100000000Deepak Kumar2018-01-23
| | | | | | | | | | | | | | | On a 64bit kernel, a 32bit user application is not restricted to 3GB limit of virtual memory. It is allowed to access complete 4GB range. Move global memory region to 0x100000000 outside of 32bit range on 64bit kernel to increase the virtual memory range for a 32bit application running on a 64bit kernel. This will also move secure memory region to 0xF0000000. Change-Id: I017ac0c052b4d9466f9f1a66af4a83f0636450cb Signed-off-by: Deepak Kumar <dkumar@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | There is no check before cache ops if the memory is marked secure. This leads to stage 2 pagefault if a secure memory is passed to IOCTL_KGSL_GPUMEM_SYNC_CACHE ioctl because kernel is not allowed to do cache ops on secure memory.
