2016-05-18msm: kgsl: Port GPU bus dcvs to kernel 4.4Oleg Perelet
Port GPU dcvs from kernel 3.18 to kernel 4.4. CRs-Fixed: 1013343 Change-Id: Ide662b12aa59effa541febcd758426e72b4a1b12 Signed-off-by: Oleg Perelet <operelet@codeaurora.org>
2016-05-11msm: kgsl: Add property to determine GPU bitnessSunil Khatri
Add the property to determine GPU bitness which is used by the clients via KGSL ioctl. Certain clients of KGSL such as Open-CL driver need to know explicitly about the GPU mode. Change-Id: I77523d7816edb9776014aaf3aa85321af0d20aaf Signed-off-by: Sunil Khatri <sunilkh@codeaurora.org>
2016-05-11msm: kgsl: Use the crash dumper to read HLSQ/shader memory on 5XXJordan Crouse
The host AHB aperture for reading the HSLQ/SP/TP and shader memory blocks might be blocked on A5XX targets so use the CP crash dump utility to read them instead. Downside if the crashdumper goes boom we'll have to skip those registers in the fallback. Change-Id: Ic0dedbad3c7b485c696198bdfcb78d45e929ec22 Signed-off-by: Jordan Crouse <jcrouse@codeaurora.org>

2016-05-11msm: kgsl: Do not allocate memory for profiling and sync commandsSunil Khatri
Do not allocate memory for IB descriptors for commands of types profiling buffers, sync and markers. This fixes the memory leak due to allocation of memory for such commands and these were never freed.

2016-05-11msm: kgsl: Add 1M and 8K pools to the allocatorShrenuj Bansal
This change includes the below: - Add 1M and 8k pools and structure the allocator to use all pools from the largest page to the smallest - Reserve a set number of pages for each of these pools at init time - When allocating, use the reserved pools and then fall back to allocating from system memory using only 8k and 4k pages - Remove maximums on the pool sizes - Zero the memory when we create the pool initially and add pages back to the pool on free CRs-Fixed: 995735 Change-Id: I9440bad62d3e13b434902f167c9d23467b1c4235 Signed-off-by: Shrenuj Bansal <shrenujb@codeaurora.org>
2016-05-05msm: kgsl: Remove harmless preemption log messageHarshdeep Dhatt
This message is logged when we receive a preemption interrupt after we have already detected that preemption has been finished in hardware by reading the preemption status register.

2016-05-05msm: kgsl: Dump 64KB of preemption record in snapshotHarshdeep Dhatt
Dumping only the ctxt_record structure in a snapshot is not enough. For a more meaningful snapshot, dump 64KB of preempt record. Also, move the code to device specific snapshot function. Change-Id: I43e08ccefbf2d3911191b2aad5168979956e1626 Signed-off-by: Harshdeep Dhatt <hdhatt@codeaurora.org>

2016-05-05msm: kgsl: Don't spam kmsg due to invalid IOCTL requestsCarter Cooper
When the IOCTL is called with invalid data, don't log to kmsg. The returned error code should be enough to tell the UMD what they did wrong. CRs-Fixed: 987074 Change-Id: Iae380e0f44dd53bee8ff4cec347a6b9a632b1f84 Signed-off-by: Carter Cooper <ccooper@codeaurora.org>
2016-05-05msm: kgsl: Remove superfluous NULL checks when reading timestampsCarter Cooper
There is no way for the UMD to pass in NULL pointers for reading timestamps. The KGSL driver also always has valid pointers for storing the readpointer. Remove the checks that are not needed. Change-Id: Id5f244a57a2b991a10b603ef7236193d4282fd0f Signed-off-by: Carter Cooper <ccooper@codeaurora.org>

2016-05-05msm: kgsl: Use a page pool to reduce allocation timeDeepak Kumar
Use a mempool to reduce the allocation time. When memory allocated from pages is freed, put it in a page pool. At allocation time, try to allocate from the page pool before getting pages from the system. Make sure that the pool does not grow too big by enforcing a maximum limit.

2016-04-13msm: kgsl: Pass correct buffer size for mapping gpuobj user memoryTarun Karra
Current code incorrectly specifies buffer size as 0 for mapping gpuobj user memory. This causes the map to fail because buffer size is expected to be a non zero value. Fix this by passing the correct size of the buffer to be mapped. CRs-Fixed: 995378 Change-Id: I1a9aeb3f1dd67f014847322e5b14cba8775a82a4 Signed-off-by: Tarun Karra <tkarra@codeaurora.org>
2016-04-13msm: kgsl: Fix gpudev NULL dereference in adreno_removeHareesh Gundu

2016-04-13msm: kgsl: verify user memory permissions before mapping to GPU driverTarun Karra
For user memory of type KGSL_USER_MEM_TYPE_ADDR mapped to GPU driver verify permissions and map GPU permissions same as CPU permissions. If elevated permissions are requested return an error to prevent privilege escalation. Without this check user could map readonly memory into GPU driver as readwrite and gain elevated privilege. Write permissions check is currently inverted causing readonly user pages to be mapped as readwrite in GPU driver. Fix this check to map readonly pages as readonly.

2016-04-13msm: kgsl: Correct the order of preemption packetsHarshdeep Dhatt
Current order: IB1 batch, timestamp writes, SRM=NULL, CP_YIELD_ENABLE, CP_CONTEXT_SWITCH_YIELD Correct order: IB1 batch, SRM=NULL, CP_YIELD_ENABLE, timestamp writes, CP_CONTEXT_SWITCH_YIELD Reason: if preemption is initiated after the last checkpoint but before SET_RENDER_MODE == NULL is executed, all of the PM4s starting at the preamble of the check point will be replayed up to the SRM == NULL, including an attempt to re-timestamp/ re-retire the last batch of IBs. If what was intended here was to make sure that the IB batch would be retired once then the SET_RENDER_MODE == NULL and CP_YIELD_ENABLE should be placed immediately after IB_PFE packets and before the time stamping PM4 packets in the ring buffer.

2016-03-25msm: kgsl: Attach mem_entry once we have valid GPU addressRajesh Kemisetti
kgsl_mem_entry_attach_process() adds new entry to the mem_idr list without really having a valid GPU address. This new entry can be used by other thread with GPUADDR_IN_MEMDESC() and destroy it.

Allocate guard page when the first buffer is mapped into the IOMMU. This also ensures that the guard page gets allocated if the guard page mmu feature is enabled. CRs-Fixed: 988093 Change-Id: Id97492707463a1f15a4bf1c67b9c0f03214e6283 Signed-off-by: Hareesh Gundu <hareeshg@codeaurora.org>
2016-03-25msm: kgsl: Fix race condition during mem_entry detachRajesh Kemisetti
kgsl_mem_entry_detach_process() makes gpuaddr to NULL and then removes the entry from mem_idr list. Sometimes this can cause kgsl_sharedmem_find() to return the same entry for a different gpuaddr/thread if it satisfies GPUADDR_IN_MEMDESC(). To avoid this, first remove the entry from mem_idr list and proceed with unmap/untrack calls.

2016-03-25msm: kgsl: Standardize ringbuffers in the snapshotJordan Crouse
'start' and 'stop' in the snapshot ringbuffer header are supposed to be the dword offset that the data starts and stops at respectively. For the current ringbuffer which is parsed 'start' and 'stop' are equal to the CP wptr but all other ringbuffers are just dumped from start to finish so 'start' and stop' should be 0 and KGSL_RB_DWORDS. And having said that, why are we bothering to make the current ringbuffer special anyway? In every case we are dumping the entire ringbuffer so we might as well dump it in order. While messing about in this code go a few more steps to make sure that we don't dump the same ringbuffer more than once.

Disable the guardpage workaround for A5x and instead selectively suppress pagefaults. Suppress read pagefaults that are likely caused due to UCHE overfetches.

2016-03-25msm: kgsl: Change the active context trackerPrakash Kamliya
The active context tracker that we bolted on the side of the dispatcher was designed mainly to see if there was 1 OR more than 1 active context, not much more than that. Since it is apparent that we'll need to track up to 4 contexts and possibly more later the algorithm needs to change. The new algorithm puts all active contexts on a linked list - every time a context is used it is popped from the list and put on the tip with an updated time. To count the number of active contexts walk the list until you get a context with an active time older than you are looking for. You also can do other magic on the context, like see if it matches up with a given command queue.
