* | msm: kgsl: Enable Content Protection for A512 GPURajesh Kemisetti2017-01-02
|/ | | | | | | | Enable CPZ feature for A512 GPU on sdm660. This is required to process secure conent by GPU. Change-Id: Iaaedde4e56e331379be0b44b23527df0d5807f55 Signed-off-by: Rajesh Kemisetti <rajeshk@codeaurora.org>
* msm: kgsl: Do a midframe sampling of power stats if enabledPrakash Kamliya2016-12-22
| | | | | | | | | | | | Currently we sample power stats at the expiry of cmdbatch. In cases where cmdbatch takes a long time to finish the job, it delays power stats sampling, in effect it delays DCVS decision for changing the frequency. Do a midframe power stats sampling and feed it to DCVS if it is enabled. Change-Id: I547d792b38649aa1d60525b0dc335791b37989fd Signed-off-by: Prakash Kamliya <pkamliya@codeaurora.org>

This will fix kgsl driver probe failure for without gpu mempool configuration devices. Change-Id: I3142a5d2e13ed40f643c91594fd868c37620ce54 Signed-off-by: Hareesh Gundu <hareeshg@codeaurora.org>

| * msm: kgsl: Add Bind objects to dispatcher draw queueTarun Karra2016-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kgsl_ioctl_gpu_sparse_command() is added to for user to specify list of binds/unbinds for a memory entry and syncpoints they depend on. If user specifies both create a sync object for syncpoints and bind object for binds/unbinds and add them to dispatcher draw queue. Sync object should be inserted before the bind object in the draw queue. Once the bind object reaches the head of draw queue the corresponding binds/unbinds are performed. kgsl_ioctl_gpu_sparse_command() only accepts commands from context created with flag KGSL_CONTEXT_SPARSE, commands from all other context types will return an error.

| * msm: kgsl: Reserve a context ID slot but don't populate immediatelyJordan Crouse2016-11-29
| | | | | | | | | | | | | | | | | | | | | | When creating a context allocate an ID but don't populate the slot with the context pointer until we are done setup up the rest of the process. This avoids a race if somebody tries to free the same identifier before the create operation is complete.

* | msm: kgsl: Update ringbuffer timer when preemption completesHarshdeep Dhatt2016-11-29
|/ | | | | | | | | | | | | | | | Ringbuffer timer should always be reset whenever we finish preempting to that ringbuffer. Currently, there is a case where wptr in the hardware and the kgsl are identical and thus the timer isn't reset. Reset the timer regardless if they are identical or not. There is one special case when we shouldn't reset the timer. This happens when we try to figure out next ringbuffer to preempt but the next ringbuffer is the same one as current. In that case, if nothing new got submitted to this ringbuffer, then don't reset the timer. Change-Id: I6b5aea46f1769021b39ba6e135bef780719a92e7 Signed-off-by: Harshdeep Dhatt <hdhatt@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | If one is mapping anonyomous user memory in the GPU with SVM enabled we want to try to accommodate that request if possible. The memory address was being set up correctly in the memory descriptor but the GPU address was getting tripped up when getting mapped in the process. This is because the memory should be treated like SVM memory so it needs to be registered in the memory tree and the rest of the path needs to accept the address.

| | | | | | | | | | | | | | | | | | | | | | | | | | memdesc->pagetable is supposed to help ensure that memory gets unmapped before it is freed, but the pagetable member is being populated at create time not when the buffer gets mapped. This forces the developer to ensure that the same pagetable is used for both the create and map step. Instead, assign the pagetable member when it is first used (to get a GPU address) and put it away when the GPU address is released.

When attaching a dma_buf to kgsl, use the dma_buf_attachment's (void*)priv to point back to the kgsl_mem_entry. This makes it possible to iterate through all attachments on a dma_buf and gather statistics from each kgsl_mem_entry associated with the dma_buf.

If userspace in an IOCTL incorrectly sends an unaligned address at the boundary of device type memory mapping to kernel, there will be a fault because kernel goes ahead and reads the device type memory with unaligned access. To overcome such issues, change device-type memory mapping to Normal-noncached wherever it is possible.

Outputing all of them as a single debugfs seq_file record takes twice as long as necessary because seq_file must retry higher order page allocations for the output buffer until it is large enough to hold all mem entries. Additionally, process_mem_print() currently holds the spinlock private->mem_lock during this process. This is too much time to disable interrupts, and prevents locking mutex in print_mem_entry. Change the kgsl_mem_entry debugfs functions to output one entry at a time. Then the seq_file only need to kmalloc one page regardless of the number of kgsl_mem_entries.
