* msm: kgsl: Protect the memdesc->gpuaddr in SVM use casesJordan Crouse2021-01-07
| | | | | | | | | | | When SVM is being used there can only be one GPU address assigned to the memory descriptor. Don't allow the GPU address to be changed after it has been negotiated the first time by a process.

* msm: kgsl: Stop using memdesc->usermemJordan Crouse2021-01-07
| | | | | | | | | | | | | It shouldn't be illegal for memory descriptors to have multiple virtual memory mappings under certain circumstances. If that is the case tracking a single usermem address for each memdesc no longer makes much sense. Get rid of the memdesc->usermem member and use an atomic counter to track mappings instead.

* msm: kgsl: Compare pid pointer instead of TGID for a new processArchana Sriram2020-11-10
| | | | | | | | | | | | | There is a possibility of sharing process_private between two unrelated processes due to PID wrapping. In kgsl_process_private_new(), instead of checking numeric TGID, compare the unique pid pointer of the current process with that of the existing processes in kgsl process list to allow sharing of process_private data judiciously. Also, in all required functions get TGID/PID of a process from its struct pid.

* msm: kgsl: Fix the process sysfs refcountingLynus Vaz2017-11-30
| | | | | | | | | | The kobject used for the process's sysfs node did not provide a release function, so it did not correctly implement the refcounting. Add a release callback so that we keep the process structure valid as long as the kobject is alive. Change-Id: I6db54092ed29ecd4d2f157188a4f1a5fc70f1edf Signed-off-by: Lynus Vaz <lvaz@codeaurora.org>

* msm: kgsl: Return supported page size based on available memory poolsDeepak Kumar2017-09-01
| | | | | | | | | | In case memory pools are supported return the page size as supported only if corresponding memory pool is available. This will increase the usage of memory pool and will reduce the overall allocation time. Change-Id: Iea84a4259b38fe9cb546419dfcbaf0a9666e7ca9 Signed-off-by: Deepak Kumar <dkumar@codeaurora.org>
* msm: kgsl: Limit the frequency of logging on memory allocation failureDeepak Kumar2017-06-30
| | | | | | | | | Excessive logging due to several successive memory allocation failure may cause a watchdog bite. Hence, this change adds ratelimit to logging on memory allocation failure. Change-Id: I8e5d78918a32c48ef7fa587f3dc63cbd1f065d5f Signed-off-by: Deepak Kumar <dkumar@codeaurora.org>
* msm: kgsl: Use per page cache operation instead of bulk cache operationDeepak Kumar2017-05-26
| | | | | | | | | | | | | | For any cache operation, the current code tries to map all pages to the kernel using vmap in case sg table is not available and then performs the requested cache operation. If vmap fails because of memory crunch ioctl just returns failure. This change avoids using vmap and performs per page cache operation even when sg table is not available. This is done to avoid failures because of vmap especially on 32 bit systems. Change-Id: I123b46e6a55a62cbf934ab6a2a49dcd1f0d4c7d4 Signed-off-by: Deepak Kumar <dkumar@codeaurora.org>
* msm: kgsl: Perform cache operation with kernel addressHareesh Gundu2017-04-26
| | | | | | | | | Kernel should never access untrusted pointers directly. If the address is not mapped to kernel, map to kernel address space and perform cache related operation. Change-Id: I433befcde620e51b8ec17954ddb710f6084e0592 Signed-off-by: Hareesh Gundu <hareeshg@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: Fix pagetable member of struct kgsl_memdescJordan Crouse2016-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* msm: kgsl: Do not free gpuaddr range if unmap failsHarshdeep Dhatt2016-09-29
| | | | | | | | | | | | | | | Currently, we free up the gpuaddr range whether unmap succeeds or fails. If it fails and we free up the gpuaddr range, there is a possibility that a later allocation will overlap with this range. Mapping this new range leads to a BUG_ON() in the iommu driver which thinks that we are overwriting an existing mapping. To avoid this, we never free the failing gpuaddr range, effectively removing it from being re-used for any future mappings.

| * msm: kgsl: Add array of page pointers to memdescHarshdeep Dhatt2016-08-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is done to improve the kgsl vmfault routine. Currently, it traverses the sglist to find the faulted page, which takes linear time. By having an array of all the page pointers, this operation will be completed in constant time. Also, allocate sgt only for mapping this memory to the GPU. Since this optimization is not needed for secure/global or imported memory, we will not keep this array but keep the sgt instead.

* msm: kgsl: Use a page pool to reduce allocation timeDeepak Kumar2016-05-05
| | | | | | | | | | | 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.

* msm: kgsl: Refactor MMU/IOMMU supportJordan Crouse2016-03-23
| | | | | | | | | | | | | | | | | | | | | The current MMU code assumes a binary state - either there is a IOMMU or there isn't. This precludes other memory models and makes for a lot of inherent IOMMU knowledge in the generic MMU code and the rest of the driver. Reorganize and cleanup the MMU and IOMMU code: * Add a Kconfig boolean dependent on ARM and/or MSM SMMU support. * Make "nommu" mode an actual MMU subtype and figure out available MMU subtypes at probe time. * Move IOMMU device tree parsing to the IOMMU code. * Move the MMU subtype private structures into struct kgsl_mmu. * Move adreno_iommu specific functions out of other generic adreno code. * Move A4XX specific preemption code out of the ringbuffer code.

* msm: kgsl: Add accounting for memory mapped in userspaceHarshdeep Dhatt2016-03-23
| | | | | | | | | | | For proper memory accounting, a key metric is to know how much memory kgsl allocated for a process and how much of it the process is actually using. This is done by keeping track of memory in our vmfault routines. This information is provided via the process mem file.
