* video: tegra: nvmap: Fix race between write and freeAshish Mhetre2022-01-11
| | | | | | | | | | | | | | | | | | | | | | When NvRmMemWrite() and NvRmMemFree() are called simultaneously on same handle then it could lead to race where dmabuf freed from NvRmMemFree() call could get used by nvmap_get_cachebility() and cause kernel crash. When dmabuf is freed, its exported functions such as get_drvdata() won't be valid anymore and will give error value or NULL. Fix this by checking if get_drvdata() returns error value or NULL and act accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | In case firmware load failed 15340000.vic for whatever reason, we need to reassign pdata->falcon_data NULL else based on check if (pdata->falcon_data), non NULL , code will assume that firmware is loaded properly last time and will go ahead submitting the job, which may result in SMMU-fault.

* tegra: nvmap: Address few inappropriate mixes of integer typesMartin Radev2021-07-09
| | | | | | | | | | | | | | | | | | | | | | | There are possible value truncations when mixing types of different width, e.g. s32 (int), u32, u64. This patch attempts to address such issues in two ways: 1) Manually find and fix error-prone mixing. 2) Prevent creating a handle from an exuberantly large size. The maximum selected size is set to maximum of system memory. This is expected to be small enough that the number of pages fits even in s32. This should offer some future protection in case nvmap starts mixing int and u64 again.

* video: tegra: avoid resetting hub clk rateNaveen Kumar S2021-05-20
| | | | | | | | | | | | | | | | | | | | | | | FMON framework expects nvdisplayhub clock rate to not go below 18.75Mhz. But while disabling head, nvdisplayhub clock is set to 0Hz as part of clearing bandwidth allocations. This causes FMON errors as the rate is lower than minimum rate. Since it is not necessary to reset hub clock rate when disabling the clock, retain existing rate instead of setting it to 0Hz. bug 200722700 Change-Id: Ia63f24ff5d27b94d2bf342d49bfbcd34198131bd Signed-off-by: Naveen Kumar S <nkumars@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvidia/+/2529090 Tested-by: mobile promotions <svcmobile_promotions@nvidia.com> Reviewed-by: svcacv <svcacv@nvidia.com> Reviewed-by: Shu Zhong <shuz@nvidia.com> Reviewed-by: Bibek Basu <bbasu@nvidia.com> Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> GVS: Gerrit_Virtual_Submit

Below are the conditions result in NvRmMemHandle creation - 1) VA: RO and Attr: RW - Don't create NvMap Handle 2) VA: RO and Attr: RO - Create NvMap Handle and set dma_buf_fd as RO 3) VA: RW and Attr: RO - Create NvMap Handle and set dma_buf_fd as RO 4) Mixed VA: RO + RW and Attr: RO - Create NvMap Handle with dma_buf_fd as RO for the whole buffer 5) Mixed VA: RO + RW and Attr: RW - Don't Create NvMap Handle If few pages of the buffer is set as RO and rest as RW, multiple vma are created and vma->end and vma->start doesn't differ by the buffer size, passed to create handle from VA. Hence remove the check. Anyway the check is done in get_user_pages. The change sets dma_buf_fd as RW/RO so that other process should fetch the access permission just by reading f_mode of dma_buf_fd.
