2021-06-08arm64: smccc: Support SMCCC v1.3 SVE register saving hintMark Brown1-0/+4
SMCCC v1.2 requires that all SVE state be preserved over SMC calls which introduces substantial overhead in the common case where there is no SVE state in the registers. To avoid this SMCCC v1.3 introduces a flag which allows the caller to say that there is no state that needs to be preserved in the registers. Make use of this flag, setting it if the SMCCC version indicates support for it and the TIF_ flags indicate that there is no live SVE state in the registers, this avoids placing any constraints on when SMCCC calls can be done or triggering extra saving and reloading of SVE register state in the kernel. This would be straightforward enough except for the rather entertaining inline assembly we use to do SMCCC v1.1 calls to allow us to take advantage of the limited number of registers it clobbers. Deal with this by having a function which we call immediately before issuing the SMCCC call to make our checks and set the flag. Using alternatives the overhead if SVE is supported but not detected at runtime can be reduced to a single NOP.

Commit 4782c0a5dd88 ("clk: tegra: Don't deassert reset on enabling clocks") removed some legacy code for handling resets on Tegra from within the Tegra clock code. This exposed an issue in the Tegra20 slink driver where the SPI controller reset was not being deasserted as needed during probe. This is causing the Tegra30 Cardhu platform to hang on boot.

It is not necessary to put free_iova_mem() inside of spinlock/unlock iova_rbtree_lock which only leads to more completion for the spinlock. It has a small promote on the performance after the change. And also rename private_free_iova() as remove_iova() because the function will not free iova after that change.

The CC submodule is a part of the atmel-isc pipeline, and stands for Color Correction. It is used to apply gains and offsets to the chroma (U, V) components of the YUV elements. Implement the CC submodule initialization, as a product specific function, which currently configures the neutral point in color correction.

Commit d25f6ead162e ("iommu/arm-smmu-v3: Increase maximum size of queues") expands the cmdq queue size to improve the success rate of concurrent command queue space allocation by multiple cores. However, this extension does not apply to evtq and priq, because for both of them, the SMMU driver is the consumer. Instead, memory resources are wasted. Therefore, the queue size of evtq and priq is restored to the original setting, one page.

2021-06-08iommu/arm-smmu-v3: Add stall support for platform devicesJean-Philippe Brucker3-15/+283
The SMMU provides a Stall model for handling page faults in platform devices. It is similar to PCIe PRI, but doesn't require devices to have their own translation cache. Instead, faulting transactions are parked and the OS is given a chance to fix the page tables and retry the transaction. Enable stall for devices that support it (opt-in by firmware). When an event corresponds to a translation error, call the IOMMU fault handler. If the fault is recoverable, it will call us back to terminate or continue the stall. To use stall device drivers need to enable IOMMU_DEV_FEAT_IOPF, which initializes the fault queue for the device.
