gpu: host1x: Do not setup DMA for virtual devices

2024-04-08T14:52:58Z

The host1x devices are virtual compound devices and do not perform DMA accesses themselves, so they do not need to be set up for DMA. Ideally we would also not need to set up DMA masks for the virtual devices, but we currently still need those for legacy support on old hardware.

gpu: host1x: Skip reset assert on Tegra186

2024-02-22T17:48:06Z

On Tegra186, secure world applications may need to access host1x during suspend/resume, and rely on the kernel to keep Host1x out of reset during the suspend cycle. As such, as a quirk, skip asserting Host1x's reset on Tegra186. We don't need to keep the clocks enabled, as BPMP ensures the clock stays on while Host1x is being used. On newer SoC's, the reset line is inaccessible, so there is no need for the quirk.

gpu: host1x: remove redundant assignment to variable space

2024-02-16T10:51:46Z

The variable space is being initialized with a value that is never read, it is being re-assigned later on. The initialization is redundant and can be removed. Also merge two declaration lines together.

Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the host1x_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

With the previous CDMA stop fix, executing runtime PM ops around system suspend now makes channel submissions work after system suspend, so do that.

gpu: host1x: Stop CDMA before suspending

2023-10-11T20:52:44Z

Before going into suspend, wait all CDMA to go idle and stop it. This will ensure no channel is still active while we enter suspend, and ensures the driver doesn't think that CDMA is still active when coming back from suspend (as HW state has been reset).
