| * | gpu: host1x: Make host1x_context_device_bus_type constant | Kunwu Chan | 2024-08-29 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | 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_context_device_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

| * | gpu: host1x: Add context bus | Mikko Perttunen | 2022-06-01 | 1 | -0/+15 |
| The context bus is a "dummy" bus that contains struct devices that correspond to IOMMU contexts assigned through Host1x to processes. Even when host1x itself is built as a module, the bus is registered in built-in code so that the built-in ARM SMMU driver is able to reference it.
