597b89d3 - gpu: host1x: Add context bus

Mon, 16 May 2022 08:52:51 +0000

gpu: host1x: Add context busThe context bus is a "dummy" bus that contains struct devices thatcorrespond to IOMMU contexts assigned through Host1x to processes.Even when host1x itself is built as a module, the bus is registeredin built-in code so that the built-in ARM SMMU driver is able toreference it.Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/gpu/host1x/Kconfig

c8a20364 - gpu: host1x: Unconditionally select IOMMU_IOVA

Thu, 29 Aug 2019 15:56:53 +0000

gpu: host1x: Unconditionally select IOMMU_IOVACurrently configurations can be generated where IOMMU_SUPPORT isdisabled but IOMMU_IOVA is built as a module and HOST1X as built-in. Insuch a case, the symbols guarded by IOMMU_IOVA will not be availablewhen linking the host1x driver and cause a linking failure.Simplify this by unconditionally selecting IOMMU_IOVA, which makes surethat it will be forced to =y if HOST1X=y. Technically we can now getIOMMU_IOVA code built-in even if we don't use it (host1x only uses itwhen IOMMU_SUPPORT is also enabled), but such configuration are of amostly academic nature. In all practical configurations we want IOMMUsupport anyway.Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/gpu/host1x/Kconfig

6f44c2b5 - gpu: host1x: Increase compile test coverage

Wed, 20 Nov 2013 19:58:36 +0000

gpu: host1x: Increase compile test coverageThe ARCH_MULTIPLATFORM dependency was introduced back when Tegra didn'tsupport multiplatform yet as a means to allow the driver to be easilycompile-tested along with other DRM drivers. In the meantime, the newCOMPILE_TEST Kconfig option has been introduced for exactly thatpurpose, so use that instead to clarify the intention.Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/gpu/host1x/Kconfig
