gpu: host1x: Add Tegra186 support

2017-10-20T12:19:51Z

Add support for the implementation of Host1x present on the Tegra186. The register space has been shuffled around a little bit, requiring addition of some chip-specific code sections. Tegra186 also adds several new features, most importantly the hypervisor, but those are not yet supported with this commit.

gpu: host1x: Add IOMMU support

2017-04-05T16:11:43Z

Add support for the Host1x unit to be located behind an IOMMU. This is required when gather buffers may be allocated non-contiguously in physical memory, as can be the case when TegraDRM is also using the IOMMU. Signed-off-by: Mikko Perttunen Signed-off-by: Thierry Reding

gpu: host1x: Remove redundant parentheses

2016-06-23T09:59:31Z

There's no need to wrap the BIT() macro into an extra set of parentheses because it's already implemented to use its own set. Signed-off-by: Thierry Reding

gpu: host1x: Whitespace cleanup for readability

2016-06-23T09:59:30Z

Insert a number of blank lines in places where they increase readability of the code. Also collapse various variable declarations to shorten some functions and finally rewrite some code for readability. Signed-off-by: Thierry Reding

gpu: host1x: Use unsigned int consistently for IDs

2016-06-23T09:59:24Z

IDs can never be negative so use unsigned int. In some instances an explicitly sized type (such as u32) was used for no particular reason, so turn those into unsigned int as well for consistency. Signed-off-by: Thierry Reding

gpu: host1x: Consistently use unsigned int for counts

2016-06-23T09:59:23Z

The number of channels, syncpoints, bases and mlocks can never be negative, so use unsigned int instead of int. Also make loop variables the same type for consistency. Signed-off-by: Thierry Reding

gpu: host1x: Print address/offset pairs consistently

2014-11-13T15:11:41Z

Consistently use a format of %pad+%#x to print address/offset in debug messages. Signed-off-by: Thierry Reding

gpu: host1x: Make mapped field of push buffers void *

2014-11-13T15:11:35Z

This reduces the amount of casting that needs to be done to get rid of annoying warnings on 64-bit builds. Signed-off-by: Thierry Reding

gpu: host1x: Silence a few warnings with LPAE=y

2013-11-28T14:13:47Z

When building with LPAE=y (64-bit dma_addr_t), the following warnings are seen: drivers/gpu/host1x/hw/cdma_hw.c:57:3: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t' drivers/gpu/host1x/hw/debug_hw.c:167:10: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'dma_addr_t' The agreed-to solution for this is upcast to u64 and using %llx.
