gpu: host1x: Disassemble more instructions

2017-10-20T12:19:52Z

The disassembler for debug dumps was missing some newer host1x opcodes. Add disassembly support for these. Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Improve debug disassembly formatting

2017-10-20T12:19:52Z

The host1x driver prints out "disassembly" dumps of the command FIFO and gather contents on submission timeouts. However, the output has been quite difficult to read with unnecessary newlines and occasional missing parentheses. Fix these problems by using pr_cont to remove unnecessary newlines and by fixing other small issues.

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: 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: Fix a couple of checkpatch warnings

2016-06-23T09:59:28Z

Fix a couple of occurrences where no blank line was used to separate variable declarations from code or where block comments were wrongly formatted. 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: Fix MLOCK's debug info

2015-10-02T12:40:12Z

MLOCK's debug info, spewed on CDMA timeout, contains meaningless MLOCK owner channel ID because HOST1X_SYNC_MLOCK_OWNER_CHID_F() returns shifted value, while unshifted should be used. Fix it by changing '_F' to '_V'. Signed-off-by: Dmitry Osipenko Reviewed-By: Terje Bergstrom 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: 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.
