gpu: host1x: Add Tegra194 support

2018-11-29T16:11:49+00:00

The host1x hardware found on Tegra194 is mostly backwards compatible with the version found on Tegra186, with the notable exceptions of the increased number of syncpoints and mlocks. In addition, some rarely used features such as syncpoint wait bases were dropped and some registers had to move around to accomodate the increased number of syncpoints. Signed-off-by: Thierry Reding

gpu: host1x: Remove wait check support

2018-05-18T19:50:04+00:00

The job submission userspace ABI doesn't support this and there are no plans to implement it, so all of this code is dead and can be removed. Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Enable Tegra186 syncpoint protection

2017-10-20T12:19:52+00:00

Since Tegra186 the Host1x hardware allows syncpoints to be assigned to specific channels, preventing any other channels from incrementing them. Enable this feature where available and assign syncpoints to channels when submitting a job. Syncpoints are currently never unassigned from channels since that would require extra work and is unnecessary with the current channel allocation model.

gpu: host1x: Fix bitshift/mask multipliers

2017-08-17T15:57:06+00:00

Some parts of Host1x uses BIT_WORD/BIT_MASK/BITS_PER_LONG to calculate register or field offsets. This worked fine on ARMv7, but now that BITS_PER_LONG is 64 but our registers are still 32-bit things are broken. Fix by replacing.. - BIT_WORD with (x / 32) - BIT_MASK with BIT(x % 32) - BITS_PER_LONG with 32 Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Whitespace cleanup for readability

2016-06-23T09:59:30+00:00

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

2016-06-23T09:59:28+00:00

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: Consistently use unsigned int for counts

2016-06-23T09:59:23+00:00

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: Use relative include paths

2013-10-31T08:55:40+00:00

This is slightly safer than adding -Idrivers/gpu/host1x to cflags-y. Signed-off-by: Thierry Reding

gpu: host1x: Rework CPU syncpoint increment

2013-06-22T10:43:55+00:00

This patch merges host1x_syncpt_cpu_incr to host1x_syncpt_incr() as they are in practise doing the same thing. host1x_syncpt_incr() is also modified to return error codes. User space interface is modified accordingly to pass return values. Signed-off-by: Arto Merilainen Acked-By: Terje Bergstrom Signed-off-by: Thierry Reding
