gpu: host1x: Remove wait check support

2018-05-18T19:50:04Z

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: syncpt: Request syncpoints per client

2017-10-20T12:19:51Z

Rather than request syncpoints for a struct device *, request them for a struct host1x_client *. This is important because subsequent patches are going to break the assumption that host1x will always be the parent for devices requesting a syncpoint. It's also a more natural choice because host1x clients are really the only ones that will know how to deal with syncpoints. Note that host1x clients are always guaranteed to be children of host1x, regardless of their location in the device tree. 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: Add syncpoint base support

2013-10-31T08:55:48Z

This patch adds support for hardware syncpoint bases. This creates a simple mechanism to stall the command FIFO until an operation is completed. Signed-off-by: Arto Merilainen Reviewed-by: Terje Bergstrom Signed-off-by: Thierry Reding

gpu: host1x: Expose syncpt and channel functionality

2013-10-31T08:20:11Z

Expose the buffer objects, syncpoint and channel functionality in the public public header so that drivers can use them. Signed-off-by: Thierry Reding

gpu: host1x: Rework CPU syncpoint increment

2013-06-22T10:43:55Z

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

gpu: host1x: Fix client_managed type

2013-06-22T10:43:54Z

client_managed field in syncpoint structure was defined as an integer. The field holds, however, only a boolean value. This patch modifies the type to boolean. Signed-off-by: Arto Merilainen Acked-By: Terje Bergstrom Signed-off-by: Thierry Reding
