gpu: host1x: Refactor channel allocation code

2017-06-15T12:25:38Z

This is largely a rewrite of the Host1x channel allocation code, bringing several changes: - The previous code could deadlock due to an interaction between the 'reflock' mutex and CDMA timeout handling. This gets rid of the mutex. - Support for more than 32 channels, required for Tegra186 - General refactoring, including better encapsulation of channel ownership handling into channel.c Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: channel: Use correct type

find_first_zero_bit() returns an unsigned long, so make the local variable that stores the result the same type 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
