linux-toradex.git/drivers/gpu/host1x/channel.h, branch v4.19-rc1 Linux kernel for Apalis and Colibri modules gpu: host1x: Refactor channel allocation code 2017-06-15T12:25:38+00:00 Mikko Perttunen mperttunen@nvidia.com 2017-06-14T23:18:42+00:00 8474b02531c4881a762c52ef869c52429e38633f 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 <mperttunen@nvidia.com> Reviewed-by: Dmitry Osipenko <digetx@gmail.com> Tested-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
