2021-02-09drm/amd/display: fix type mismatch error for return variableDale Zhao1-1/+1
It is possible for ret_vsnprintf to be assigned negative value in error cases. As an unsigned variable, negative values which are stored in their 2's complement form gets treated as a positive number. This will led to treating bad cases as good ones. eg: -1 gets stored as 0xFFFFFFFF on a 32 bit system Signed-off-by: Dale Zhao <dale.zhao@amd.com> Reviewed-by: Yongqiang Sun <yongqiang.sun@amd.com> Acked-by: Anson Jacob <Anson.Jacob@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-07-18drm/amd/display: refactor dump_clk_registersSu Sung Chung1-1/+1
[why] for 2 purposes: 1. get raw register value dumped on the log, which will make it easier to talk to other team who only knows about the register 2. enable other HW to be able to use the same interface as raven to log clock register data Signed-off-by: Su Sung Chung <Su.Chung@amd.com> Reviewed-by: Tony Cheng <Tony.Cheng@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-05-31drm/amd/display: make clk mgr soc specificEric Yang1-1/+1
[Why] First step of refactoring clk mgr to better handle different ways of handling clock operations. Clock operation policies are soc specific and not just DCN vesion specific. It is not a hw resource, should not be in the resource pool. [How] Change clock manager creation to be based on HW internal ID, rename clock manager members to be more clear. Move clock manager out of resource.

2019-04-03drm/amd/display: Fix multi-thread writing to 1 stateAidan Wood1-6/+6
[Why] Multiple threads were writing back to one global VBA in DC resulting in multiple threads overwriting eachother's data [How] Add an instance of DML (which contains VBA) to each context and change all calls that used dc->dml to use context->dml. Created a seperate copy constructor for linux in a case where there is no access to DC.

2019-03-19drm/amd/display: fix up reference clock abstractionsJun Lei1-2/+2
[why] "reference clock" is a very overloaded variable in DC and causes confusion as there are multiple sources of reference clock, which may be different values incorrect input values to DML will cause DCHUB to be programmed improperly and lead to hard to debug underflow issues [how] instead of using ref clock everywhere, specify WHICH ref clock: - xtalin - dccg refclk - dchub refclk these are all distinct values which may not be equal Signed-off-by: Jun Lei <Jun.Lei@amd.com> Reviewed-by: Yongqiang Sun <yongqiang.sun@amd.com> Acked-by: David Francis <David.Francis@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-01-14drm/amd/display: fix compliler errors [-Werror,-Wmissing-braces]Shirish S1-1/+2
Initializing structures with { } is known to be problematic since it doesn't necessararily initialize all bytes, in case of padding, causing random failures when structures are memcmp(). This patch fixes the structure initialisation related compiler error by memset.
