However, since all dces except -dce80 do not create sw i2c engine, they will still use hw i2c. -This allow enabling/disabling of sw i2c through the feature flag -FEATURE_RESTORE_USAGE_I2C_SW_ENGINE. DCE80 is the only dce that -has sw i2c engine enabled right now due to bug in hw i2c. This -fixes EDID read failure on bonaire. No behaviour change on other -dces. - -Signed-off-by: Eric Yang <eric.yang2@amd.com> -Reviewed-by: Harry Wentland <harry.wentland@amd.com> ---- - drivers/gpu/drm/amd/dal/dc/i2caux/i2caux.c | 9 ++++++++- - 1 file changed, 8 insertions(+), 1 deletion(-) - -diff --git a/drivers/gpu/drm/amd/dal/dc/i2caux/i2caux.c b/drivers/gpu/drm/amd/dal/dc/i2caux/i2caux.c -index 2d394cf..a84901e 100644 ---- a/drivers/gpu/drm/amd/dal/dc/i2caux/i2caux.c -+++ b/drivers/gpu/drm/amd/dal/dc/i2caux/i2caux.c -@@ -122,7 +122,15 @@ bool dal_i2caux_submit_i2c_command( - return false; - } - -+ /* -+ * default will be SW, however there is a feature flag in adapter -+ * service that determines whether SW i2c_engine will be available or -+ * not, if sw i2c is not available we will fallback to hw.
