From: Alex Deucher <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit 57700ad1f2f21d5d7ab7ee0e58d11b5954852434 upstream. Setting higher mclks seems to cause stability issues on some R7 260X boards. Disable it for now for stability until we find a proper fix. bug: https://bugs.freedesktop.org/show_bug.cgi?id=75992 Signed-off-by: Alex Deucher <[email protected]> Signed-off-by: Jiri Slaby <[email protected]> --- drivers/gpu/drm/radeon/ci_dpm.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/gpu/drm/radeon/ci_dpm.c b/drivers/gpu/drm/radeon/ci_dpm.c index 51e947a97edf..79682ff51b63 100644 --- a/drivers/gpu/drm/radeon/ci_dpm.c +++ b/drivers/gpu/drm/radeon/ci_dpm.c @@ -5098,6 +5098,10 @@ int ci_dpm_init(struct radeon_device *rdev) pi->mclk_dpm_key_disabled = 0; pi->pcie_dpm_key_disabled = 0; + /* mclk dpm is unstable on some R7 260X cards */ + if (rdev->pdev->device == 0x6658) + pi->mclk_dpm_key_disabled = 1; + pi->caps_sclk_ds = true; pi->mclk_strobe_mode_threshold = 40000; -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
