From: Joseph Gravenor <[email protected]> [why] dp_48m_refclk_driver_pwdn is persistent through S3 and S5. This was worked arround in SMU FW 55.21.0. Earlier FW don't have this fix so we will hang on reboot
[how] add a guard for smu versions before SMU FW 55.21.0 Change-Id: I26b1a7f90218b4fd016ef242f09faa5900cbec55 Signed-off-by: Joseph Gravenor <[email protected]> --- drivers/gpu/drm/amd/display/dc/clk_mgr/dcn21/rn_clk_mgr.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/gpu/drm/amd/display/dc/clk_mgr/dcn21/rn_clk_mgr.c b/drivers/gpu/drm/amd/display/dc/clk_mgr/dcn21/rn_clk_mgr.c index a2a4c7ddc856..68d38239304c 100644 --- a/drivers/gpu/drm/amd/display/dc/clk_mgr/dcn21/rn_clk_mgr.c +++ b/drivers/gpu/drm/amd/display/dc/clk_mgr/dcn21/rn_clk_mgr.c @@ -649,7 +649,7 @@ void rn_clk_mgr_construct( pp_smu->rn_funcs.set_wm_ranges(&pp_smu->rn_funcs.pp_smu, &ranges); } - if (!IS_FPGA_MAXIMUS_DC(ctx->dce_environment)) { + if (!IS_FPGA_MAXIMUS_DC(ctx->dce_environment) && clk_mgr->smu_ver >= 0x00371500) { /* enable powerfeatures when displaycount goes to 0 */ rn_vbios_smu_enable_48mhz_tmdp_refclk_pwrdwn(clk_mgr, !debug->disable_48mhz_pwrdwn); } -- 2.17.1 _______________________________________________ amd-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/amd-gfx
