From b80b13f0cd775669828199ce9b3aee12b9cf8314 Mon Sep 17 00:00:00 2001 From: Tom St Denis Date: Fri, 26 Aug 2016 10:29:19 -0400 Subject: [PATCH] drm/amd/powerplay: Fix CZ SMU firmware load check (v4) Remove an errant return in the middle of the check function as well as check for success in the start function. (v2) Add return check to smu_load_fw() (v3) Don't return early if SMU load check fails (v4) No returns! :-) Signed-off-by: Tom St Denis Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c b/drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c index 87c023e518ab..e6464e21f9b2 100644 --- a/drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c +++ b/drivers/gpu/drm/amd/powerplay/smumgr/cz_smumgr.c @@ -195,9 +195,6 @@ static int cz_check_fw_load_finish(struct pp_smumgr *smumgr, if (smumgr == NULL || smumgr->device == NULL) return -EINVAL; - return cgs_read_register(smumgr->device, - mmSMU_MP1_SRBM2P_ARG_0); - cgs_write_register(smumgr->device, mmMP0PUB_IND_INDEX, index); for (i = 0; i < smumgr->usec_timeout; i++) { @@ -275,7 +272,10 @@ static int cz_start_smu(struct pp_smumgr *smumgr) if (smumgr->chip_id == CHIP_STONEY) fw_to_check &= ~(UCODE_ID_SDMA1_MASK | UCODE_ID_CP_MEC_JT2_MASK); - cz_request_smu_load_fw(smumgr); + ret = cz_request_smu_load_fw(smumgr); + if (ret) + printk(KERN_ERR "[ powerplay] SMU firmware load failed\n"); + cz_check_fw_load_finish(smumgr, fw_to_check); ret = cz_load_mec_firmware(smumgr); -- 2.20.1
