linux-toradex.git/drivers/gpu/drm/radeon/si_dpm.h, branch v4.9.2 Linux kernel for Apalis and Colibri modules drm/radeon: bind fan control on SI cards to hwmon interface 2015-01-22T15:38:48+00:00 Alex Deucher alexander.deucher@amd.com 2015-01-07T20:29:06+00:00 5e8150a6876a2a7784b0029506c90ab3d26c9a41 This adds a possibility to control fan on SI parts via exported hwmon variables. Note that automatic ucode fan management pauses if you choose to enable manual fan control. Use with caution! Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

drm/radeon/kms: add dpm support for SI (v7) 2013-06-27T23:40:05+00:00 Alex Deucher alexander.deucher@amd.com 2013-06-25T21:56:16+00:00 a9e61410921bcc1aa8f594ffa6301d5baba90f3b This adds dpm support for SI asics. This includes: - dynamic engine clock scaling - dynamic memory clock scaling - dynamic voltage scaling - dynamic pcie gen1/gen2/gen3 switching - power containment - shader power scaling Set radeon.dpm=1 to enable. v2: enable hainan support, rebase v3: guard acpi stuff v4: fix 64 bit math v5: fix 64 bit div harder v6: fix thermal interrupt check noticed by Jerome v7: attempt fix state enable Signed-off-by: Alex Deucher <alexander.deucher@amd.com> 
This adds dpm support for SI asics.  This includes:
- dynamic engine clock scaling
- dynamic memory clock scaling
- dynamic voltage scaling
- dynamic pcie gen1/gen2/gen3 switching
- power containment
- shader power scaling

Set radeon.dpm=1 to enable.

v2: enable hainan support, rebase
v3: guard acpi stuff
v4: fix 64 bit math
v5: fix 64 bit div harder
v6: fix thermal interrupt check noticed by Jerome
v7: attempt fix state enable
