2014-02-18drm/radeon/ni: fix typo in dpm sq ramping setupAlex Deucher1-1/+1
inverted logic. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2014-02-06drm/radeon/dpm: use stored max_vddc rather than looking it upAlex Deucher1-3/+2
When we parse the power tables use the stored mac_vddc value rather than lookig it up manually each time. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2014-02-06drm/radeon/dpm: use the driver state for dpm debugfsAlex Deucher1-1/+2
For btc and newer, we may modify the power state depending on the circumstances. Use the modified state rather than the base state. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/pm: move pm handling into the asic specific codeAlex Deucher1-0/+6
We need more control over the ordering of dpm init with respect to the rest of the asic. Specifically, the SMC has to be initialized before the rlc and cg/pg. The pm code currently initializes late in the driver, but we need it to happen much earlier so move pm handling into the asic specific callbacks. This makes dpm more reliable and makes clockgating work properly on CIK parts and should help on SI parts as well. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-24drm/radeon/dpm: switch on new late_enable callbackAlex Deucher1-15/+0
Right now it's called right after enable, but after reworking the dpm init order, it will get called later to accomodate loading the smc early, but enabling thermal interrupts and block powergating later after the ring tests are complete. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-12-02drm/radeon/dpm: simplify state adjust logic for NIAlex Deucher1-17/+11
This is based on a similar patch from Alexandre Demers. While fixing up some warnings with that patch I saw some additional cleanups that could be applied. This patch simplifies the logic for patching the power state. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Alexandre Demers <alexandre.f.demers@gmail.com>
2013-11-15drm: radeon: ni_dpm: Fix unused variable warning when CONFIG_ACPI=nFabio Estevam1-1/+1
With CONFIG_ACPI=n the following build warning is seen: drivers/gpu/drm/radeon/ni_dpm.c:3448:31: warning: unused variable 'eg_pi' [-Wunused-variable] Move the definition of eg_pi inside the CONFIG_ACPI 'if' block.

2013-09-23drm/radeon/dpm/ni: filter clocks based on voltage/clk dep tablesAlex Deucher1-0/+24
filter out mclk and sclk levels higher than listed in the clk voltage dependency tables. Supporting these clocks will require additional driver tweaking that isn't supported yet. See bug: https://bugs.freedesktop.org/show_bug.cgi?id=68235 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-09-15drm/radeon/dpm: rework auto performance level enableAlex Deucher1-6/+0
Calling force_performance_level() from set_power_state() doesn't work on some asics because the current power state pointer has not been properly updated at that point. Move the calls to force_performance_level() out of the asic specific set_power_state() functions and into the main power state sequence. Fixes dpm resume on SI. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: make sure dc performance level limits are valid (BTC-SI) (v2)Alex Deucher1-0/+6
Check to make sure the dc limits are valid before using them. Some systems may not have a dc limits table. In that case just use the ac limits. This fixes hangs on systems when the power state is changed when on battery (dc) due to invalid performance state parameters. Should fix: https://bugs.freedesktop.org/show_bug.cgi?id=68708 v2: fix up limits in dpm_init() Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
2013-08-30drm/radeon: gcc fixes for ni dpmAlex Deucher1-2/+3
Newer versions of gcc seem to wander off into the weeds when dealing with variable sizes arrays in structs. Rather than indexing the arrays, use pointer arithmetic. See bugs: https://bugs.freedesktop.org/show_bug.cgi?id=66932 https://bugs.freedesktop.org/show_bug.cgi?id=66972 https://bugs.freedesktop.org/show_bug.cgi?id=66945 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-30drm/radeon/dpm: adjust the vblank time checks for eg, ni, siAlex Deucher1-1/+2
According to the internal teams, we never hit the limit for mclk switching on these asics, so we can disable the check. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon/dpm: fix spread spectrum setup (v2)Alex Deucher1-13/+1
Need to check for engine and memory clock ss separately and only enable dynamic ss if either of them are found. This should fix systems which have a ss table, but do not have entries for engine or memory. On those systems we may enable dynamic spread spectrum without enabling it on the engine or memory clocks which can lead to a hang in some cases. fixes some systems reported here: https://bugs.freedesktop.org/show_bug.cgi?id=66963 v2: fix typo Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2013-08-07drm/radeon/dpm: adjust thermal protection requirementsAlex Deucher1-2/+1
On rv770 and newer, clock gating is not required for thermal protection. The only requirement is that the design utilizes a thermal sensor. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2013-07-08drm/radeon/dpm: implement vblank_too_short callback for caymanAlex Deucher1-1/+15
