From 6e909f74db2aa9c5b5606b81efcbe18f2749b008 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 7 Aug 2014 09:28:31 -0400 Subject: drm/radeon: add bapm module parameter Add a module paramter to enable bapm on APUs. It's disabled by default on certain APUs due to stability issues. This option makes it easier to test and to enable it on systems that are stable. bug: https://bugzilla.kernel.org/show_bug.cgi?id=81021 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org --- drivers/gpu/drm/radeon/kv_dpm.c | 5 ++++- drivers/gpu/drm/radeon/radeon.h | 1 + drivers/gpu/drm/radeon/radeon_drv.c | 4 ++++ drivers/gpu/drm/radeon/trinity_dpm.c | 24 +++++++++++++++--------- 4 files changed, 24 insertions(+), 10 deletions(-) (limited to 'drivers/gpu/drm/radeon') diff --git a/drivers/gpu/drm/radeon/kv_dpm.c b/drivers/gpu/drm/radeon/kv_dpm.c index 9ef8c38f2d6..c667d83bfa2 100644 --- a/drivers/gpu/drm/radeon/kv_dpm.c +++ b/drivers/gpu/drm/radeon/kv_dpm.c @@ -2726,7 +2726,10 @@ int kv_dpm_init(struct radeon_device *rdev) pi->caps_sclk_ds = true; pi->enable_auto_thermal_throttling = true; pi->disable_nb_ps3_in_battery = false; - pi->bapm_enable = true; + if (radeon_bapm == 0) + pi->bapm_enable = false; + else + pi->bapm_enable = true; pi->voltage_drop_t = 0; pi->caps_sclk_throttle_low_notification = false; pi->caps_fps = false; /* true? */ diff --git a/drivers/gpu/drm/radeon/radeon.h b/drivers/gpu/drm/radeon/radeon.h index 9e1732eb402..e715e0c1f5d 100644 --- a/drivers/gpu/drm/radeon/radeon.h +++ b/drivers/gpu/drm/radeon/radeon.h @@ -105,6 +105,7 @@ extern int radeon_vm_size; extern int radeon_vm_block_size; extern int radeon_deep_color; extern int radeon_use_pflipirq; +extern int radeon_bapm; /* * Copy from radeon_drv.h so we don't have to include both and have conflicting diff --git a/drivers/gpu/drm/radeon/radeon_drv.c b/drivers/gpu/drm/radeon/radeon_drv.c index 092d067f93e..8df88890883 100644 --- a/drivers/gpu/drm/radeon/radeon_drv.c +++ b/drivers/gpu/drm/radeon/radeon_drv.c @@ -180,6 +180,7 @@ int radeon_vm_size = 8; int radeon_vm_block_size = -1; int radeon_deep_color = 0; int radeon_use_pflipirq = 2; +int radeon_bapm = -1; MODULE_PARM_DESC(no_wb, "Disable AGP writeback for scratch registers"); module_param_named(no_wb, radeon_no_wb, int, 0444); @@ -259,6 +260,9 @@ module_param_named(deep_color, radeon_deep_color, int, 0444); MODULE_PARM_DESC(use_pflipirq, "Pflip irqs for pageflip completion (0 = disable, 1 = as fallback, 2 = exclusive (default))"); module_param_named(use_pflipirq, radeon_use_pflipirq, int, 0444); +MODULE_PARM_DESC(bapm, "BAPM support (1 = enable, 0 = disable, -1 = auto)"); +module_param_named(bapm, radeon_bapm, int, 0444); + static struct pci_device_id pciidlist[] = { radeon_PCI_IDS }; diff --git a/drivers/gpu/drm/radeon/trinity_dpm.c b/drivers/gpu/drm/radeon/trinity_dpm.c index 32e50be9c4a..57f780053b3 100644 --- a/drivers/gpu/drm/radeon/trinity_dpm.c +++ b/drivers/gpu/drm/radeon/trinity_dpm.c @@ -1874,16 +1874,22 @@ int trinity_dpm_init(struct radeon_device *rdev) for (i = 0; i < SUMO_MAX_HARDWARE_POWERLEVELS; i++) pi->at[i] = TRINITY_AT_DFLT; - /* There are stability issues reported on with - * bapm enabled when switching between AC and battery - * power.
