It appears the hw really doesn't like setting these registers while stuff is running, this moves the setting of the registers into the modeset since they aren't required to be changed anywhere else. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=35183 Reported-and-tested-by: Álmos <aaalmosss@gmail.com Signed-off-by: Dave Airlie <airlied@redhat.com> --- drivers/gpu/drm/radeon/r100.c | 17 ----------------- drivers/gpu/drm/radeon/radeon_legacy_crtc.c | 3 ++- 2 files changed, 2 insertions(+), 18 deletions(-) (limited to 'drivers') diff --git a/drivers/gpu/drm/radeon/r100.c b/drivers/gpu/drm/radeon/r100.c index 93fa735c8c1a..79de991e1ea3 100644 --- a/drivers/gpu/drm/radeon/r100.c +++ b/drivers/gpu/drm/radeon/r100.c @@ -70,23 +70,6 @@ MODULE_FIRMWARE(FIRMWARE_R520); void r100_pre_page_flip(struct radeon_device *rdev, int crtc) { - struct radeon_crtc *radeon_crtc = rdev->mode_info.crtcs[crtc]; - u32 tmp; - - /* make sure flip is at vb rather than hb */ - tmp = RREG32(RADEON_CRTC_OFFSET_CNTL + radeon_crtc->crtc_offset); - tmp &= ~RADEON_CRTC_OFFSET_FLIP_CNTL; - /* make sure pending bit is asserted */ - tmp |= RADEON_CRTC_GUI_TRIG_OFFSET_LEFT_EN; - WREG32(RADEON_CRTC_OFFSET_CNTL + radeon_crtc->crtc_offset, tmp); - - /* set pageflip to happen as late as possible in the vblank interval. - * same field for crtc1/2 - */ - tmp = RREG32(RADEON_CRTC_GEN_CNTL); - tmp &= ~RADEON_CRTC_VSTAT_MODE_MASK; - WREG32(RADEON_CRTC_GEN_CNTL, tmp); - /* enable the pflip int */ radeon_irq_kms_pflip_irq_get(rdev, crtc); } diff --git a/drivers/gpu/drm/radeon/radeon_legacy_crtc.c b/drivers/gpu/drm/radeon/radeon_legacy_crtc.c index cf0638c3b7c7..78968b738e88 100644 --- a/drivers/gpu/drm/radeon/radeon_legacy_crtc.c +++ b/drivers/gpu/drm/radeon/radeon_legacy_crtc.c @@ -443,7 +443,7 @@ int radeon_crtc_do_set_base(struct drm_crtc *crtc, (target_fb->bits_per_pixel * 8)); crtc_pitch |= crtc_pitch << 16; - + crtc_offset_cntl |= RADEON_CRTC_GUI_TRIG_OFFSET_LEFT_EN; if (tiling_flags & RADEON_TILING_MACRO) { if (ASIC_IS_R300(rdev)) crtc_offset_cntl |= (R300_CRTC_X_Y_MODE_EN | @@ -502,6 +502,7 @@ int radeon_crtc_do_set_base(struct drm_crtc *crtc, gen_cntl_val = RREG32(gen_cntl_reg); gen_cntl_val &= ~(0xf << 8); gen_cntl_val |= (format << 8); + gen_cntl_val &= ~RADEON_CRTC_VSTAT_MODE_MASK; WREG32(gen_cntl_reg, gen_cntl_val); crtc_offset = (u32)base; -- cgit v1.2.3
