From: Alex Williamson <alex.williamson@xxxxxxxxxx> [ Upstream commit b75ef35bb57791a5d675699ed4a40c870d1da12f ] Prior to the commit below the GAMT_CHKN_BIT_REG address was setup for devices matching (D_KBL | D_CFL), where intel_gvt_get_device_type() returns D_CFL for either Coffee Lake or Comet Lake. Include the missed platform.` Link: https://lore.kernel.org/all/20220808142711.02d16782.alex.williamson@xxxxxxxxxx Fixes: e0f74ed4634d ("i915/gvt: Separate the MMIO tracking table from GVT-g") Signed-off-by: Alex Williamson <alex.williamson@xxxxxxxxxx> Signed-off-by: Zhenyu Wang <zhenyuw@xxxxxxxxxxxxxxx> Link: http://patchwork.freedesktop.org/patch/msgid/166016852965.780835.10366587502693016900.stgit@omen Reviewed-by: Zhenyu Wang <zhenyuw@xxxxxxxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/gpu/drm/i915/intel_gvt_mmio_table.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/intel_gvt_mmio_table.c b/drivers/gpu/drm/i915/intel_gvt_mmio_table.c index 72dac1718f3e7..6163aeaee9b98 100644 --- a/drivers/gpu/drm/i915/intel_gvt_mmio_table.c +++ b/drivers/gpu/drm/i915/intel_gvt_mmio_table.c @@ -1074,7 +1074,8 @@ static int iterate_skl_plus_mmio(struct intel_gvt_mmio_table_iter *iter) MMIO_D(GEN8_HDC_CHICKEN1); MMIO_D(GEN9_WM_CHICKEN3); - if (IS_KABYLAKE(dev_priv) || IS_COFFEELAKE(dev_priv)) + if (IS_KABYLAKE(dev_priv) || + IS_COFFEELAKE(dev_priv) || IS_COMETLAKE(dev_priv)) MMIO_D(GAMT_CHKN_BIT_REG); if (!IS_BROXTON(dev_priv)) MMIO_D(GEN9_CTX_PREEMPT_REG); -- 2.35.1
