It's a good practice to release resource in one place and help eliminate some duplicated code. Signed-off-by: Miaohe Lin <linmiaohe@huawei.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

H A D | atomic_lse.h | diff 2efe95fe Fri Apr 22 11:01:33 MDT 2016 Will Deacon <will@kernel.org> locking/atomic, arch/arm64: Implement atomic{,64}_fetch_{add,sub,and,andnot,or,xor}{,_relaxed,_acquire,_release}() for LSE instructions Implement FETCH-OP atomic primitives, these are very similar to the existing OP-RETURN primitives we already have, except they return the value of the atomic variable _before_ modification. This is especially useful for irreversible operations -- such as bitops (because it becomes impossible to reconstruct the state prior to modification). This patch implements the LSE variants.

Only after IMA was initialized in late_initcall were the counters updated. This patch updates the counters, whether or not IMA has been initialized, to resolve 'imbalance' messages. This patch fixes the bug as reported in bugzilla: 15673. When the i915 is builtin, the ring_buffer is initialized before IMA, causing the imbalance message on suspend.

But for all other DDI ports it can drive HDMI or DP depending on what user connects to the ports. ehl_get_combo_buf_trans() and tgl_get_combo_buf_trans() was checking for INTEL_OUTPUT_DP that was never true, causing wrong vswing tables being used. So here replacing the INTEL_OUTPUT_DP checks by the valid output types that this functions receives as parameters. HDMI cases will be correctly handled as it do not use encoder->type, instead it calls the functions with INTEL_OUTPUT_HDMI as type parameter and HDMI don't have retraining. v2: changed INTEL_OUTPUT_DDI to INTEL_OUTPUT_EDP and INTEL_OUTPUT_HDMI Fixes: bd3cf6f7ce20 ("drm/i915/dp/tgl+: Update combo phy vswing tables") Cc: Clinton A Taylor <clinton.a.taylor@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200330210044.130510-1-jose.souza@intel.com (cherry picked from commit 70988115ac69ecc249aa0f8e8265e8daf87bc28c) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> |
