To: intel-gfx
For Gen11+ platforms BSpec suggests disabling specific
QGV points separately, depending on bandwidth limitations
and current display configuration. Thus it required adding
a new PCode request for disabling QGV points and some
refactoring of already existing SAGV code.
Also had to refactor intel_can_enable_sagv function,
as current seems to be outdated and using skl specific
workarounds, also not following BSpec for Gen11+.
v25: Rebased patch series as part was merged already
v26: Had to resend the whole series as one more mid patch was added
v27: Patches 2,3,7 were pushed, have to resend the series to prevent
build failure.
v28: PCode patch was merged, one patch was added, sent new series.
Stanislav Lisovskiy (6):
drm/i915: Introduce skl_plane_wm_level accessor.
drm/i915: Extract skl SAGV checking
drm/i915: Make active_pipes check skl specific
drm/i915: Add TGL+ SAGV support
drm/i915: Restrict qgv points which don't have enough bandwidth.
drm/i915: Enable SAGV support for Gen12

So this accessor will give additional flexibility to do that. Currently this accessor is still simply working as "pass-through" function. This will be changed in next coming patches from this series. v2: - plane_id -> plane->id(Ville Syrjälä) - Moved wm_level var to have more local scope (Ville Syrjälä) - Renamed yuv to color_plane(Ville Syrjälä) in skl_plane_wm_level v3: - plane->id -> plane_id(this time for real, Ville Syrjälä) - Changed colorplane id type from boolean to int as index (Ville Syrjälä) - Moved crtc_state param so that it is first now (Ville Syrjälä) - Moved wm_level declaration to tigher scope in skl_write_plane_wm(Ville Syrjälä) v4: - Started to use enum values for color plane - Do sizeof for a type what we are memset'ing - Zero out wm_uv as well(Ville Syrjälä) v5: - Fixed rebase conflict caused by COLOR_PLANE_* enum removal v6: - Do not use skl_plane_wm_level accessor in skl_allocate_pipe_ddb v7: - Get rid of wm_uv, which is not used in skl_plane_write_wm(Ville) Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> --- drivers/gpu/drm/i915/intel_pm.c | 23 +++++++++++++++++++++-- 1 file changed, 21 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_pm.c b/drivers/gpu/drm/i915/intel_pm.c index 416cb1a1e7cb..9be2d1bea4c3 100644 --- a/drivers/gpu/drm/i915/intel_pm.c +++ b/drivers/gpu/drm/i915/intel_pm.c @@ -4632,6 +4632,17 @@ icl_get_total_relative_data_rate(struct intel_crtc_state *crtc_state, return total_data_rate; } +static const struct skl_wm_level * +skl_plane_wm_level(const struct intel_crtc_state *crtc_state, + enum plane_id plane_id, + int level) +{ + const struct skl_plane_wm *wm = + &crtc_state->wm.skl.optimal.planes[plane_id]; + + return &wm->wm[level]; +} + static int skl_allocate_pipe_ddb(struct intel_crtc_state *crtc_state) { @@ -5439,8 +5450,12 @@ void skl_write_plane_wm(struct intel_plane *plane, &crtc_state->wm.skl.plane_ddb_uv[plane_id]; for (level = 0; level <= max_level; level++) { + const struct skl_wm_level *wm_level; + + wm_level = skl_plane_wm_level(crtc_state, plane_id, level); + skl_write_wm_level(dev_priv, PLANE_WM(pipe, plane_id, level), - &wm->wm[level]); + wm_level); } skl_write_wm_level(dev_priv, PLANE_WM_TRANS(pipe, plane_id), &wm->trans_wm); @@ -5473,8 +5488,12 @@ void skl_write_cursor_wm(struct intel_plane *plane, &crtc_state->wm.skl.plane_ddb_y[plane_id]; for (level = 0; level <= max_level; level++) { + const struct skl_wm_level *wm_level; + + wm_level = skl_plane_wm_level(crtc_state, plane_id, level); + skl_write_wm_level(dev_priv, CUR_WM(pipe, level), - &wm->wm[level]); + wm_level); } skl_write_wm_level(dev_priv, CUR_WM_TRANS(pipe), &wm->trans_wm); -- 2.24.1.485.gad05a3d8e5 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply related [flat|nested] 13+ messages in thread

Currently we are just comparing against all of those and take minimum(worst case). v2: Fixed wrong PCode reply mask, removed hardcoded values. v3: Forbid simultaneous legacy SAGV PCode requests and restricting qgv points. Put the actual restriction to commit function, added serialization(thanks to Ville) to prevent commit being applied out of order in case of nonblocking and/or nomodeset commits. v4: - Minor code refactoring, fixed few typos(thanks to James Ausmus) - Change the naming of qgv point masking/unmasking functions(James Ausmus). - Simplify the masking/unmasking operation itself, as we don't need to mask only single point per request(James Ausmus) - Reject and stick to highest bandwidth point if SAGV can't be enabled(BSpec) v5: - Add new mailbox reply codes, which seems to happen during boot time for TGL and indicate that QGV setting is not yet available. v6: - Increase number of supported QGV points to be in sync with BSpec. v7: - Rebased and resolved conflict to fix build failure. - Fix NUM_QGV_POINTS to 8 and moved that to header file(James Ausmus) v8: - Don't report an error if we can't restrict qgv points, as SAGV can be disabled by BIOS, which is completely legal. So don't make CI panic. Instead if we detect that there is only 1 QGV point accessible just analyze if we can fit the required bandwidth requirements, but no need in restricting. v9: - Fix wrong QGV transition if we have 0 planes and no SAGV simultaneously. v10: - Fix CDCLK corruption, because of global state getting serialized without modeset, which caused copying of non-calculated cdclk to be copied to dev_priv(thanks to Ville for the hint). v11: - Remove unneeded headers and spaces(Matthew Roper) - Remove unneeded intel_qgv_info qi struct from bw check and zero out the needed one(Matthew Roper) - Changed QGV error message to have more clear meaning(Matthew Roper) - Use state->modeset_set instead of any_ms(Matthew Roper) - Moved NUM_SAGV_POINTS from i915_reg.h to i915_drv.h where it's used - Keep using crtc_state->hw.active instead of .enable(Matthew Roper) - Moved unrelated changes to other patch(using latency as parameter for plane wm calculation, moved to SAGV refactoring patch) v12: - Fix rebase conflict with own temporary SAGV/QGV fix. - Remove unnecessary mask being zero check when unmasking qgv points as this is completely legal(Matt Roper) - Check if we are setting the same mask as already being set in hardware to prevent error from PCode. - Fix error message when restricting/unrestricting qgv points to "mask/unmask" which sounds more accurate(Matt Roper) - Move sagv status setting to icl_get_bw_info from atomic check as this should be calculated only once.(Matt Roper) - Edited comments for the case when we can't enable SAGV and use only 1 QGV point with highest bandwidth to be more understandable.(Matt Roper) v13: - Moved max_data_rate in bw check to closer scope(Ville Syrjälä) - Changed comment for zero new_mask in qgv points masking function to better reflect reality(Ville Syrjälä) - Simplified bit mask operation in qgv points masking function (Ville Syrjälä) - Moved intel_qgv_points_mask closer to gen11 SAGV disabling, however this still can't be under modeset condition(Ville Syrjälä) - Packed qgv_points_mask as u8 and moved closer to pipe_sagv_mask (Ville Syrjälä) - Extracted PCode changes to separate patch.(Ville Syrjälä) - Now treat num_planes 0 same as 1 to avoid confusion and returning max_bw as 0, which would prevent choosing QGV point having max bandwidth in case if SAGV is not allowed, as per BSpec(Ville Syrjälä) - Do the actual qgv_points_mask swap in the same place as all other global state parts like cdclk are swapped. In the next patch, this all will be moved to bw state as global state, once new global state patch series from Ville lands v14: - Now using global state to serialize access to qgv points - Added global state locking back, otherwise we seem to read bw state in a wrong way. v15: - Added TODO comment for near atomic global state locking in bw code. v16: - Fixed intel_atomic_bw_* functions to be intel_bw_* as discussed with Jani Nikula. - Take bw_state_changed flag into use. v17: - Moved qgv point related manipulations next to SAGV code, as those are semantically related(Ville Syrjälä) - Renamed those into intel_sagv_(pre)|(post)_plane_update (Ville Syrjälä) v18: - Move sagv related calls from commit tail into intel_sagv_(pre)|(post)_plane_update(Ville Syrjälä) v19: - Use intel_atomic_get_bw_(old)|(new)_state which is intended for commit tail stage. v20: - Return max bandwidth for 0 planes(Ville) - Constify old_bw_state in bw_atomic_check(Ville) - Removed some debugs(Ville) - Added data rate to debug print when no QGV points(Ville) - Removed some comments(Ville) v21, v22, v23: - Fixed rebase conflict v24: - Changed PCode mask to use ICL_ prefix v25: - Resolved rebase conflict v26: - Removed redundant NULL checks(Ville) - Removed redundant error prints(Ville) Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Cc: Ville Syrjälä <ville.syrjala@intel.com> Cc: James Ausmus <james.ausmus@intel.com> --- drivers/gpu/drm/i915/display/intel_bw.c | 137 +++++++++++++----- drivers/gpu/drm/i915/display/intel_bw.h | 9 ++ .../drm/i915/display/intel_display_types.h | 3 + drivers/gpu/drm/i915/intel_pm.c | 54 ++++++- drivers/gpu/drm/i915/intel_pm.h | 2 + 5 files changed, 167 insertions(+), 38 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_bw.c b/drivers/gpu/drm/i915/display/intel_bw.c index 6e7cc3a4f1aa..d28ca4d0b1c4 100644 --- a/drivers/gpu/drm/i915/display/intel_bw.c +++ b/drivers/gpu/drm/i915/display/intel_bw.c @@ -8,6 +8,9 @@ #include "intel_bw.h" #include "intel_display_types.h" #include "intel_sideband.h" +#include "intel_atomic.h" +#include "intel_pm.h" + /* Parameters for Qclk Geyserville (QGV) */ struct intel_qgv_point { @@ -113,6 +116,26 @@ static int icl_pcode_read_qgv_point_info(struct drm_i915_private *dev_priv, return 0; } +int icl_pcode_restrict_qgv_points(struct drm_i915_private *dev_priv, + u32 points_mask) +{ + int ret; + + /* bspec says to keep retrying for at least 1 ms */ + ret = skl_pcode_request(dev_priv, ICL_PCODE_SAGV_DE_MEM_SS_CONFIG, + points_mask, + ICL_PCODE_POINTS_RESTRICTED_MASK, + ICL_PCODE_POINTS_RESTRICTED, + 1); + + if (ret < 0) { + DRM_ERROR("Failed to disable qgv points (%d)\n", ret); + return ret; + } + + return 0; +} + static int icl_get_qgv_points(struct drm_i915_private *dev_priv, struct intel_qgv_info *qi) { @@ -240,6 +263,16 @@ static int icl_get_bw_info(struct drm_i915_private *dev_priv, const struct intel break; } + /* + * In case if SAGV is disabled in BIOS, we always get 1 + * SAGV point, but we can't send PCode commands to restrict it + * as it will fail and pointless anyway. + */ + if (qi.num_points == 1) + dev_priv->sagv_status = I915_SAGV_NOT_CONTROLLED; + else + dev_priv->sagv_status = I915_SAGV_ENABLED; + return 0; } @@ -248,6 +281,11 @@ static unsigned int icl_max_bw(struct drm_i915_private *dev_priv, { int i; + /* + * Let's return max bw for 0 planes + */ + num_planes = max(1, num_planes); + for (i = 0; i < ARRAY_SIZE(dev_priv->max_bw); i++) { const struct intel_bw_info *bi = &dev_priv->max_bw[i]; @@ -277,34 +315,6 @@ void intel_bw_init_hw(struct drm_i915_private *dev_priv) icl_get_bw_info(dev_priv, &icl_sa_info); } -static unsigned int intel_max_data_rate(struct drm_i915_private *dev_priv, - int num_planes) -{ - if (INTEL_GEN(dev_priv) >= 11) { - /* - * Any bw group has same amount of QGV points - */ - const struct intel_bw_info *bi = - &dev_priv->max_bw[0]; - unsigned int min_bw = UINT_MAX; - int i; - - /* - * FIXME with SAGV disabled maybe we can assume - * point 1 will always be used?
