background: not each pixel requires update in post processing, it happends: - on left boundary blocks since dst horizontal offset must be dword alignment - on right boundary blocks when offset_x+width is not 16 aligned - on botton boundary blocks when offset_y+height is not 8 aligned - (we needn't take special care to top boundary blocks, since dst vertical offset only requires byte alignment) https://bugs.freedesktop.org/show_bug.cgi?id=51553
solution: we introduce left/right/bottom mask to mask out the pixels which are not interested. - dst horizontal offset is shifted left to meet dword alignment - src horizontal offset requires recalcultion - src and dst width requires recalculation - src_normalized_x and normalized_video_x_scaling_step requires recalculation - block horizontal mask is initialized + to left mask (1*N or left edge of M*1) + to right mask (right edge of M*1) + to 0xffff, in else case - block horitontal mask is updated to middle mask after the very first block, and update to right mask for the very last block. - 'middle mask': + middle mask can be equal to left mask for left strip (in M*1 block partition), + middle mask can be equal to right mask for the right strip (in M*1 block partition) + middle mask is equal to 0xffff in 1*N block partition mode + right edge condition is checked after middle block condition in case there are just 2 blocks in the dst region - right mask has the similar trick as middle mask - block vertical mask is initialized to 0xff except it is a bottom strip (in 1*N block partition mode), - block vertical mask is updated to 'bottom' mask for the very last block. + it is a real bottom mask in 1*N block partition, or bottom strip in M*1 block partition. + it is 0xff in else condition (M*1 block partition, not bottom strip) besides nv12 avs update, I also update load/save and nv12 scaling since I used them during debug Zhao Halley (8): enable horizontal and vertical mask for bottom/right boundary blocks reload block mask for the last(bottom/right) block in a strip PL8x4_Save_IMC3.asm fix of masked block work around hw limitation(dword alignment) of horizontal offset reload horizontal mask after the first block in asm code use load/save procedure instead of scaling only when work around hw limitation(dword alignment) of horizontal offset work around hw limitation(dword alignment) of horizontal offset src/i965_post_processing.c | 136 ++++++++++++++++---- src/i965_post_processing.h | 22 +++- .../gen5_6/Common/Multiple_Loop.asm | 11 +- .../gen5_6/Common/PL8x4_Save_IMC3.asm | 2 +- .../post_processing/gen5_6/Common/common.inc | 7 + .../post_processing/gen5_6/nv12_avs_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_avs_nv12.g6b | 10 +- .../post_processing/gen5_6/nv12_dn_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_dn_nv12.g6b | 10 +- .../post_processing/gen5_6/nv12_dndi_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_dndi_nv12.g6b | 10 +- .../gen5_6/nv12_load_save_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_load_save_nv12.g6b | 10 +- .../gen5_6/nv12_load_save_pa.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_load_save_pa.g6b | 10 +- .../gen5_6/nv12_load_save_pl3.g4b.gen5 | 18 ++- .../post_processing/gen5_6/nv12_load_save_pl3.g6b | 18 ++- .../gen5_6/nv12_load_save_rgbx.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_load_save_rgbx.g6b | 10 +- .../gen5_6/nv12_scaling_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/nv12_scaling_nv12.g6b | 10 +- .../gen5_6/pa_load_save_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/pa_load_save_nv12.g6b | 10 +- .../gen5_6/pa_load_save_pl3.g4b.gen5 | 18 ++- .../post_processing/gen5_6/pa_load_save_pl3.g6b | 18 ++- .../gen5_6/pl3_load_save_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/pl3_load_save_nv12.g6b | 10 +- .../gen5_6/pl3_load_save_pa.g4b.gen5 | 10 +- .../post_processing/gen5_6/pl3_load_save_pa.g6b | 10 +- .../gen5_6/pl3_load_save_pl3.g4b.gen5 | 18 ++- .../post_processing/gen5_6/pl3_load_save_pl3.g6b | 18 ++- .../gen5_6/rgbx_load_save_nv12.g4b.gen5 | 10 +- .../post_processing/gen5_6/rgbx_load_save_nv12.g6b | 10 +- 33 files changed, 370 insertions(+), 136 deletions(-) mode change 100644 => 100755 src/shaders/post_processing/gen5_6/Common/Multiple_Loop.asm mode change 100644 => 100755 src/shaders/post_processing/gen5_6/Common/PL8x4_Save_IMC3.asm mode change 100644 => 100755 src/shaders/post_processing/gen5_6/Common/common.inc -- 1.7.9.5 _______________________________________________ Libva mailing list Libva@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libva
