RZ/G2L SoC embeds Mali-G31 bifrost GPU. This patch series aims to add support for the same It is tested with latest drm-misc-next + mesa 21.3.0 + out of tree patch for (du + DSI) + platform specific mesa configuration for RZ/G2L. Tested the kmscube application. test logs:- root@smarc-rzg2l:~# kmscube Using display 0xaaaadb6e7d30 with EGL version 1.4 =================================== EGL information: version: "1.4" vendor: "Mesa Project" ..... =================================== OpenGL ES 2.x information: version: "OpenGL ES 3.1 Mesa 21.3.0" shading language version: "OpenGL ES GLSL ES 3.10" vendor: "Panfrost" renderer: "Mali-G31 (Panfrost)" .... =================================== ^C root@smarc-rzg2l:~# cat /proc/interrupts | grep panfrost 82: 587287 0 GICv3 186 Level panfrost-job 83: 2 0 GICv3 187 Level panfrost-mmu 84: 8 0 GICv3 185 Level panfrost-gpu root@smarc-rzg2l:~# cat /sys/class/devfreq/11840000.gpu/trans_stat From : To : 50000000 62500000 100000000 125000000 200000000 250000000 400000000 500000000 time(ms) * 50000000: 0 0 0 0 0 0 0 0 72 62500000: 0 0 0 0 0 0 0 0 0 100000000: 0 0 0 0 0 0 0 0 0 125000000: 0 0 0 0 0 0 0 1 68 200000000: 0 0 0 0 0 0 0 1 68 250000000: 1 0 0 0 0 0 0 0 84 400000000: 0 0 0 0 0 0 0 0 0 500000000: 0 0 0 1 1 1 0 0 736 Total transition : 6 root@smarc-rzg2l:~# kmscube Using display 0xaaaaf7a421b0 with EGL version 1.4 =================================== EGL information: version: "1.4" vendor: "Mesa Project" ..... =================================== OpenGL ES 2.x information: version: "OpenGL ES 3.1 Mesa 21.3.0" shading language version: "OpenGL ES GLSL ES 3.10" vendor: "Panfrost" renderer: "Mali-G31 (Panfrost)" ...... =================================== root@smarc-rzg2l:~# root@smarc-rzg2l:~# root@smarc-rzg2l:~# cat /sys/class/devfreq/11840000.gpu/trans_stat From : To : 50000000 62500000 100000000 125000000 200000000 250000000 400000000 500000000 time(ms) * 50000000: 0 0 0 0 0 0 0 1 144 62500000: 0 0 0 0 0 0 0 0 0 100000000: 0 0 0 0 0 0 0 9 524 125000000: 0 0 9 0 0 0 0 3 2544 200000000: 0 0 0 11 0 0 0 46 3304 250000000: 1 0 0 0 33 0 0 0 7496 400000000: 0 0 0 0 16 19 0 0 2024 500000000: 1 0 0 1 8 15 35 0 4032 Total transition : 208 Platform specific mesa configuration patch for RZ/G2L --------------------- src/gallium/targets/dri/meson.build + 'rcar-du_dri.so', src/gallium/targets/dri/target.c +DEFINE_LOADER_DRM_ENTRYPOINT(rcar_du) V2->V3: * Moved optional clock-names and reset-names to SoC-specific conditional schemas. * minimum number of reset for the generic GPU is set to 1. * Documented number of clocks, resets, interrupts and interrupt-names in RZ/G2L SoC-specific conditional schemas. * Updated commit description for patch#3 V1->V2: * Removed clock patches from this seies, as it is accepted for 5.17 * Added Rb tag from Geert * Added reset-names required property for RZ/G2L and updated the board dtsi.
