Hi, today, I started with testing "DRM Vblank timestamping patches. 1st Try." from Mario in combination with "radeon pageflipping patches" from Alex together in a non-BKL config Kernel-setup. First some words to my system and hardware: * It's a Debian/sid i386 host with latest dist-upgrades as of today. * My radeon gfxcard is a RV250. [ Linux-kernel ] * Base is a 2.6.36 vanilla Linux-kernel tarball * on top linux-next (next-20101026) with some extra-patches to be able to build a BKL-free Kernel (Thanks Arnd) * on top drm-radeon-testing (up to commit 881fe6c: "drm/radeon/kms: properly compute group_size on 6xx/7xx") * Mario's vblank timestamp caching patches (Rev 1 10.10.2010) with some patches to fit linux-next/drm-radeon-testing * Alex's radeon-KMS pageflipping patches for Kernel * For full patch-series see below NOTE: My Linux-kernel has one speciality: It is BigKerneLock-free ! [ DDX (xf66-video-ati) ] * xf86-video-ati from GIT master (up to commit df92245: "r100: add some missing bits in SE_COORD_FMT") * on top Alex's radeon-KMS pageflipping patch for DDX NOTE from Alex in [2]: "6xx/7xx/evergreen are pretty solid, but r1xx-r5xx still need some work." [ Mesa3D ] * it is from GIT master (up to commit 547e761: "egl_dri2: Fix a typo that make glFlush be called at wrong time.") [ LibDRM ] * 2.4.22-1 from Debian/experimental [ Xorg-server ] * 2:1.9.0.902-1 from Debian/experimental So, how we know Mario made us happy (BTW, greetings from TUE to TUE)? [ dmesg ] [ 8.195646] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010). <--- Driver-date could be changed into more human-readable "10-Oct-2010"? What about the fun Alex gives us? [ /var/log/Xorg.0.log ] [ 1797.204] (II) RADEON(0): KMS Pageflipping: enabled INFO: I have attached the full dmesg and a Xorg.log (with logs after having started Eric Anholt's OpenArena benchmark). Above mentionned OA-benchmark drops fps from ~18 down to 13 (new Kernel + new DDX). I have not tested battery performance. My notebook's LVDS has a 1400x1050 resolution, OA was run @1024x768. Can you enlighten a bit on the other mesages in X log? [ /var/log/Xorg.0.log ] ...

Hope, this feedback is helpful and encourages the diverse involved developers to continue their work. Have fun!
