Date: Sun, 22 May 2011 03:12:33 +0200 From: Uwaysi Bin Kareem <uwaysi.bin.kareem@...adoxuncreated.com> To: linux-kernel@...r.kernel.org Subject: Re: Linux 2.6.39 2.6.39 first observations: The framerate jitter in games that seem to depend on kernel for low-jitter, like doom 3, is almost completely gone now. (Tested with latest nvidia driver something 75 something) I decided to try threadirqs from grub, but that did not work. Looks like the same error as I get when I tried the rt kernels, which was this one: http://www.paradoxuncreated.com/tmp/rterror.jpg Peace Be With You, Uwaysi. http://www.paradoxuncreated.com/tmp/.config39 Pentium(R) Dual-Core CPU E5200 @ 2.50GHz uwaysi@...lennium:~$ lspci -v 00:00.0 Host bridge: nVidia Corporation C55 Host Bridge (rev a2) Flags: bus master, 66MHz, fast devsel, latency 0 Capabilities: <access denied> 00:00.1 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:00.2 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:00.3 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: bus master, 66MHz, fast devsel, latency 0 00:00.4 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: bus master, 66MHz, fast devsel, latency 0 00:00.5 RAM memory: nVidia Corporation C55 Memory Controller (rev a2) Flags: bus master, 66MHz, fast devsel, latency 0 00:00.6 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:00.7 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.0 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.1 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.2 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.3 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.4 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.5 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:01.6 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:02.0 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:02.1 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: bus master, 66MHz, fast devsel, latency 0 00:02.2 RAM memory: nVidia Corporation C55 Memory Controller (rev a1) Flags: 66MHz, fast devsel 00:03.0 PCI bridge: nVidia Corporation C55 PCI Express bridge (rev a1) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=01, subordinate=05, sec-latency=0 I/O behind bridge: 0000d000-0000dfff Memory behind bridge: fa000000-feafffff Prefetchable memory behind bridge: 00000000d0000000-00000000dfffffff Capabilities: <access denied> Kernel driver in use: pcieport Kernel modules: shpchp 00:06.0 PCI bridge: nVidia Corporation C55 PCI Express bridge (rev a1) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=06, subordinate=06, sec-latency=0 Capabilities: <access denied> Kernel driver in use: pcieport Kernel modules: shpchp 00:07.0 PCI bridge: nVidia Corporation C55 PCI Express bridge (rev a1) (prog-if 00 [Normal decode]) Flags: bus master, fast devsel, latency 0 Bus: primary=00, secondary=07, subordinate=07, sec-latency=0 Capabilities: <access denied> Kernel driver in use: pcieport Kernel modules: shpchp 00:09.0 RAM memory: nVidia Corporation MCP51 Host Bridge (rev a2) Subsystem: Micro-Star International Co., Ltd.
