Date: Mon, 1 Mar 2010 07:11:01 -0600 From: Bob Tracy <rct@...rkin.frus.com> To: linux-kernel@...r.kernel.org Subject: K6-III/450 MTRR support Anyone got a quick way to determine whether MTRR support is working correctly on this old CPU? "cat /proc/mtrr" doesn't show anything configured in cases where I used to see a few entries. Using the "nv" driver (Xorg 1.6.3 dated 2009-07-31: latest version for Slackware 13) produces two error messages... This one appears in syslog: kernel: mtrr: no MTRR for d0000000,4000000 found and this one appears as the last line of output to the virtual console after shutting down the X server: waiting for X server to shut down error setting MTRR (base = 0xd0000000, \ size = 0x04000000, type = 1) Invalid argument (22) Here are the applicable kernel config lines: if the config doesn't make sense, I'm sure someone will let me know. The last time I *know* MTRRs worked properly was before the PAT and SANITIZER options showed up: yeah, that far back... CONFIG_MTRR=y CONFIG_MTRR_SANITIZER=y CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1 CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1 CONFIG_X86_PAT=y --Bob -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
