Usually, we found that this interface\n works well, but in some cases, when the system was taking large numbers of\n machine check exceptions, the read() would hang. The system would output a\n soft-lockup warning, and the daemon reading from /dev/mcelog would suck up\n as much of a single CPU as it could spinning in system space.\n\nDescription:\n This patch fixes this bug. In particular, there was a \"continue\" inside a\n timeout loop that presumably was intended to break out of the outer loop,\n but instead caused the inner loop to continue. This patch also makes the\n condition for the break-out a little more evident by changing a\n !time_before to a time_after_eq.\n\nResult:\n The read() no longer hangs in this test case.\n\nTesting:\n On my system, I could replicate the bug with the following command:\n # for i in `seq 15000`; do ./inject_sbe.sh; done\n where inject_sbe.sh contains commands to inject a single-bit error into the\n next memory write transaction.\n\nPatch:\n This patch is against git f1518a088bde6aea49e7c472ed6ab96178fcba3e.\n\nSigned-off-by: Joshua Wise \u003cjwise@google.com\u003e\nSigned-off-by: Tim Hockin \u003cthockin@google.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "75154f402ef18e459ff97ddece25656b6c2b329c", "tree": "6757b77ee2c712c4b64f334ff8c5b1a41a64083b", "parents": [ "e2f1f19272f8de0374ad297b9806f8b6509e0013" ], "author": { "name": "Andi Kleen", "email": "ak@suse.de", "time": "Sat Jun 23 02:29:25 2007 +0200" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Jun 22 18:41:19 2007 -0700" }, "message": "x86_64: Ignore compat mode SYSCALL when IA32_EMULATION is not defined\n\nPreviously a program could switch to a compat mode segment and then\nexecute SYSCALL and it would jump to an uninitialized MSR and crash\nthe kernel.\n\nInstead supply a dummy target for this case.\n\nPointed out by Jan Beulich\n\nCc: jbeulich@novell.com\nSigned-off-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "0864a4e201b1ea442f4c8b887418a29f67e24d30", "tree": "cee5372bb22502e52029543dfb72c571a1e89faa", "parents": [ "79d9a72f87d0a6f910be262a9dd4c36e96972a92" ], "author": { "name": "Arjan van de Ven", "email": "arjan@infradead.org", "time": "Wed Jun 20 22:23:21 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Jun 21 16:02:50 2007 -0700" }, "message": "Allow DEBUG_RODATA and KPROBES to co-exist\n\nDo not mark the kernel text read only if KPROBES is in the kernel;\nkprobes needs to hot-patch the kernel text to insert it\u0027s\ninstrumentation.\n\nIn this case, only mark the .rodata segment as read only.\n\nSigned-off-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nTested-by: S.

The implementation has some flaws though. The major\nproblem is that presence of a boot console makes register_console() ignore\nany other console devices (unless explicitly specified on the kernel\ncommand line).\n\nThis patch fixes the console selection code to *not* consider a boot\nconsole a full-featured one, so the first non-boot console registering will\nbecome the default console instead. This way the unregister call for the\nboot console in the register_console() function actually triggers and the\nhandover from the boot console to the real console device works smoothly.\nAdded a printk for the handover, so you know which console device the\noutput goes to when the boot console stops printing messages.\n\nThe disable_early_printk() call is obsolete with that patch, explicitly\ndisabling the early console isn\u0027t needed any more as it works automagically\nwith that patch.\n\nI\u0027ve walked through the tree, dropped all disable_early_printk() instances\nfound below arch/ and tagged the consoles with CON_BOOT if needed.

That fixes the bugs this patch introduced,\nand we can do the fairly obvious cleanups later.\n\nDo the new __phys_addr() function (which is now the actual workhorse for\nthe unified __pa()/__pa_symbol()) as a real external function, that way\nall the potential issues with compile/link-time optimizations of\nconstant symbol addresses go away, and we can also, if we choose to, add\nmore sanity-checking of the argument.\n\nCc: Eric W.

The\n current MCE poller uses a static interval which does not care whether it\n has or has not found MCEs recently.\n\nDescription:\n This patch makes the MCE poller adjust the polling interval dynamically.\n If we find an MCE, poll 2x faster (down to 10 ms). When we stop finding\n MCEs, poll 2x slower (up to check_interval seconds). The check_interval\n tunable becomes the max polling interval. The \"Machine check events\n logged\" printk() is rate limited to the check_interval, which should be\n identical behavior to the old functionality.\n\nResult:\n If you start to take a lot of correctable errors (not exceptions), you\n log them faster and more accurately (less chance of overflowing the MCA\n registers). If you don\u0027t take a lot of errors, you will see no change.\n\nAlternatives:\n I considered simply reducing the polling interval to 10 ms immediately\n and keeping it there as long as we continue to find errors. This felt a\n bit heavy handed, but does perform significantly better for the default\n check_interval of 5 minutes (we\u0027re using a few seconds when testing for\n DRAM errors). I could be convinced to go with this, if anyone felt it\n was not too aggressive.\n\nTesting:\n I used an error-injecting DIMM to create lots of correctable DRAM errors\n and verified that the polling interval accelerates.

Generally, this means that identical\nvalues are written to the MTRRs used by the processors.\" (short omission here)\n\"Failure to do so may result in coherency violations or loss of atomicity.\nProcessor implementations do not check the MTRR settings in other processors\nto ensure consistency. It is the responsibility of system software to\ninitialize and maintain MTRR consistency across all processors.\"\n\nCurrent Linux MTRR code already implements the above in the case that the\nBIOS does not properly initialize MTRRs on the secondary processors,\nbut the case where the fixed-range MTRRs of the boot processor are changed\nafter Linux started to boot, before the initialsation of a secondary\nprocessor, is not handled yet.\n\nIn this case, secondary processors are currently initialized by Linux\nwith MTRRs which the boot processor had very early, when mtrr_bp_init()\ndid run, but not with the MTRRs which the boot processor uses at the\ntime when that secondary processors is actually booted,\ncausing differing MTRR contents on the secondary processors.\n\nSuch situation happens on Acer Ferrari 1000 and 5000 notebooks where the\nBIOS enables and sets AMD-specific IORR bits in the fixed-range MTRRs\nof the boot processor when it transitions the system into ACPI mode.\nThe SMI handler of the BIOS does this in SMM, entered while Linux ACPI\ncode runs acpi_enable().\n\nOther occasions where the SMI handler of the BIOS may change bits in\nthe MTRRs could occur as well. To initialize newly booted secodary\nprocessors with the fixed-range MTRRs which the boot processor uses\nat that time, this patch saves the fixed-range MTRRs of the boot\nprocessor before new secondary processors are started. When the\nsecondary processors run their Linux initialisation code, their\nfixed-range MTRRs will be updated with the saved fixed-range MTRRs.\n\nIf CONFIG_MTRR is not set, we define mtrr_save_state\nas an empty statement because there is nothing to do.\n\nPossible TODOs:\n\n*) CPU-hotplugging outside of SMP suspend/resume is not yet tested\n with this patch.\n\n*) If, even in this case, an AP never runs i386/do_boot_cpu or x86_64/cpu_up,\n then the calls to mtrr_save_state() could be replaced by calls to\n mtrr_save_fixed_ranges(NULL) and mtrr_save_state() would not be\n needed.\n\n That would need either verification of the CPU-hotplug code or\n at least a test on a \u003e2 CPU machine.\n\n*) The MTRRs of other running processors are not yet checked at this\n time but it might be interesting to syncronize the MTTRs of all\n processors before booting.
