hey. I'm working on a patch to add support to ipmi-locate code to parse ACPI SPMI tables via sysfs. This is to make ipmi-locate work on an ARM system we have that describes its BMC only in ACPI (not DMI). Being ARM, trolling /dev/mem isn't safe, (freeipmi ifdef's that out), so using the kernel-exposed tables, when available, is a better option.
While doing this I ran across what seems like a bug, which the following patch should fix. I say "seems" and "should" because I don't have a system where the existing /dev/mem snooping code works - with, or without this bug fix - therefore, I cannot emperically demonstrate the bug. On the systems I've tested, which do include an SPMI table, ipmi-locate is unable to find a valid RSDT signature using the /dev/mem method. I'm not sure what I'm doing wrong there - I tried diabling CONFIG_STRICT_DEVMEM andsetting the vm.mmap_min_addr sysctl to 0 w/o luck. dann frazier (1): Don't try to separate the header from the ACPI table data libfreeipmi/locate/ipmi-locate-acpi-spmi.c | 33 +++------------------- 1 file changed, 4 insertions(+), 29 deletions(-) -- 2.18.0 _______________________________________________ Freeipmi-devel mailing list Freeipmi-devel@gnu.org https://lists.gnu.org/mailman/listinfo/freeipmi-devel
