While now printk is used by Linux kernel to report hardware error information to user space. So, this patch adds printing support for the data structure, so that the corresponding hardware error information can be reported to user space via printk. PCIe AER information printing is not implemented yet. Will refactor the original PCIe AER information printing code to avoid code duplicating. The output format is as follow: <error record> := APEI generic hardware error status severity: <integer>, <severity string> section: <integer>, severity: <integer>, <severity string> flags: <integer> <section flags strings> fru_id: <uuid string> fru_text: <string> section_type: <section type string> <section data> <severity string>* := recoverable | fatal | corrected | info <section flags strings># := [primary][, containment warning][, reset][, threshold exceeded]\ [, resource not accessible][, latent error] <section type string> := generic processor error | memory error | \ PCIe error | unknown, <uuid string> <section data> := <generic processor section data> | <memory section data> | \ <pcie section data> | <null> <generic processor section data> := [processor_type: <integer>, <proc type string>] [processor_isa: <integer>, <proc isa string>] [error_type: <integer> <proc error type strings>] [operation: <integer>, <proc operation string>] [flags: <integer> <proc flags strings>] [level: <integer>] [version_info: <integer>] [processor_id: <integer>] [target_address: <integer>] [requestor_id: <integer>] [responder_id: <integer>] [IP: <integer>] <proc type string>* := IA32/X64 | IA64 <proc isa string>* := IA32 | IA64 | X64 <processor error type strings># := [cache error][, TLB error][, bus error][, micro-architectural error] <proc operation string>* := unknown or generic | data read | data write | \ instruction execution <proc flags strings># := [restartable][, precise IP][, overflow][, corrected] <memory section data> := [error_status: <integer>] [physical_address: <integer>] [physical_address_mask: <integer>] [node: <integer>] [card: <integer>] [module: <integer>] [bank: <integer>] [device: <integer>] [row: <integer>] [column: <integer>] [bit_position: <integer>] [requestor_id: <integer>] [responder_id: <integer>] [target_id: <integer>] [error_type: <integer>, <mem error type string>] <mem error type string>* := unknown | no error | single-bit ECC | multi-bit ECC | \ single-symbol chipkill ECC | multi-symbol chipkill ECC | master abort | \ target abort | parity error | watchdog timeout | invalid address | \ mirror Broken | memory sparing | scrub corrected error | \ scrub uncorrected error <pcie section data> := [port_type: <integer>, <pcie port type string>] [version: <integer>.<integer>] [command: <integer>, status: <integer>] [device_id: <integer>:<integer>:<integer>.<integer> slot: <integer> secondary_bus: <integer> vendor_id: <integer>, device_id: <integer> class_code: <integer>] [serial number: <integer>, <integer>] [bridge: secondary_status: <integer>, control: <integer>] <pcie port type string>* := PCIe end point | legacy PCI end point | \ unknown | unknown | root port | upstream switch port | \ downstream switch port | PCIe to PCI/PCI-X bridge | \ PCI/PCI-X to PCIe bridge | root complex integrated endpoint device | \ root complex event collector Where, [] designate corresponding content is optional All <field string> description with * has the following format: field: <integer>, <field string> Where value of <integer> should be the position of "string" in <field string> description.

First, update the feature-removal-schedule to announce this change. Second, add runtime warnings in ACPI AC/Battery/SBS driver, so that users will notice this change even if "make oldconfig" is used.

* | | | | | oom: allow a non-CAP_SYS_RESOURCE proces to oom_score_adj downMandeep Singh Baines2011-01-141-0/+4

Currently, it is not possible to oom_adj down without CAP_SYS_RESOURCE. This patch allows a task to decrease its oom_score_adj back to the value that a CAP_SYS_RESOURCE thread set it to or its inherited value at fork. Assuming the thread that has forked it has oom_score_adj of 0, each process could decrease it back from 0 upon activation unless a CAP_SYS_RESOURCE thread elevated it to something higher. Alternative considered: * a setuid binary * a daemon with CAP_SYS_RESOURCE Since you don't wan't all processes to be able to reduce their oom_adj, a setuid or daemon implementation would be complex. The alternatives also have much higher overhead. This patch updated from original patch based on feedback from David Rientjes.

The CTR table looks like the following: 1: <s> <l> raid \ 2: <raid_type> <#raid_params> <raid_params> \ 3: <#raid_devs> <meta_dev1> <dev1> .. <meta_devN> <devN> Line 1 contains the standard first three arguments to any device-mapper target - the start, length, and target type fields. The target type in this case is "raid". Line 2 contains the arguments that define the particular raid type/personality/level, the required arguments for that raid type, and any optional arguments. Possible raid types include: raid4, raid5_la, raid5_ls, raid5_rs, raid6_zr, raid6_nr, and raid6_nc. (again, raid1 is planned for the future.) The list of required and optional parameters is the same for all the current raid types. The required parameters are positional, while the optional parameters are given as key/value pairs. The possible parameters are as follows: <chunk_size> Chunk size in sectors. [[no]sync] Force/Prevent RAID initialization [rebuild <idx>] Rebuild the drive indicated by the index [daemon_sleep <ms>] Time between bitmap daemon work to clear bits [min_recovery_rate <kB/sec/disk>] Throttle RAID initialization [max_recovery_rate <kB/sec/disk>] Throttle RAID initialization [max_write_behind <value>] See '-write-behind=' (man mdadm) [stripe_cache <sectors>] Stripe cache size for higher RAIDs Line 3 contains the list of devices that compose the array in metadata/data device pairs. If the metadata is stored separately, a '-' is given for the metadata device position. If a drive has failed or is missing at creation time, a '-' can be given for both the metadata and data drives for a given position. Examples: # RAID4 - 4 data drives, 1 parity # No metadata devices specified to hold superblock/bitmap info # Chunk size of 1MiB # (Lines separated for easy reading) 0 1960893648 raid \ raid4 1 2048 \ 5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81 # RAID4 - 4 data drives, 1 parity (no metadata devices) # Chunk size of 1MiB, force RAID initialization, # min recovery rate at 20 kiB/sec/disk 0 1960893648 raid \ raid4 4 2048 min_recovery_rate 20 sync\ 5 - 8:17 - 8:33 - 8:49 - 8:65 - 8:81 Performing a 'dmsetup table' should display the CTR table used to construct the mapping (with possible reordering of optional parameters). Performing a 'dmsetup status' will yield information on the state and health of the array. The output is as follows: 1: <s> <l> raid \ 2: <raid_type> <#devices> <1 health char for each dev> <resync_ratio> Line 1 is standard DM output. Line 2 is best shown by example: 0 1960893648 raid raid4 5 AAAAA 2/490221568 Here we can see the RAID type is raid4, there are 5 devices - all of which are 'A'live, and the array is 2/490221568 complete with recovery.

This patch extends mapping table to optional keycount and implements generic multi-key capability. With more keys defined the <key> string is divided into several <keycount> sections and these are used for tfms. The tfm is used according to sector offset (sector 0->tfm[0], sector 1->tfm[1], sector N->tfm[N modulo keycount]) (only power of two values supported for keycount here). Because of tfms per-cpu allocation, this mode can be take a lot of memory on large smp systems.

But the flip side is that blkio controller can not be used with libvirt as libvirt creates a cgroup hierarchy deeper than 1 level. <top-level-cgroup-dir>/<controller>/libvirt/qemu/<virtual-machine-groups> o So this patch will allow creation of cgroup hierarhcy but at the backend everything will be treated as flat. So if somebody created a an hierarchy like as follows. root / \ test1 test2 | test3 CFQ and throttling will practically treat all groups at same level. pivot / | \ \ root test1 test2 test3 o Once we have actual support for hierarchical accounting and control then we can introduce another cgroup tunable file "blkio.use_hierarchy" which will be 0 by default but if user wants to enforce hierarhical control then it can be set to 1. This way there should not be any ABI problems down the line. o The only not so pretty part is introduction of extra file "use_hierarchy" down the line. Kame-san had mentioned that hierarhical accounting is expensive in memory controller hence they keep it off by default. I suspect same will be the case for IO controller also as for each IO completion we shall have to account IO through hierarchy up to the root. if yes, then it probably is not a very bad idea to introduce this extra file so that it will be used only when somebody needs it and some people might enable hierarchy only in part of the hierarchy. o This is how basically memory controller also uses "use_hierarhcy" and they also allowed creation of hierarchies when actual backend support was not available.
