2011-10-14ore/exofs: Change ore_check_io APIBoaz Harrosh
Current ore_check_io API receives a residual pointer, to report partial IO. But it is actually not used, because in a multiple devices IO there is never a linearity in the IO failure. On the other hand if every failing device is reported through a received callback measures can be taken to handle only failed devices. One at a time. This will also be needed by the objects-layout-driver for it's error reporting facility. Exofs is not currently using the new information and keeps the old behaviour of failing the complete IO in case of an error. (No partial completion) TODO: Use an ore_check_io callback to set_page_error only the failing pages. And re-dirty write pages. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore/exofs: Define new ore_verify_layoutBoaz Harrosh
All users of the ore will need to check if current code supports the given layout. For example RAID5/6 is not currently supported. So move all the checks from exofs/super.c to a new ore_verify_layout() to be used by ore users. Note that any new layout should be passed through the ore_verify_layout() because the ore engine will prepare and verify some internal members of ore_layout, and assumes it's called. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: Support for partial component tableBoaz Harrosh
Users like the objlayout-driver would like to only pass a partial device table that covers the IO in question. For example exofs divides the file into raid-group-sized chunks and only serves group_width number of devices at a time. The partiality is communicated by setting ore_componets->first_dev and the array covers all logical devices from oc->first_dev upto (oc->first_dev + oc->numdevs) The ore_comp_dev() API receives a logical device index and returns the actual present device in the table. An out-of-range dev_index will BUG. Logical device index is the theoretical device index as if all the devices of a file are present. .i.e: total_devs = group_width * mirror_p1 * group_count 0 <= dev_index < total_devs Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: Support for short read/writesBoaz Harrosh
Memory conditions and max_bio constraints might cause us to not comply to the full length of the requested IO. Instead of failing the complete IO we can issue a shorter read/write and report how much was actually executed in the ios->length member. All users must check ios->length at IO_done or upon return of ore_read/write and re-issue the reminder of the bytes. Because other wise there is no error returned like before. This is part of the effort to support the pnfs-obj layout driver. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14exofs: Support for short read/writesBoaz Harrosh
If at read/write_done the actual IO was shorter then requested, reported in returned ios->length. It is not an error. The reminder of the pages should just be unlocked but not marked uptodate or end_page_writeback. They will be re issued later by the VFS. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: Remove check for ios->kern_buff in _prepare_for_striping to laterBoaz Harrosh

2011-10-14ore: cleanup: Embed an ore_striping_info inside ore_io_stateBoaz Harrosh
Now that each ore_io_state covers only a single raid group. A single striping_info math is needed. Embed one inside ore_io_state to cache the calculation results and eliminate an extra call. Also the outer _prepare_for_striping is removed since it does nothing. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
2011-10-14ore: Only IO one group at a time (API change)Boaz Harrosh
Usually a single IO is confined to one group of devices (group_width) and at the boundary of a raid group it can spill into a second group. Current code would allocate a full device_table size array at each io_state so it can comply to requests that span two groups. Needless to say that is very wasteful, specially when device_table count can get very large (hundreds even thousands), while a group_width is usually 8 or 10. * Change ore API to trim on IO that spans two raid groups. The user passes offset+length to ore_get_rw_state, the ore might trim on that length if spanning a group boundary. The user must check ios->length or ios->nrpages to see how much IO will be preformed. It is the responsibility of the user to re-issue the reminder of the IO. * Modify exofs To copy spilled pages on to the next IO. This means one last kick is needed after all coalescing of pages is done. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>

2011-10-14xen: Fix selfballooning and ensure it doesn't go too farDan Magenheimer
The balloon driver's "current_pages" is very different from totalram_pages. Self-ballooning needs to be driven by the latter. Also, Committed_AS doesn't account for pages used by the kernel so: 1) Add totalreserve_pages to Committed_AS for the normal target. 2) Enforce a floor for when there are little or no user-space threads using memory (e.g. single-user mode) to avoid OOMs. The floor function includes a "min_usable_mb" tuneable in case we discover later that the floor function is still too aggressive in some workloads, though likely it will not be needed. Changes since version 4: - change floor calculation so that it is not as aggressive; this version uses a piecewise linear function similar to minimum_target in the 2.6.18 balloon driver, but modified to add to totalreserve_pages instead of subtract from max_pfn, the 2.6.18 version causes OOMs on recent kernels because the kernel has expanded over time - change safety_margin to min_usable_mb and comment on its use - since committed_as does NOT include kernel space (and other reserved pages), totalreserve_pages is now added to committed_as. The result is less aggressive self-ballooning, but theoretically more appropriate. Changes since version 3: - missing include causes compile problem when CONFIG_FRONTSWAP is disabled - add comments after includes Changes since version 2: - missing include causes compile problem only on 32-bit Changes since version 1: - tuneable safety margin added [v5: avi.miller@oracle.com: still too aggressive, seeing some OOMs] [v4: konrad.wilk@oracle.com: fix compile when CONFIG_FRONTSWAP is disabled] [v3: guru.anbalagane@oracle.com: fix 32-bit compile] [v2: konrad.wilk@oracle.com: make safety margin tuneable] Signed-off-by: Dan Magenheimer <dan.magenheimer@oracle.com> [v1: Altered description and added an extra include] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

2011-10-14tracing: Fix returning of duplicate data after EOF in trace_pipe_rawSteven Rostedt
The trace_pipe_raw handler holds a cached page from the time the file is opened to the time it is closed. The cached page is used to handle the case of the user space buffer being smaller than what was read from the ring buffer. The left over buffer is held in the cache so that the next read will continue where the data left off. After EOF is returned (no more data in the buffer), the index of the cached page is set to zero. If a user app reads the page again after EOF, the check in the buffer will see that the cached page is less than page size and will return the cached page again. This will cause reading the trace_pipe_raw again after EOF to return duplicate data, making the output look like the time went backwards but instead data is just repeated. The fix is to not reset the index right after all data is read from the cache, but to reset it after all data is read and more data exists in the ring buffer.

2011-10-14x86, intel: Output microcode revision in /proc/cpuinfoAndi Kleen
I got a request to make it easier to determine the microcode update level on Intel CPUs. This patch adds a new "microcode" field to /proc/cpuinfo. The microcode level is also outputed on fatal machine checks together with the other CPUID model information. I removed the respective code from the microcode update driver, it just reads the field from cpu_data. Also when the microcode is updated it fills in the new values too. I had to add a memory barrier to native_cpuid to prevent it being optimized away when the result is not used. This turns out to clean up further code which already got this information manually.
