* mm: fix handling of panic_on_oom when cpusets are in useYasunori Goto2007-05-07
| | | | | | | | | | | | | | | | | | The current panic_on_oom may not work if there is a process using cpusets/mempolicy, because other nodes' memory may remain. But some people want failover by panic ASAP even if they are used. This patch makes new setting for its request. This is tested on my ia64 box which has 3 nodes.

* smaps: add clear_refs file to clear referenceDavid Rientjes2007-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds /proc/pid/clear_refs. When any non-zero number is written to this file, pte_mkold() and ClearPageReferenced() is called for each pte and its corresponding page, respectively, in that task's VMAs. This file is only writable by the user who owns the task. It is now possible to measure _approximately_ how much memory a task is using by clearing the reference bits with echo 1 > /proc/pid/clear_refs and checking the reference count for each VMA from the /proc/pid/smaps output at a measured time interval. For example, to observe the approximate change in memory footprint for a task, write a script that clears the references (echo 1 > /proc/pid/clear_refs), sleeps, and then greps for Pgs_Referenced and extracts the size in kB. Add the sizes for each VMA together for the total referenced footprint. Moments later, repeat the process and observe the difference. For example, using an efficient Mozilla: accumulated time referenced memory ---------------- ----------------- 0 s 408 kB 1 s 408 kB 2 s 556 kB 3 s 1028 kB 4 s 872 kB 5 s 1956 kB 6 s 416 kB 7 s 1560 kB 8 s 2336 kB 9 s 1044 kB 10 s 416 kB This is a valuable tool to get an approximate measurement of the memory footprint for a task.

* add new_id to PCMCIA driversBernhard Walle2007-05-07
| | | | | | | | | | | | | | | | | | | PCI drivers have the new_id file in sysfs which allows new IDs to be added at runtime. The advantage is to avoid re-compilation of a driver that works for a new device, but it's ID table doesn't contain the new device. This mechanism is only meant for testing, after the driver has been tested successfully, the ID should be added in source code so that new revisions of the kernel automatically detect the device. The implementation follows the PCI implementation. The interface is documented in Documentation/pcmcia/driver.txt. Computations should be done in userspace, so the sysfs string contains the raw structure members for matching.

CKEN24_CAMERA --> CKEN_CAMERA The reasons for the change of these defitions are: 1. they do not scale - they are currently valid for pxa2xx, but definitely not valid for pxa3xx, e.g., pxa3xx has bit 3 for camera instead of bit 24 2. they are unnecessary - the peripheral name within the definition has already announced its usage, we don't need those bit numbers to know which peripheral we are going to enable/disable clock for 3. they are inconvenient - think about this: a driver programmer for pxa has to remember which bit in the CKEN register to turn on/off Another change in the patch is to make the definitions equal to its clock bit index, so that #define CKEN_CAMERA (24) instead of #define CKEN_CAMERA (1 << 24) this change, however, will add a run-time bit shift operation in pxa_set_cken(), but the benefit of this change is that it scales when bit index exceeds 32, e.g., pxa3xx has two registers CKENA and CKENB, totally 64 bit for this, suppose CAMERA clock enabling bit is CKENB:10, one can simply define CKEN_CAMERA to be (32 + 10) and so that pxa_set_cken() need minimum change to adapt to that.

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

This patch allows you to enable COMPAT_VDSO mode with "vdso=2" on the kernel command line, or via sysctl. (Switching on a running system shouldn't be done lightly; any process which was relying on the compat VDSO will be upset if it goes away.) The COMPAT_VDSO config option still exists, but if enabled it just makes vdso_enabled default to VDSO_COMPAT. +From: Hugh Dickins <hugh@veritas.com> Fix oops from i386-make-compat_vdso-runtime-selectable.patch. Even mingetty at system startup finds it easy to trigger an oops while reading /proc/PID/maps: though it has a good hold on the mm itself, that cannot stop exit_mm() from resetting tsk->mm to NULL. (It is usually show_map()'s call to get_gate_vma() which oopses, and I expect we could change that to check priv->tail_vma instead; but no matter, even m_start()'s call just after get_task_mm() is racy.)

The benefit of knowing the length is that users can be warned if the command line size is too long which prevents surprise if things don't work after bootup. This patch updates the boot protocol to contain a field called "cmdline_size" that contain the length of the command line (excluding the terminating zero). The patch also adds missing fields (of protocol version 2.05) to the x86_64 setup code.

These nodes can be used in conjunction with cpusets for coarse memory resource management. The old command-line option is still supported: numa=fake=32 gives 32 fake NUMA nodes, ignoring the NUMA setup of the actual machine. But now you may configure your system for the node sizes of your choice: numa=fake=2*512,1024,2*256 gives two 512M nodes, one 1024M node, two 256M nodes, and the rest of system memory to a sixth node. The existing hash function is maintained to support the various node sizes that are possible with this implementation. Each node of the same size receives roughly the same amount of available pages, regardless of any reserved memory with its address range. The total available pages on the system is calculated and divided by the number of equal nodes to allocate. These nodes are then dynamically allocated and their borders extended until such time as their number of available pages reaches the required size. Configurable node sizes are recommended when used in conjunction with cpusets for memory control because it eliminates the overhead associated with scanning the zonelists of many smaller full nodes on page_alloc().

It is possible to add a new ID with only the vendor ID set, causing the driver to attempt to attach to all PCI devices from that vendor. This has been reported to happen accidentally: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-March/019366.html It is even possible to not even set the vendor ID field, causing the driver to attempt to attach to _all_ the PCI devices. This sounds dangerous and I fail to see any valid use of this "feature". Thus I suggest that we now require at least the first two fields (vendor ID and device ID) to be set. For what it's worth, this is what the USB subsystem does. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Instead, set the class of i2c_adapter.dev to i2c_adapter_class, so that a symlink will be created for every i2c_adapter in /sys/class/i2c-adapter. The same change must be mirrored to i2c-isa as it duplicates some of the i2c-core functionalities. User-space tools and libraries might need some adjustments. In particular, libsensors from lm_sensors 2.10.3 or later is required for proper discovery of i2c adapter names after this change. Signed-off-by: Jean Delvare <khali@linux-fr.org>
