2008-04-07[SCSI] st: show options currently set in sysfsKai Makisara1-1/+6
Show the current binary tape driver and mode options is sysfs. A file (options) is created in each directory in /sys/class/scsi_tape. The files contain masks showing the options. The mask bit definitions are the same as used when setting the options using the MTSETDRVBUFFER function in the MTIOCTOP ioctl (defined in include/linux/mtio.h). For example: > cat /sys/class/scsi_tape/nst0/options 0x00000d07 [jejb: updated doc with correction from Randy Dunlap] Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
2008-04-07[SCSI] st: add option to use SILI in variable block readsKai Makisara1-1/+6
Add new option MT_ST_SILI to enable setting the SILI bit in reads in variable block mode. If SILI is set, reading a block shorter than the byte count does not result in CHECK CONDITION. The length of the block is determined using the residual count from the HBA. Avoiding the REQUEST SENSE command for every block speeds up some real applications considerably.

2008-04-04cgroups: add cgroup support for enabling controllers at boot timePaul Menage1-0/+4
The effects of cgroup_disable=foo are: - foo isn't auto-mounted if you mount all cgroups in a single hierarchy - foo isn't visible as an individually mountable subsystem As a result there will only ever be one call to foo->create(), at init time; all processes will stay in this group, and the group will never be mounted on a visible hierarchy. Any additional effects (e.g. not allocating metadata) are up to the foo subsystem. This doesn't handle early_init subsystems (their "disabled" bit isn't set be, but it could easily be extended to do so if any of the early_init systems wanted it - I think it would just involve some nastier parameter processing since it would occur before the command-line argument parser had been run. Hugh said: Ballpark figures, I'm trying to get this question out rather than processing the exact numbers: CONFIG_CGROUP_MEM_RES_CTLR adds 15% overhead to the affected paths, booting with cgroup_disable=memory cuts that back to 1% overhead (due to slightly bigger struct page). I'm no expert on distros, they may have no interest whatever in CONFIG_CGROUP_MEM_RES_CTLR=y; and the rest of us can easily build with or without it, or apply the cgroup_disable=memory patches.

2008-04-01ACPI PM: Restore the 2.6.24 suspend orderingRafael J. Wysocki1-5/+0
Some time ago it turned out that our suspend code ordering broke some NVidia-based systems that hung if _PTS was executed with one of the PCI devices, specifically a USB controller, in a low power state. Then, it was noticed that the suspend code ordering was not compliant with ACPI 1.0, although it was compliant with ACPI 2.0 (and later), and it was argued that the code had to be changed for that reason (ref. http://bugzilla.kernel.org/show_bug.cgi?id=9528). So we did, but evidently we did wrong, because it's now turning out that some systems have been broken by this change. Refs: http://bugzilla.kernel.org/show_bug.cgi?id=10340 https://bugzilla.novell.com/show_bug.cgi?id=374217#c16 [ I said at that time that something like this might happend, but the majority of people involved thought that it was improbable due to the necessity to preserve the compliance of hardware with ACPI 1.0. ] This actually is a quite serious regression from 2.6.24. Moreover, the ACPI 1.0 ordering of suspend code introduced another issue that I have only noticed recently. Namely, if the suspend of one of devices fails, the already suspended devices will be resumed without executing _WAK before, which leads to problems on some systems (for example, in such situations thermal management is broken on my HP nx6325). Consequently, it also breaks suspend debugging on the affected systems. Note also, that the requirement to execute _PTS before suspending devices does not really make sense, because the device in question may be put into a low power state at run time for a reason unrelated to a system-wide suspend. For the reasons outlined above, the change of the suspend ordering should be reverted, which is done by the patch below. [ Felix Möller: "I am the reporter from the original Novell Bug: https://bugzilla.novell.com/show_bug.cgi?id=374217 I just tried current git head (two hours ago) with the patch (the one from the beginning of this thread) from Rafael and without it. With the patch my MacBook does suspend without it does not." ] Signed-off-by: Rafael J.

Update documentation for the hw_random support to be current: - Documentation/hw_random.txt has been updated to reflect the current code: it's a framework now, a "core" with a small sysfs interface, that hardware-specific drivers plug in to. Text specific to Intel hardware is now at the end. - Kconfig now references the Documentation/hw_random.txt file and better explains what this really does. Both chunks of documentation now higlight the fact that the kernel entropy pool is maintained by "rngd", and this driver has nothing directly to do with that important task.

2008-03-15ACPI: Remove ACPI_CUSTOM_DSDT_INITRD optionLinus Torvalds3-56/+2
This essentially reverts commit 71fc47a9adf8ee89e5c96a47222915c5485ac437 ("ACPI: basic initramfs DSDT override support"), because the code simply isn't ready. It did ugly things to the init sequence to populate the rootfs image early, but that just ended up showing other problems with the whole approach. The fact is, the VFS layer simply isn't initialized this early, and the relevant ACPI code should either run much later, or this shouldn't be done at all. For 2.6.25, we'll just pick the latter option. We can revisit this concept later if necessary.

The lguest launcher appends a space to the kernel command line (if kernel arguments are specified on its command line). This space is unneeded. More importantly, this appended space will make Red Hat's nash script interpreter (used in a Fedora style initramfs) add an empty argument to init's command line. This empty argument will make kernel arguments like "init=/bin/bash" fail (because the shell will try to execute a script with an empty name).

2008-03-04gpio: <linux/gpio.h> and "no GPIO support here" stubsDavid Brownell1-4/+12
Add a <linux/gpio.h> defining fail/warn stubs for GPIO calls on platforms that don't support the GPIO programming interface. That includes the arch-specific implementation glue otherwise. This facilitates a new model for GPIO usage: drivers that can use GPIOs if they're available, but don't require them. One example of such a driver is NAND driver for various FreeScale chips. On platforms update with GPIO support, they can be used instead of a worst-case delay to verify that the BUSY signal is off. (Also includes a couple minor unrelated doc updates.)

2008-03-04Memory Resource Controller use strstrip while parsing argumentsBalbir Singh1-3/+3
The memory controller has a requirement that while writing values, we need to use echo -n. This patch fixes the problem and makes the UI more consistent.

2008-03-04PCI: Add DECLARE_PCI_DEVICE_TABLE macroJonas Bonn1-2/+4
The definitions of struct pci_device_id arrays should generally follow the same pattern across the entire kernel. This macro defines this array as const and puts it into the __devinitconst section. There are currently many definitions scattered about the kernel that omit the __devinitdata modifier despite the documentation stating that it should always be there. These definitions really also should have been const, which wasn't possible before but has become so with the addition of the __devinitconst attribute. Furthermore, there are definitions that use "const" and __devinitdata, which is explicitly wrong but the compiler doesn't catch section mismatches if there's only one such one case in the module (which is often the case). Adding the __devinitconst modifier where there was nothing before buys us memory. Adding the const modifier gives the compiler a chance to do its thing. Changing __devinitdata to __devinitconst where it was wrong actually fixes some compiler errors in older (mid-release) kernels that were patched over by "removing" the section attribute altogether (which wastes memory). This macro makes it pretty difficult to get this definition wrong in the future... Signed-off-by: Jonas Bonn <jonas@southpole.se> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
