| | | | | | | | | | | | | | | | | | | | | | Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect. However, this signal has been changed to pad AG9 in board revision C2. Fix this by adding mux configuration for pad AG9, runtime check for board revisions and set the gpio number and pad muxing accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only way to flush posted write to L4 bus is to do a read back of the same register right after the write. This seems to be mostly needed in interrupt handlers to avoid causing spurious interrupts. The earlier fix has been to mark the L4 bus as strongly ordered memory, which solves the problem, but causes performance penalties.

* | pty: reconnect the BSD TIOCSPTLCK handling to legacy ptysLinus Torvalds2009-09-301-21/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | David Howells noticed (due to the compiler warning about an unused 'pty_ops_bsd' variable) that we haven't actually been using the code that implements TIOCSPTLCK for legacy pty handling. It's been that way since 2.6.26, commit 3e8e88ca053150efdbecb45d8f481cf560ec808d to be exact ("pty: prepare for tty->ops changes"). DavidH initially submitted a patch just removing the dead code entirely, and since nobody has apparently ever complained, I'm not entirely sure that wouldn't be the right thing to do. But since the whole and only point of the legacy pty code is to be compatible with legacy distros that don't use the new unix98 pty model, let's just wire it up again. And clean it up a bit while we're at it. Acked-by: David Howells <dhowells@redhat.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Fix it as per the following Alan's suggestion: Fun but it's actually not a bug and the fix is wrong in itself as the port may be closing but not yet being destructed, in which case it seems to do the wrong thing. Opening a tty that is closing (and could be closing for long periods) is supposed to return -EIO. I suspect a better way to deal with this and keep the old console timing is to split tty->shutdown into two functions. tty->shutdown() - called synchronously just before we dump the tty onto the waitqueue for destruction tty->cleanup() - called when the destructor runs. We would then do the shutdown part which can occur in IRQ context fine, before queueing the rest of the release (from tty->magic = 0 ... the end) to occur asynchronously The USB update in -next would then need a call like if (tty->cleanup) tty->cleanup(tty); at the top of the async function and the USB shutdown to be split between shutdown and cleanup as the USB resource cleanup and final tidy cannot occur synchronously as it needs to sleep. In other words the logic becomes final kref put make object unfindable async clean it up Signed-off-by: Dave Young <hidave.darkstar@gmail.com> [ rjw: Rebased on top of 2.6.31-git, reworked the changelog. ] Signed-off-by: "Rafael J.

No specific test case was required to observe this effect. This occurres because there was no check to see if the currently removed or restarted hrtimer was: 1) the one which previously armed the clock events device. 2) going to be replaced by another timer which has the same expiry time. Avoid the reprogramming in hrtimer_force_reprogram when the new expiry value which is evaluated from the clock bases is equal to cpu_base->expires_next. This results in faster application startup time by ~4%.

The device _may_ need an ACPI driver, if the BIOS implemented a custom API for the device in question (which, AFAIK, can't be checked.) If not, then either a generic ACPI driver may be used (for example "thermal"), or nothing can be done (other than a white list). I propose to reword the message to: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver which I think is more correct. Comments and suggestions welcome. I also added a message warning about possible problems and system instability when users pass acpi_enforce_resources=lax, as suggested by Len.

IA64 implementation has a couple of differences because of the available atomic operations ... e.g. we have no fetchadd2 instruction that operates on a 16-bit quantity so we make ticket locks use a 32-bit word for each of the current ticket and now-serving values. Performance on uncontended locks is about 8% worse than the previous implementation, but this seems a good trade for determinism in the contended case. Performance impact on macro-level benchmarks is in the noise. Signed-off-by: Tony Luck <tony.luck@intel.com>

The device can also autonomously control the LEDs based on a selection of sources. This can be configured at boot time using either platform data or the chip OTP. A sysfs file in the style of that for triggers allowing the control source to be configured at run time. Triggers can't be used here since they can't depend on the implementation details of a specific LED type.

Add a function to update the value in the core, and additionally send a uevent so that userspace can pop up appropriate UI. The uevents are flagged depending on whether the update originated in the kernel or from userspace, making it easier to only display UI at the appropriate time.
