A driver for laptop buttons using an x86 BIOS interface that is
apparently used on quite a few laptops and seems to be originating
from Wistron.
This driver currently "knows" only about Fujitsu-Siemens Amilo Pro V2000
(i.e. it can detect the laptop using DMI and it contains the
keycode->key meaning mapping for this laptop) and Xeron SonicPro X 155G
(probably can't be reliably autodetected, requires a module parameter),
adding other laptops should be easy.
In addition to reporting button presses to the input layer the driver
also allows enabling/disabling the embedded wireless NIC (using the
"Wifi" button); this is done using the same BIOS interface, so it seems
only logical to keep the implementation together. Any flexibility
possibly gained by allowing users to remap the function of the "Wifi"
button is IMHO not worth it when weighted against the necessity to run
an user-space daemon to convert button presses to wifi state changes.

The way the hardware and firmware work is that there is one shared RX
queue and IRQ for a number of different network interfaces. Due to this,
we would like to process received packets for every interface in the same
NAPI poll handler, so we need a pseudo-device to schedule polling on.
What the driver currently does is that it always schedules polling for
the first network interface in the list, and processes packets for every
interface in the poll handler for that first interface -- however, this
scheme breaks down if the first network interface happens to not be up,
since netif_rx_schedule_prep() checks netif_running().
sky2 apparently has the same issue, and Stephen Hemminger suggested a
way to work around this: create a variant of netif_rx_schedule_prep()
that does not check netif_running(). I implemented this locally and
called it netif_rx_schedule_prep_notup(), and it seems to work well,
but it's something that probably not everyone would be happy with.
The ixp2000 is an ARM CPU with a high-speed network interface in the
CPU itself (full duplex 4Gb/s or 10Gb/s depending on the IXP model.)
The CPU package also contains 8 or 16 (again depending on the IXP
model) 'microengines', which are somewhat primitive but very fast
and efficient processor cores which can be used to offload various
things from the main CPU.
This driver makes the high-speed network interface in the CPU visible
and usable as a regular linux network device. Currently, it only
supports the Radisys ENP2611 IXP board, but adding support for other
board types should be fairly easy.

For the four versions of hardware that we (currently) support microcode

microcode was too aggressive, and caused unnecessary delays when pinging,

This code adds microcode support, and sets the defaults to more reasonable

Compile and load tested, shows expected behavior for slight delay of ping
packets (1-2ms) when ucode is loaded, and decent interrupt moderation for

I think 10k * 1us should be more than enough.
I tried to convert both restart and reset to use msleep's with work
queue, but if we do that, host_set lock should be released after
initiating restart or reset, leading to race condition among
reset/restart, other interrupts and timeout. Implementing
synchronization among those in low-level driver doesn't seem right.

The smc91x driver relies upon register bank 2 being selected whenever
the interrupt handler is called. This isn't always so, especially if
we have a link change event during PHY configuration.
This results in register bank 0 being selected when the interrupt
handler is called, causing the wrong registers to be read for the
IRQ mask and status. In turn, this causes us to spin with a
permanently asserted IRQ.
The patch ensures that smc_phy_configure always exits with register
bank 2 selected.

md needs to monitor the rate of requests to its devices when doing
resync/recovery so that it can back-off when there is non-resync IO. It
does this by comparing resync IO, which it counts, with total IO which is
taken from disk_stats.
disk_stats were recently changed to account sectors when a request
completes instead of when it is queued. This upsets md's calculations.
We could do the sync_io accounting at the end of requests too, but that has
problems. If an underlying device is an md array, the accounting will
still be done when the request is submitted. This could be changed for
some raid levels, but it cannot be changed for raid0 or linear without
substantial code changes.
So instead, we increase the error that is_mddev_idle allows, up to the
maximum amount of resync IO that can be in flight at any time. The
calculation is current fragile as each personality as different limits for
in-flight resync. This should be fixed up.
For now, this simple patch fixes the problem.
Increasing the error margin decreases the sensitivity to non-resync IO. To
partially compensate for this, the time to wait when non-resync IO is
detected is increased so that less steady IO is required to keep the resync
at bay.

This commit is in response to a bug reported by Vesa on the irc channel
a couple of weeks ago.
The bug was that the console would apparently hang (not return) while
using the mux console.
The root cause of this bug is that bash (with readline support) makes a
call to the tcsetattr() glibc function with the argument TCSADRAIN. This
causes the serial core in the kernel use the uart_wait_until_sent() to be
called. This function verifies the mux transmit queue is empty or calls the
msleep_interruptable() with a calculated timeout value that is dependant
upon the port->timeout variable.
The real problem here is that the port->timeout was not defined so it
was defaulted to 0 and the timeout calculation performs the following
calculation:
char_time = (port->timeout - HZ/50) / port->fifosize;
where char_time is an unsigned long. Since the serial Mux does not use
interrupts, the msleep_interruptable() function waits until the timeout
has been reached ... and when the port->timeout < HZ/50 this timeout will
be a long time. (I have validated that the console will eventually
return ... but it takes quite a while for this to happen).
This patch simply sets the port->timeout on the Mux to HZ/50 to avoid
this long timeout period.

multiplied the error log number _twice_ by the size of the error element
entry (once explicitly in the code, and once implicitly as part of the
regular pointer arithmetic).

The function ipw_request_direct_scan() should bail out when the device
is down. This fixes a lockup caused by wpa_supplicant triggering
ipw_request_direct_scan() while the driver was in a middle of a reset
due to firmware errors.
Thanks to Zilvinas Valinskas for reporting the bug and helping me
debug it.

Handle errata (it was unintentional on this h/w, whereas its intentional
on others) whereby the nIEN bit in Device Control is ignored, leading to
a situation where a hardware interrupt completes the qc before the
polling code has a chance to.
This will get fixed The Right Way(tm) once Albert Lee's irq-pio
branch is merged, as the more natural PIO method on this hardware is
interrupt-driven.
- DMA boundary was being handled incorrectly. Copied the code from
ata_fill_sg(), since Marvell has the same DMA boundary needs.
(we can't use ata_fill_sg directly since we have different hardware
descriptors)
- cleaned up the SATA phy reset code, to deal with various errata
This fixes a problem with offb not parsing addresses properly on 64 bits
machines, and thus crashing at boot. The problem is worked around by
locating the matching PCI device and using the properly relocated PCI
base addresses instead of misparsing the Open Firmware properties.

I wanted to remove the #include "hostap_ioctl.c" from hostap.c and
build hostap_ioctl.c separately, but this doesn't work since hostap.c
has the same name as the module.
After renaming hostap.c this will be possible.

As we are currently unable to fix the problem with carrier and protocol
state signaling in net core I've to disable netif_carrier_off()
calls used by WAN protocol drivers. The attached patch should make
them working again.
The remaining netif_carrier_*() calls in hdlc_fr.c are fine as they
don't touch the physical device.

ATA devices don't generate many errors, so the preferred method is to
printk() when they occur.
ATAPI devices generate tons of exceptions during the normal course
of operation, so this change skips logging the most common class of
errors.
The following code segment is not functional because the transfer cycle time speficied by
the EIDE device is later overwritten by ata_timing_quantize():
/*
* If the drive is an EIDE drive, it can tell us it needs extended
* PIO/MW_DMA cycle timing.
*/
if (adev->id[ATA_ID_FIELD_VALID] & 2) { /* EIDE drive */
memset(&p, 0, sizeof(p));
(snip)
ata_timing_merge(&p, t, t, ATA_TIMING_CYCLE | ATA_TIMING_CYC8B);
<== uninitialized "t" is used here
}
/*
* Convert the timing to bus clock counts.
*/
ata_timing_quantize(s, t, T, UT); <== t is overwritten by quantized s
The patch has been submitted for ide-timing.h before:
http://marc.theaimsgroup.com/?l=linux-ide&m=110820013425454&w=2
Resubmitted for libata.
Changes:
- Minor fix to honor the following transfer cycle time speficied by the device
- id[65]: Minimum Multiword DMA transfer cycle time per word
- id[67]: Minimum PIO transfer cycle time without flow control
- id[68]: Minimum PIO transfer cycle time with IORDY
