RDMA/cxgb3: Fix regression caused by class_device -> device conversion
|
|
The change to iwch_provider.c in commit f4e91eb4 ("IB: convert struct
class_device to struct device") undid the fix done in commit 7f049f2f
("RDMA/cxgb3: Hold rtnl_lock() around ethtool get_drvinfo call"). It
removed the calls to rtnl_lock() that serialized the iw_cxgb3 ethtool
ops calls into the cxgb3 driver. This locking is needed to avoid
messing up the internal state of the cxgb3 driver.

The driver uses completely bogus rounding formula for calculating period from
the IDECLK frequency which gives one-off period values (e.g. 11 ns with 100 MHz
IDECLK) which in turn can lead to overclocked IDE transfer timings. Actually,
rounding is just wrong in this case, so use a mere division for a safe result.
While at it, also:
- give 'ide_palm_clk' variable a more suitable name;
- get rid of the useless 'ideclkp' variable;
- drop the LISP stype 'p' postfix from the 'clkp' variable's name. :-)

Add __ide_default_irq() inline helper and use it instead of
ide_default_irq() in ide-probe.c and ns87415.c (all host drivers
except IDE PCI ones always setup hwif->irq so it is enough to
check only for I/O bases 0x1f0 and 0x170).
This fixes post-2.6.25 regression since ide_default_irq()
define could shadow ide_default_irq() inline.

The pxa27x DMA controller defaults to 64-bit alignment. This caused
the SCR reads to fail (and, depending on card type, error out) when
card->raw_scr was not aligned on a 8-byte boundary.
For performance reasons all scatter-gather addresses passed to
pxamci_request should be aligned on 8-byte boundaries, but if
this can't be guaranteed, byte aligned DMA transfers in the
have to be enabled in the controller to get correct behaviour.

This reverts commit e872154921a6b5256a3c412dd69158ac0b135176.
Andrey Borzenkov reports that it resulted in a totally hung machine for
him when loading the OHCI driver. Extensive netconsole capture with
SysRq output shows that modprobe gets stuck in ohci_hub_status_data()
when probing and enabling the OHCI controller, see for example
http://lkml.org/lkml/2008/7/5/236
for an analysis.
The problem appears to be an interrupt flood triggered by the commit
that gets reverted, and Andrey confirmed that the revert makes things
work for him again.

Some Dell laptops enter resume with apparent garbage in the segment
descriptor registers (almost certainly the result of a botched
transition from protected to real mode.) The only way to clean that
up is to enter protected mode ourselves and clean out the descriptor

The CaFe chip has a hardware bug that ends up with us getting a timeout
value that's too small, causing the following sorts of problems:
[ 60.525138] mmcblk0: error -110 transferring data
[ 60.531477] end_request: I/O error, dev mmcblk0, sector 1484353
[ 60.533371] Buffer I/O error on device mmcblk0p2, logical block 181632
[ 60.533371] lost page write due to I/O error on mmcblk0p2
Presumably this is an off-by-one error in the hardware. Incrementing
the timeout count value that we stuff into the TIMEOUT_CONTROL register
gets us a value that works. This bug was originally discovered by
Pierre Ossman, I believe.
[thanks to Robert Millan for proving that this was still a problem]

This has been sitting around unloved for way too long..
The Marvell CaFe chip's SD implementation chokes during card insertion
if one attempts to set the voltage and power up in the same
SDHCI_POWER_CONTROL register write. This adds a quirk that does
that particular dance in two steps.
It also adds an entry to pci_ids.h for the CaFe chip's SD device.

This patch changes the way we determine the maximum number of outstanding
commands for each controller.
Most Smart Array controllers can support up to 1024 commands, the notable
exceptions are the E200 and E200i.
The next generation of controllers which were just added support a mode of
operation called Zero Memory Raid (ZMR). In this mode they only support
64 outstanding commands. In Full Function Raid (FFR) mode they support
1024.
We have been setting the queue depth by arbitrarily assigning some value
for each controller. We needed a better way to set the queue depth to
avoid lots of annoying "fifo full" messages. So we made the driver a
little smarter. We now read the config table and subtract 4 from the
returned value. The -4 is to allow some room for ioctl calls which are
not tracked the same way as io commands are tracked.
Please consider this for inclusion.

This got broken by the recent "fix rmmod $spi_driver while spidev-user is
active". I tested the rmmod & write path but didn't check the read path.
I am sorry. The read logic changed and spidev_sync_read() +
spidev_sync_write() do not return zero on success anymore but the number
of bytes that has been transfered over the bus. This patch changes the
logic and copy_to_user() gets called again.
The write path returns the number of bytes which are written to the
underlying device what may be less than the requested size. This patch
makes the same change to the read path or else we request a read of 20
bytes, get 10, don't call copy to user and report to the user that we read
10 bytes.

I have discovered that the current version of rtc-x1205.c does not work
correctly when asked to set the alarm time by the RTC_WKALM_SET ioctl()
call. This happens because the alarm registers do not behave like the
current-time registers. They are non-volatile. Two things go wrong:
- the X1205 requires a 10 msec delay after any attempt to write to the
non-volatile registers. The x1205_set_datetime() routine does the write
as 8 single-byte writes without any delay. Only the first write
succeeds. The second is NAKed because the chip is busy.
- the X1205 resets the RWEL bit after any write to the non-volatile
registers. This would lock out any further writes after the first even
with a 10msec delay.
I fix this by doing a single 8-byte write and then waiting 10msec for the
chip to be ready. A side effect of this change is that it will speed up
x1205_rtc_set_time() which uses the same code.
I have also implemented the 'enable' bit in the rtc_wkalm structure, which
the existing driver does not attempt to do. I have modified both
x1205_rtc_set_alarm() to set the AL0E bit, and x1205_rtc_read_alarm() to
return it.
I have tested this patch on a LinkSys NSLU2 under OpenWRT, but on no other
hardware. On the NSLU2 the X1205 correctly asserts its IRQ pin when the
alarm time matches the current time.

While 0e36a9a4a788e4e92407774df76c545910810d35 ("rtc: fix readback from
/sys/class/rtc/rtc?/wakealarm") made sure that active alarms were never
returned with invalid "wildcard" fields (negative), it can still report
(wrongly) that the alarm triggers in the past.
Example, if it's now 10am, an alarm firing at 5am will be triggered
TOMORROW not today. (Which may also be next month or next year...)
This updates that alarm handling in three ways:
* Handle alarm rollover in the common cases of RTCs that don't
support matching on all date fields.
* Skip the invalid-field logic when it's not needed.
* Minor bugfix ... tm_isdst should be ignored, it's one of the
fields Linux doesn't maintain.
A warning is emitted for some of the unhandled rollover cases, but the
possible combinations are a bit too numerous to handle every bit of
potential hardware and firmware braindamage.

Some AHCI controllers (ICH7 was reported) set pending bit in
HOST_IRQ_STAT for non-existent ports and when it's not cleared falls
into IRQ storm. Always clear full irq_stat instead of only the bits
that are handled. As nothing changes for recognized ports, the risk
of breaking things is pretty low.

multicast and promiscuous settings. This patch restores those settings at the
end of restart().

The descriptor pointers were not initialized to NIL values, so it was
poiniting to some random addresses which was completely invalid. This
fix takes care of initializing the descriptor to NIL values and clearing
the valid descriptors on clean ring operation.

iph->tot_len is stored in network byte order, so access it using
ntohs(). This doesn't have any real world impact on pasemi_mac, since
the device only exists as part of a big-endian system-on-chip, but
fixing this gets rid of a sparse warning and avoids having a bad example
in the tree.

When ehea_stop is called the function
cancel_work_sync(&port->reset_task) is used to ensure
that the reset task is not running anymore. We need an
additional flag to ensure that it can not be scheduled
after this call again for a certain time.
