for !BSY right after that anyway.

timeouts are considered error conditions making libata fail to detect

hexdump: more output formatting

Add a prefix string parameter.  Callers are responsible for any string
length/alignment that they want to see in the output.  I.e., callers should
pad strings to achieve alignment if they want that.

Add rowsize parameter.  This is the number of raw data bytes to be printed
per line.  Must be 16 or 32.

Add a groupsize parameter.  This allows callers to dump values as 1-byte,
2-byte, 4-byte, or 8-byte numbers.  Default is 1-byte numbers.  If the
total length is not an even multiple of groupsize, 1-byte numbers are
printed.

Add an "ascii" output parameter.  This causes ASCII data output following
the hex data output.

Clean up some doc examples.

Align the ASCII output on all lines that are produced by one call.

Add a new interface, print_hex_dump_bytes(), that is a shortcut to
print_hex_dump(), using default parameter values to print 16 bytes in
byte-size chunks of hex + ASCII output, using printk level KERN_DEBUG.

We aren't sampling for holes in memory.  Thus we encounter a section hole

issue has been seen in 2.6.21, current git and current mm.  The patch below

of Andy's in mm ml and DISCONTIGMEM.  A slightly different patch will be
posted to stable for 2.6.21.

Previous to commit f0a5a58aa812b31fd9f197c4ba48245942364eae memory_present
was called for node_start_pfn to node_end_pfn.  This would cover the
hole(s) with reserved pages and valid sections.  Most SPARSEMEM supported
arches do a pfn_valid check in show_mem before computing the page structure
address.

17 years agopi-futex: fix exit races and locking problems
Alexey Kuznetsov [Fri, 8 Jun 2007 20:47:00 +0000 (13:47 -0700)]
pi-futex: fix exit races and locking problems

1. New entries can be added to tsk->pi_state_list after task completed
   exit_pi_state_list(). The result is memory leakage and deadlocks.

2. handle_mm_fault() is called under spinlock. The result is obvious.

3. results in self-inflicted deadlock inside glibc.
   Sometimes futex_lock_pi returns -ESRCH, when it is not expected
   and glibc enters to for(;;) sleep() to simulate deadlock. This problem
   is quite obvious and I think the patch is right. Though it looks like
   each "if" in futex_lock_pi() got some stupid special case "else if". :-)

4. sometimes futex_lock_pi() returns -EDEADLK,
   when nobody has the lock. The reason is also obvious (see comment
   in the patch), but correct fix is far beyond my comprehension.
   I guess someone already saw this, the chunk:

                        if (rt_mutex_trylock(&q.pi_state->pi_mutex))
                                ret = 0;

   is obviously from the same opera. But it does not work, because the
   rtmutex is really taken at this point: wake_futex_pi() of previous
   owner reassigned it to us. My fix works. But it looks very stupid.
   I would think about removal of shift of ownership in wake_futex_pi()
   and making all the work in context of process taking lock.

From: Thomas Gleixner <tglx@linutronix.de>

Fix 1) Avoid the tasklist lock variant of the exit race fix by adding
    an additional state transition to the exit code.

    This fixes also the issue, when a task with recursive segfaults
    is not able to release the futexes.

Fix 2) Cleanup the lookup_pi_state() failure path and solve the -ESRCH
    problem finally.

Fix 3) Solve the fixup_pi_state_owner() problem which needs to do the fixup
    in the lock protected section by using the in_atomic userspace access
    functions.

    This removes also the ugly lock drop / unqueue inside of fixup_pi_state()

Fix 4) Fix a stale lock in the error path of futex_wake_pi()

Added some error checks for verification.

The -EDEADLK problem is solved by the rtmutex fixups.

sata_promise: use TF interface for polling NODATA commands

sata_promise uses two different command modes - packet and TF.  Packet mode
is intelligent low-overhead mode while TF is the same old taskfile
interface.  As with other advanced interface (ahci/sil24),
ATA_TFLAG_POLLING has no effect in packet mode.  However, PIO commands are
issued using TF interface in polling mode, so pdc_interrupt() considers
interrupts spurious if ATA_TFLAG_POLLING is set.

This is broken for polling NODATA commands because command is issued using
packet mode but the interrupt handler ignores it due to ATA_TFLAG_POLLING.
Fix pdc_qc_issue_prot() such that ATA/ATAPI NODATA commands are issued
using TF interface if ATA_TFLAG_POLLING is set.

Reading the MAC address from atm_dev before atm_dev exists would have been

Calling create_device_file in atm_start will avoid this problem, and the

ready before a status poll does a printk on line status change otherwise
userspace could react before the files exist.

For completeness I've moved remove_device_file to atm_stop so it's not
called in unbind when it's not needed.  There's no point starting ADSL if

  Â  [PATCH] ide: if the id fields looks screwy, disable DMA

  Â  It's the safer choice. Originally due to a bug in itx821x, but a
  Â  generally sound thing to do.

  Â  Signed-off-by: Jens Axboe <axboe@suse.de>

However it worked by pure luck before Jens' fixes: bogus ide_dma_enable()
usage in it821x driver combined with loosy check in ide_dma_verbose() allowed
the hardware to operate in DMA mode.  When these problems were fixed the DMA
support broke...

The source root for the regression turned out to be that the it821x.c code
was clearing too much of id->field_valid.  The IDE core code was using the
original value of id->field_valid to do the tuning but later DMA got disabled
in ide_dma_verbose() because of the incorrect id->field_valid fixup.  Fix it.

While at it:

* Do fixup() after probing the drives but before tuning them (which is also
  OK w.r.t. ide_undecoded_slave() fixup).  This change fixes device IDENTIFY
  data to be consistent before/after the tuning and allows us to remove extra
  re-tuning of drives from it821x_fixups().

* Fake MWDMA0 enabled/supported bits in IDENTIFY data if the device has
  DMA capable bit set (this is just to tell the IDE core that DMA is
  supported since it821x firmware takes care of DMA mode programming).

* Don't touch timing registers and don't program transfer modes on devices
  et all when in RAID mode - depend solely on firmware to do the tuning
  (as suggested by Alan Cox and done in libata pata_it821x driver).

Thanks for testing the patch goes out to Thomas Kuther.

17 years agoserverworks: fix CSB6 tuning logic

serverworks: fix CSB6 tuning logic

Problem noticed by Joe Zbiciak, see

http://kerneltrap.org/node/8252

for details.

On CSB6 the driver is using BIOS settings and not programming DMA/PIO timings
itself.  However the logic was completely broken and resulted in wrong timings
being silently allowed (instead of being corrected by the driver).

This bug would explain some data corruption/timeout issues with Serverworks
MegaIDE in RAID mode that Alan Cox has fixed recently with:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2074a106f52b6371885afbd714e929d60d0e3f64

For 2.6.23 we may be better off with completely switching the driver to always
programming timings (libata pata_serverworks.c driver is doing things this way
and there were no problems reported so far) but for 2.6.22 lets fix the bug
in the simplest and the least intrusive way.
