15 years agopty_write: don't do a tty_wakeup() when the buffers are full
Linus Torvalds [Fri, 18 Sep 2009 14:05:58 +0000 (07:05 -0700)]
pty_write: don't do a tty_wakeup() when the buffers are full

Commit ac89a9174 ("pty: don't limit the writes to 'pty_space()' inside
'pty_write()'") removed the pty_space() checking, in order to let the
regular tty buffer code limit the buffering itself.

That was all good, but as a subtle side effect it meant that we'd be
doing a tty_wakeup() even in the case where the buffers were all filled
up, and didn't actually make any progress on the write.

Which sounds innocuous, but it interacts very badly with the ppp_async
code, which has an infinite loop in ppp_async_push() that tries to push
out data to the tty.  When we call tty_wakeup(), that loop ends up
thinking that progress was made (see the subtle interactions between
XMIT_WAKEUP and 'tty_stuffed' for details).  End result: one unhappy ppp
user.

Fixed by noticing when tty_insert_flip_string() didn't actually do
anything, and then not doing any more processing (including, very much
not calling tty_wakeup()).

Suresh Siddha [Wed, 16 Sep 2009 21:28:03 +0000 (14:28 -0700)]
x86, pat: don't use rb-tree based lookup in reserve_memtype()

Recent enhancement of rb-tree based lookup exposed a  bug with the lookup
mechanism in the reserve_memtype() which ensures that there are no conflicting
memtype requests for the memory range.

memtype_rb_search() returns an entry which has a start address <= new start
address. And from here we traverse the linear linked list to check if there
any conflicts with the existing mappings. As the rbtree is based on the
start address of the memory range, it is quite possible that we have several
overlapped mappings whose start address is much less than new requested start
but the end is >= new requested end. This results in conflicting memtype
mappings.

Same bug exists with the old code which uses cached_entry from where
we traverse the linear linked list. But the new rb-tree code exposes this
bug fairly easily.

For now, don't use the memtype_rb_search() and always start the search from
the head of linear linked list in reserve_memtype(). Linear linked list
for most of the systems grow's to few 10's of entries(as we track memory type
of RAM pages using struct page). So we should be ok for now.

We still retain the rbtree and use it to speed up free_memtype() which
doesn't have the same bug(as we know what exactly we are searching for
in free_memtype).

Also use list_for_each_entry_from() in free_memtype() so that we start
the search from rb-tree lookup result.

pata_amd: do not filter out valid modes in nv_mode_filter

On a Compaq Presario V3000 laptop (NVIDIA MCP51 chipset), pata_amd selects
PIO0 mode for the PATA DVD-RAM drive instead of MWDMA2 which it supports:

ata4.00: ATAPI: HL-DT-ST DVDRAM GSA-4084N, KQ09, max MWDMA2
ata4: nv_mode_filter: 0x39f&0x7001->0x1, BIOS=0x0 (0x0) ACPI=0x7001 (60:600:0x11)
ata4.00: configured for PIO0

For some reason, the BIOS-set UDMA configuration returns 0 and the ACPI _GTM
reports that UDMA2 and PIO0 are enabled. This causes nv_mode_filter to end up
allowing only PIO0 and UDMA0-2. Since the drive doesn't support UDMA we end up
using PIO0.

Since the controllers should always support PIO4, MWDMA2 and UDMA2 regardless
of what cable type is used, let's make sure we don't filter out these modes
regardless of what wacky settings the BIOS is using.

15 years agosata_promise: update reset code

sata_promise: update reset code

sata_promise's reset code has deviated quite a bit from
the Promise reference driver's, and it has been observed
to fail to recover from errors in some cases.

This patch thus updates the reset code to more closely
match the reference driver:

- soft reset (pdc_reset_port):
  * wait for ATA engine to not be in packet command mode
    (2nd gen only)
  * write reset bit in PDC_CTLSTAT before the first read
    in the loop
  * for 2nd gen SATA follow up with FPDMA reset and clearing
    error status registers
- hard reset (pdc_sata_hardreset):
  * wait for ATA engine to not be in packet command mode
    (2nd gen only)
  * reset ATA engine via the PCI control register
  * Tejun's change to use non-waiting hardreset + follow-up SRST

I'm not changing the hotplug mask bits since they are taken care
of by sata_promise's ->freeze() and ->thaw() operations. And I'm
not writing the PMP port # because that's always zero (for now).

Tested here on various controllers. In particular, one disk
which used to timeout and fail to recover from certain hdparm
and smartmonctl commands now works nicely.

ahci doesn't seem to be the right place to be tweaking it if it were.
This was largely okay but there are exceptions.  There was one on an

reports it on a HP DL320.

  http://bugzilla.kernel.org/show_bug.cgi?id=14124

I still think this isn't something libata drivers should be caring
about (the only ones which are calling pci_intx() explicitly are
libata ones and one other driver) but for now reverting the change

tracing: switch function prints from %pf to %ps

For direct function pointers (like what mcount provides) PowerPC64

vsprintf: add %ps that is the same as %pS but is like %pf

On PowerPC64 function pointers do not point directly at the functions,
but instead point to pointers to the functions. The output of %pF expects
to point to a pointer to the function, whereas %pS will show the function
itself.

mcount returns the direct pointer to the function and not the pointer to
the pointer. Thus %pS must be used to show this. The function tracer
requires printing of the functions without offsets and uses the %pf
instead.

 %pF produces run_local_timers+0x4/0x1f
 %pf produces just run_local_timers

For PowerPC64, we need to use the direct pointer, and we only have
%pS which will produce .run_local_timers+0x4/0x1f

This patch creates a %ps that matches the %pf as %pS matches %pF.
