[ALSA] snd-hda-intel: use WALLCLK register to check for early irqs

Use 24Mhz WALLCLK register to ignore too early interrupts and
wrong interrupt status. The bad timing confuses the higher ALSA
layer and causes audio skipping. More information about behaviour
and debugging can be found in kernel bz#15912.

Shahin Ghazinouri [Tue, 11 May 2010 06:19:55 +0000]
ALSA: hda - Fixes distorted recording on US15W chipset

The HDA controller in US15W (Poulsbo) reports inaccurate position values
for capture streams when using the LPIB read method, resulting in
distorted recordings.

However, using the position buffer is broken for playback streams,
resulting in a fallback to the LPIB method with the current driver.
This patch works around the issue by independently detecting the read
position method for capture and playback streams.

The patch will not have any effect if the position fix method is
explicitly set.

Takashi Iwai [Mon, 29 Mar 2010 15:21:45 +0000]
ALSA: hda - Fix ADC/MUX assignment of ALC269 codec

ALC269 codec has a few different variants, and each of them may have
different ADC and MUX widgets.  For example, one model has ADC 0x08
with MUX 0x23 while others has ADC 0x09 or ADC 0x07 with MUX 022 or
0x24.  The difference of ADC appears usually as the capability of
the digital mic pin (0x12), and the current driver sometimes misses
the internal mic pin due to the mismatching ADC.

This patch adds a bit more clever way to find the matching ADC instead
of the static list.  Now the driver checks all active input pins and
fills only the ADC/MUX's that contain all of them.

Anton Blanchard [Mon, 22 Mar 2010 06:47:59 +0000]
ppc64 sys_ipc breakage in 2.6.34-rc2

I chased down a fail on ppc64 on 2.6.34-rc2 where an application that
uses shared memory was getting a SEGV.

Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 ("Add generic sys_ipc
wrapper") changed the second argument from an unsigned long to an int.
When we call shmget the system call wrappers for sys_ipc will sign
extend second (ie the size) which truncates it.  It took a while to
track down because the call succeeds and strace shows the untruncated
size :)

The patch below changes second from an int to an unsigned long which
fixes shmget on ppc64 (and I assume s390, sparc64 and mips64).

I assume the function prototypes for the other IPC methods would cause us
to sign or zero extend second where appropriate (avoiding any security

9 years agoipv4: Don't drop redirected route cache entry unless PTMU actually expired
Guenter Roeck [Mon, 22 Mar 2010 03:55:13 +0000]
ipv4: Don't drop redirected route cache entry unless PTMU actually expired

TCP sessions over IPv4 can get stuck if routers between endpoints
do not fragment packets but implement PMTU instead, and we are using
those routers because of an ICMP redirect.

Setup is as follows

       MTU1    MTU2   MTU1
    A--------B------C------D

with MTU1 > MTU2. A and D are endpoints, B and C are routers. B and C
implement PMTU and drop packets larger than MTU2 (for example because
DF is set on all packets). TCP sessions are initiated between A and D.
There is packet loss between A and D, causing frequent TCP
retransmits.

After the number of retransmits on a TCP session reaches tcp_retries1,
tcp calls dst_negative_advice() prior to each retransmit. This results
in route cache entries for the peer to be deleted in
ipv4_negative_advice() if the Path MTU is set.

If the outstanding data on an affected TCP session is larger than
MTU2, packets sent from the endpoints will be dropped by B or C, and
ICMP NEEDFRAG will be returned. A and D receive NEEDFRAG messages and
update PMTU.

Before the next retransmit, tcp will again call dst_negative_advice(),
causing the route cache entry (with correct PMTU) to be deleted. The
retransmitted packet will be larger than MTU2, causing it to be
dropped again.

This sequence repeats until the TCP session aborts or is terminated.

Problem is fixed by removing redirected route cache entries in
ipv4_negative_advice() only if the PMTU is expired.

NET_DMA: free skbs periodically

Under NET_DMA, data transfer can grind to a halt when userland issues a
large read on a socket with a high RCVLOWAT (i.e., 512 KB for both).
This appears to be because the NET_DMA design queues up lots of memcpy
operations, but doesn't issue or wait for them (and thus free the
associated skbs) until it is time for tcp_recvmesg() to return.
The socket hangs when its TCP window goes to zero before enough data is
available to satisfy the read.

Periodically issue asynchronous memcpy operations, and free skbs for ones
that have completed, to prevent sockets from going into zero-window mode.

ixgbevf: Fix VF Stats accounting after reset

The counters in the 82599 Virtual Function are not clear on read.  They
accumulate to the maximum value and then roll over.  They are also not
cleared when the VF executes a soft reset, so it is possible they are
non-zero when the driver loads and starts.  This has all been accounted
for in the code that keeps the stats up to date but there is one case
that is not.  When the PF driver is reset the counters in the VF are
all reset to zero.  This adds an additional accounting overhead into
the VF driver when the PF is reset under its feet.  This patch adds
additional counters that are used by the VF driver to accumulate and
save stats after a PF reset has been detected.  Prior to this patch
displaying the stats in the VF after the PF has reset would show
bogus data.
