reasons. RH0 was already removed in the kernel's input path, but some
parts were still present in the output path: they are now removed.

when all descriptors in a queue are free. When all descriptors are free after
wm_txeof(), it's caused by lost interrupt (though I've never seen it). One
possibility is chip bug and another possibility is software bug. We should
reset in any cases. If we don't reset and don't print error message, TX
processing is done intermittently and user might not noticed the problem.
- Rename txq_watchdog to txq_sending to make the meaning clear.
leading whitespace in the value of var (because strtoimax() does)
but did not allow trailing whitespace. The effect is that some
cases where $(( ${var:-0} )) would work do not work without the $
expansion.
Fix that - allow trailing whitespace. However, continue to insist
upon at least one digit (a non-null var that contains nothing but
whitespace is still an error).
Note: posix is not helpful here, it simply requires that the variable
contain "a value that forms a valid integer constant" (with an optional
+ or - sign).
Don't synerr on
${var-anything
more}
The newline in the middle of the var expansion is permitted.
Bug reported by Martijn Dekker from his modernish tests.
XXX pullup-8
Currently this test case will fail, a fix is coming soon (not worth
marking this as an expected failure.)
This test case and the initial bug report comes from
Martijn Dekker's modernish (shell/test set).
value is written leaving the autoconf setting (-1) as the address.
The value is only used for printing an attach message, the actual
pcdisplay_init code uses hard coded base addresses again.
The check enforces a 4-byte-aligned size for the option mbuf. If the size
is not multiple of 4, the computation of ip_hl gets truncated in the
output path. There is no reason for this check not to be present on VAX.
While here add a KASSERT in ip_insertoptions to enforce the assumption.
Discussed briefly on tech-net@
- get rid of the special smuiicbus, use generic i2cbus
- use shifted i2c addresses like everyone else
- use direct config
with this generic i2c drivers should work on the smu's i2c bus.
at this time I'm not sure what draining the fifo means here. Also,
we're not waiting for the drain to complete.
The upper level will play enough silence when needed to make sure interesting
data have been played.
In sunxi_codec_halt_output() and sunxi_codec_halt_input(), drain the fifo
(and wait for it to complete) before or after disabling the DMA.
the LOAD bit. This is how it was done in the allwinner code.
I don't know why but without this, I could play sound (via sunxi_codec)
only once. After the call to sunxi_codec_halt_output(), subsequent play
would output only silence.
This is done by having a secondary timer against rainfo so we
can delay unicasting by the required randomised amount of time
without affecting the unsolicited RA timer.
readhappy_mpsafe - demonstrates how to make a module MPSAFE
This module contains an additional helper program test_readhappy.c,
that is designed to exercise the kernel module with multiple threads.
