Toggle the interface on and off before starting the diag test. This
seems to be necessary for the 8139C+ under certain circumstances, and
doesn't appear to hurt the other chips. (In the failure case, the
packet would be sent through the TX DMA ring but not get echoed
back. I suspect this has something to do with the link state changing
unexpectedly.)
- For the 8169 chips, read the station address by forcing an EEPROM
autoload and then copying the contends of the station address
registers. For some reason, reading the EEPROM on the 8169S doesn't
work right. This gets around the problem, and allows us to read
the station address correctly on the 8169S.
- Insert a delay after initiating packet transmition in re_diag() to
allow lots of time for the frame to echo back to the host, and wait
for both the 'RX complete' and 'timeout expired' bits in the ISR
register to be set.
- Deal more intelligently with the fact that the frame length
field in the RX descriptor is a different width on the 8139C+
than it is on the 8169/8169S/8110S
- For the 8169, you have to set bit 17 in the TX config register
to enter digital loopback mode, but for the 8139C+, you have to
set both bits 17 and 18. Take this into account so that re_diag()
works properly for both types of chips.
Add a PHY driver to support the built-in gigE PHY in the 8169S/8110S
ethernet chips. This driver is pretty simple, however it contains
special DSP initialization code which is needed in order to get
the chip to negotiate a gigE link. (This special initialization
may not be needed in subsequent chip revs.) Also:
- Fix typo in if_rlreg.h (RL_GMEDIASTAT_1000MPS -> RL_GMEDIASTAT_1000MBPS)
- Deal with shared interrupts in re_intr(): if interface isn't up,
return.
- Fix another bug in re_gmii_writereg() (properly apply data field mask)
- Allow PHY driver to read the RL_GMEDIASTAT register via the
re_gmii_readreg() register (this is register needed to determine
real time link/media status).
Rewrite the SAPIC initialization to always program the RTEs with what
we think is the correct trigger mode and polarity. This allows us to
implement BUS_CONFIG_INTR() as an update of the RTE in question.
Consequently, we can trust the RTE when we enable an interrupt and
avoids that we need to know about the trigger mode and polarity at
that time.
Extend the ACPI resource handling to make use of the BUS_CONFIG_INTR()
method. This is necessary on ia64 where it's known that serial interfaces
described in the ACPI namespace may not have the well-known IRQs assigned
to them. This confuses us in thinking they are PCI based interrupts and
wrongly program the APIC.
o Workaround a bug where my T23 reports that it is ACPI 2.0x compatible
but has invalid 64 bit pointers for FACS and DSDT.
o Finish work to print all of the FADT and FACS.
o Resort the comment generating functions. Submitted by: marcel
Introduce BUS_CONFIG_INTR(). The method allows devices to tell parents
about interrupt trigger mode and interrupt polarity. This allows ACPI
for example to pass interrupt resource information up the hierarchy.
The default implementation of the method therefore is to pass the
request to the parent.
- Add 'enable_exim="YES"' to rc.conf(5)
- Use the default exim configuration file from the port
- When using sendmail, disable some more scripts that use sendmail specific
parameters
- Have sysinstall tweak mailer.conf(5) substitution
- Use 'N' flag for newsyslog(8)

Update hardware revision table. 0x04000000 appears to be the revision
for the 8169S, according to my sample board. The RealTek Linux driver
mentions 0x00800000. I'm assigning this to the 8110S until I get
more info on it. (The (preliminary) RealTek docs only say that 8169S/8110S
chips will have some combination of those two bits set, but doesn't say
exactly what bit combination goes with which chip variant.)
We represent PCI intpin's two different ways. One is the way that the
intpin register is expressed in hardware where 0 means none, 1 means INTA,
2 INTB, etc. The other way is commonly used in loops where 0 means INTA,
1 means INTB, etc. The matchpin argument to pci_cfgintr_search() is
supposed to be the first form, but we passsed in a loop index of the
second. This fix adds one to the loop index to convert to the first form.
If we failed to size the Rx FIFO, assume the worst. This however
is not a size of 1. Since we already know there is a FIFO, we can
safely assume that it is at least 16 bytes. Note that all this is
mostly academic anyway. We don't use the size of the Rx FIFO
currently. If we add support for hardware flow control, we only
care about Rx FIFO sizes larger than 16.
Original pthread_once code has memory leak if pthread_once_t is used in
a shared library or any other dyanmic allocated data block, once
pthread_once_t is initialized, a mutex is allocated, if we unload the
shared library or free those data block, then there is no way to deallocate
the mutex, result is memory leak.
To fix this problem, we don't use mutex field in pthread_once_t, instead,
we use its state field and an internal mutex and conditional variable in
libkse to do any synchronization, we introduce a third state IN_PROGRESS to
wait if another thread is already in invoking init_routine().
Also while I am here, make pthread_once() conformed to pthread cancellation
point specification.
Switch dotrim() to take advantage of the 'struct conf_entry' that
is already passed in, instead of having the caller copy values from
that struct into additional parameters.

Clean up get/set_mcontext() and get/set_fpcontext(). These are operated
on data structures on the kernel stack which are guaranteed to be 16 byte
aligned by gcc, the amd64 ABI and __aligned(16).
Ensire the tss_rsp0 initial stack pointer is 16 byte aligned in case
sizeof(pcb) becomes odd at some point. This is convenient for the
interrupt handler case because the ring crossing pushes cause the
required odd alignment before the call to the C code.
Have fast_syscall add an additional 8 bytes to ensure that the trapframe
has the correct odd alignment for the call to C code. Note that there are
no checks to make sure that the trapframe size is appropriate for this.
This makes get/setfpcontext work properly (finally). You get a GPF in
kernel mode if any of this is botched without the alignment fixup code
that is apparently needed on i386.
Add a device driver for the Broadcom BCM4401 ethernet controller,
written by Stuart Walsh and Duncan Barclay (with some kibbitzing by
me). I'm checking it in on Stuart's behalf.
The BCM4401 is built into several x86 laptop and desktop systems. For the
moment, I have only enabled it in the x86 kernel config because although
it's a PCI device, I haven't heard of any standalone NICs that use it. If
somebody knows of one, we can easily add it to the other arches.
This driver uses register/structure data gleaned from the Linux
driver released by Broadcom, but does not contain any of the code
from the Linux driver itself. It uses busdma.
Rename FACP to FADT throughout.
Update FADT for new fields including pm_profile, pstate_cnt, and cst_cnt.
Add acpi_print_gas() for printing various address formats.
Print FACS contents.
Remove unused code.
Introduce IA64_ID_PAGE_{MASK|SHIFT|SIZE} and LOG2_ID_PAGE_SIZE. The
latter is a kernel option for IA64_ID_PAGE_SHIFT, which in turn
determines IA64_ID_PAGE_MASK and IA64_ID_PAGE_SIZE.
The constants are used instead of the literal hardcoding (in its
various forms) of the size of the direct mappings created in region
6 and 7. The default and probably only workable size is still 256M,
but for kicks we use 128M for LINT.
Add a '-D <something>' command line arg, which can be used to set
debugging options. Initial option is '-D TN=<time>', which can be
used to see how newsyslog would work if run at the specified time.
(time format is ISO 8601, since that is already supported).
Disallow attempts to suspend to S0. It was only enabled for testing.
Print a more informative message if a sleep state is not supported by BIOS.
Add comments.
Quiet down boot verbose and allow commands to be submitted to a target
which does not have a volume attached. This will stop cam from retrying
a bunch of time at boot for devices which do not exsist.
In the !MNT_BYFSID case, return EINVAL from unmount(2) when the
specified directory is not found in the mount list. Before the
MNT_BYFSID changes, unmount(2) used to return ENOENT for a nonexistent
path and EINVAL for a non-mountpoint, but we can no longer distinguish
between these cases. Of the two error codes, EINVAL was more likely
to occur in practice, and it was the only one of the two that was
documented.
Update the manual page to match the current behaviour.
