secondary bus is 0, we program the primary bus, the secondary bus and
the suborindate bus. This isn't ideal, since we start at parent_bus +
1 and store this in a static.
Ideally, we'd walk the tree and assign bus numbers. However, that's
harder to accomplish without some help from the bus layer which we're
not planning on doing that until 6.
This fixes my CardBus problems on my Sony PCG-Z1WA, and might fix the
Dells that have had problems.
sched_ule, in January 2004. Looking at this, "pagezero" is (one of) the
culprit(s). We had no provision for processes with P_NOLOAD set. With
pagezero not running at PRI_ITHD, kseq_load_{add,rem} count pagezero as
another-normal-process, thus the "expected-plus-one" load reported in
the above thread.

gadgets (hotkeys, lcd, ...) on Asus laptops. I aim to closely track the
acpi4asus project which implements these features in the Linux kernel.
If this breaks your laptop, please let me know how it does it :-)

there are a lot of other dependencies that preclude the kernel from
working). Instead, have a more generic note that isa should not be
removed. This should be less confusing for users.

This fixes problems that occurred when using positional arguments in
format strings, particularly with more than STATIC_ARG_TBL_SIZE (8)
of them.

My original instinct to make ndis_return_packet() asynchronous was correct.
Making ndis_rxeof() submit packets to the stack asynchronously fixes
one recursive spinlock acquisition, but it's also possible for it to
happen via the ndis_txeof() path too. So:
- In if_ndis.c, revert ndis_rxeof() to its old behavior (and don't bother
putting ndis_rxeof_serial() back since we don't need it anymore).
- In kern_ndis.c, make ndis_return_packet() submit the call to the
MiniportReturnPacket() function to the "ndis swi" thread so that
it always happens in another context no matter who calls it.
workaround was for hardware where the clock was not latched, not for
hardware that was too slow. Also, make variable names more specific for ddb
printing.
adjunct maps are used. One symtom of this bug is sshd saying:
login_get_lastlog: Cannot find account for uid X
when logging in. The problem here is caused by an incorrect reuse of the rv
variable when previous values are needed later.
While I would have prefered to have a solution that didn't move
knowledge of this into the pci layer. However, this is literally the
only exception that's listed in the PCI standard to the usual way of
decoding BARs. atapci devices in legacy mode now ignore the first 4
bars and hard code the values to the legacy ide values (well, for each
of the controllers that are in legacy mode). The 5th bar is handled
normally.
Remove the zero bar handling. zero bars should be ignored at all
other times, and since we handle that specially, we don't need the
older workaround.
what the ACPI-safe workaround is intended to fix. Requested by phk.
Set the bushandle and tag when attaching the timer, don't do it each time
in read_counter(). Pointed out by bde.
Move test_counter() to the end. Staticize acpi_timer_reg.
Clearly comment the assumptions on the structure of keys (addresses)
and masks, and introduce a macro, LEN(p), to extract the size of these
objects instead of using *(u_char *)p which might be confusing.
Comment the confusion in the types used to pass around pointers
to keys and masks, as a reminder to fix that at some point.
Add a few comments on what some functions do.
Comment a probably inefficient (but still correct) section of code
in rn_walktree_from()
The object code generated after this commit is the same as before.
At some point we should also change same variable identifiers such
as "t, tt, ttt" to fancier names such as "root, left, right" (just
in case someone wants to understand the code!), replace misspelling
of NULL as 0, remove 'register' declarations that make little sense
these days.
High-resolution mtime/ctime/atime is not POSIX-standard, so hide
set/get of high-resolution time fields behind easily-mutable macros.
That makes it easier to change how those fields are accessed.
like "the foo(4) manual page" to "foo(4)". Uniformized the remaining
instances of "manual page" and "manpage" to "man page". Uniformized
some nearby sentence breaks. Reformatted the whole paragraph containing
these changes only for DUMMYNET.
of you with other cards, please do review and test the drivers for
MP-safety and disable Giant in the interrupt routines when you are
sure of proper functionality.
