64dc1cf395 Implement MSI support.
MSI are implemented via Inbound Shared Doorbell 1 interrupts. Interrupts
are triggered by writing to Software Triggered Interrupt registeri (PCIe
card using physical address of this register in BAR0 space). There are 32
interrupts available. It can be increased by using Doorbell 2 and
Doorbell 3 registers to 96 interrupts.

MSI are implemented via software interrupt. PCIe cards will write
into software interrupt register which will cause inbound shared
interrupt which will be interpreted as a MSI.

9b967f5d12 Don't use AR_PHY_MODE to setup half/quarter rate.
I'm not sure where in the deep, distant past I found the AR_PHY_MODE
registers for half/quarter rate mode, but unfortunately that doesn't
seem to work "right" for non-AR9280 chips.

Specifically:

* don't touch AR_PHY_MODE
* set the PLL bits when configuring half/quarter rate

I've verified this on the AR9280 (5ghz fast clock) and the AR5416.

The AR9280 works in both half/quarter rate; the AR5416 unfortunately
only currently works at half rate.  It fails to calibrate on quarter rate.

9215d178a4 Introduce a new make variable COMPILER_TYPE that specifies what
type of compiler is being used (currently clang or gcc).  COMPILER_TYPE
is set in the new bsd.compiler.mk file based on the value of the CC
variable or, should it prove informative, by running ${CC} --version
and examining the output.

To avoid negative performance impacts in the default case and correct
value for COMPILER_TYPE type is determined and passed in the environment
of submake instances while building world.

Replace adhoc attempts at determining the compiler type by examining
CC or MK_CLANG_IS_CC with checks of COMPILER_TYPE.  This eliminates
bootstrapping complications when first setting WITH_CLANG_IS_CC.

df3cbc41fa The deadfs VOPs for vop_ioctl and vop_bmap call itself recursively,
which is an elaborate way to cause kernel panic. Change the VOPs
implementation to return EBADF for a reclaimed vnode.

While the calls to vop_bmap should not reach deadfs, it is indeed
possible for vop_ioctl, because the VOP locking protocol is to pass
the vnode to VOP unlocked. The actual panic was observed when ioctl
was called on procfs filedescriptor which pointed to an exited
process.

5b5d76847d Rename __member2struct() to __containerof().
Compared to __member2struct(), this macro has the following advantages:

- It ensures that the type of the pointer is compatible with the member
  field of the structure (or a void pointer).
- It works properly in combination with volatile and const, though
  unfortunately it drops these qualifiers from the returned value.

mdf@ proposed to add the container_of() macro, just like Linux has.
Eventually I decided against this, as <sys/param.h> is included all over
the place. It seems container_of() on Linux is specific to the kernel,
not userspace. I'd rather not pollute userspace with this.

I also thought about adding __container_of(), but this would have two
advantages. Xorg seems to already have a __container_of(), which is not
compatible with this version. Also, the underscore in the middle
conflicts with our existing macros (__offsetof, __rangeof, etc).

I'm changing member2struct() to use its old code, as the extra
strictness of this new macro conflicts with existing code (read: cxgb).

77ffc4c1fc Flip on half/quarter rate support.
No, this isn't HT/5 and HT/10 support.  This is the 11a half/quarter
rate support primarily used by the 4.9GHz and GSM band regulatory
domains.

This is definitely a work in progress.

TODO:

* everything in the last commit;
* lots more interoperability testing with the AR5212 half/quarter rate
  support for the relevant chips;
* Do some interop testing on half/quarter rate support between _all_
  the 11n chips - AR5416, AR9160, AR9280 (and AR9285/AR9287 when 2GHz
  half/quarter rate support is coded up.)

ce801478d2 Introduce an AR5416 flavour of the IFS and mac usec/timing configuration
used when running the chips in half/quarter rate.

This sets up some default parameters which are then overridden by the
driver (which manually configures things like slot timing at interface
start time.)

Although this is a copy-and-modify from the AR5212 HAL, I did peek
at the reference HAL and the ath9k driver to see what they did.
Ath9k in particular doesn't hard-code this - instead, their version
of ar5416InitUserSettings() does all of the relevant math.

TODO:

* do the math, not hard code things!
* fix the mac clock calculation for the AR9287; since it runs the
  MAC clock at a higher rate, requiring all the duration calculations
  to change;
* Do a whole lot more validation for half/quarter rates.

41b53a9aaf Call the ar5212SetCoverageClass() function for now.
Some of the math is a little wrong thanks to clocks in 11a mode running
at 44MHz when in fast clock mode (rather than 40MHz, which the chips
before AR9280 ran 11a in).  That'll have to be addressed in a future commit.

e48063402c Correctness: use __member2struct() on the correct fields.
The prev-pointers point to the next-pointers of the previous element --
not the ENTRY structure. The next-pointers are stored in the ENTRY
structures first, so the code would already work correctly. Still, it is
more accurate to use the next-fields.

To prevent misuse of __member2struct() in the future, I've got a patch
that requires the pointer to be passed to this macro to be compatible
with the member of the structure. I'll commit this patch after I've
tested it properly.

4170b08388 Implement LIST_PREV().
Regular LISTs have been implemented in such a way that the prev-pointer
does not point to the previous element, but to the next-pointer stored
in the previous element. This is done to simplify LIST_REMOVE(). This
macro can be implemented without knowing the address of the list head.

Unfortunately this makes it harder to implement LIST_PREV(), which is
why this macro was never here. Still, it is possible to implement this
macro. If the prev-pointer points to the list head, we return NULL.
Otherwise we simply subtract the offset of the prev-pointer within the
structure.

It's not as efficient as traversing forward of course, but in practice
it shouldn't be that bad. In almost all use cases, people will want to
compare the value returned by LIST_PREV() against NULL, so an optimizing
compiler will not emit code that does more branching than TAILQs.

While there, make the code a bit more readable by introducing
__member2struct(). This makes STAILQ_LAST() far more readable.
