We are working on supporting the AR9003 chipset family.
This is the new 802.11n family of chipset by Atheros,
it will include 2-stream chipsets and the new shiny 3-stream
chipsets. The plan of attack is to support the 2-stream
chipsets first and then move on the the 3-stream devices.
The new family of chipsets are supported in the same traditional
Atheros way of using code on the host, however the register map
for the new chipset is now defined through an alternative approach [1].
This essentially requires new routines for every read/write operation
and as such requires an abstraction layer for hardware support.
This first patch series illustrates the direction I'm taking so far
for the abstraction. Please review and let me know what you think.
Fortunately I believe we will be able to re-use some core harware
code by implementing both generic harware callbacks and also some
private callbacks, to be used only by hardware code itself. I
intend on stuffing the generic harware code on hw.c and moving
chipset specific stuff into their own files.
Let me know what you think so far. If this seems peachy I'll
continue with this strategy and complete the abstraction for
the AR5008/AR9001/AR9002 family first. We can then work on
the AR9003 family support by simply adding new callbacks for
it.
There are some cases where I think its pointless to keep using
callbacks where the code is exactly the same and although we are
using a different register definition for some families they are
ikely 100% identical. A case I found so far was ath9k_hw_chip_test()
and in fact I noticed we can even share this same call with
the legacy family, through ath5k. So I think in cases like those
where not many registers are being picked at it makes sense to
standardize the calls accross the board, and sometimes this may
mean sharing for all the chipset families, legacy, and all 802.11n
including the new ar9003 family.

ath9k supports the AR5008, AR9001 and AR9002 family of Atheros
chipsets, all 802.11n. The new breed of 802.11n chips, the
AR9003 family will be supported as well but each register read
and write uses a different register definition and and such
to support it we need to build a hardware family abstraction
layer.
This patch starts the abstraction layer through a set of callbacks.
Our approach is to avoid as much duplicate code as is possible so
where we can we will be re-using the same routines and only add
callbacks for specific hardware functions which do direct hardware
reads or writes. This starts off addressing hardware routines used
during hardware initialization.

* [ath9k-devel] [RFC 1/3] ath9k: start building an abstraction layer for hardware routines
@ 2010-03-05 3:44 ` Luis R. Rodriguez
0 siblings, 0 replies; 14+ messages in thread
From: Luis R. Rodriguez @ 2010-03-05 3:44 UTC (permalink / raw)
To: ath9k-devel
ath9k supports the AR5008, AR9001 and AR9002 family of Atheros
chipsets, all 802.11n. The new breed of 802.11n chips, the
AR9003 family will be supported as well but each register read
and write uses a different register definition and and such
to support it we need to build a hardware family abstraction
layer.
This patch starts the abstraction layer through a set of callbacks.
Our approach is to avoid as much duplicate code as is possible so
where we can we will be re-using the same routines and only add
callbacks for specific hardware functions which do direct hardware
reads or writes. This starts off addressing hardware routines used
during hardware initialization.

To: linux-wireless, ath9k-devel
Cc: kevin, doug.dahlby, cliff.holden, Luis R. Rodriguez
Move wardware code specific to ar9002 to its own file to make
things easier to read and manage. This just shuffles code and
adds three private hardware callbacks to allow us to move the
rest: init_pll, init_mode_gains and init_14_spread.

And yes, I do have:

on my .gitconfig -and I did use -M here for format-patch, but
since its not a rename it obviously won't reat it as such.

* [ath9k-devel] [RFC 2/3] ath9k: initial move of ar9002 specific code to its own file
@ 2010-03-05 3:44 ` Luis R. Rodriguez
0 siblings, 0 replies; 14+ messages in thread
From: Luis R. Rodriguez @ 2010-03-05 3:44 UTC (permalink / raw)
To: ath9k-devel
Move wardware code specific to ar9002 to its own file to make
things easier to read and manage. This just shuffles code and
adds three private hardware callbacks to allow us to move the
rest: init_pll, init_mode_gains and init_14_spread.

since its not a rename it obviously won't reat it as such.

The register initialization values we have so far are
only for the AR5008, AR9002 and AR9002 hardware families
and we've managed to get ar90002_hw.c to be its only user
so clarify this by renaming the initvals.

I also forgot to mention that I see two advantages with this new
approach. With this abstraction in place if we really wanted to we
could try to unify ath5k/ath9k some more, although it is not one of my
own goals. Another neat advantage we can take from the new changes is
add a tracer on hw-ops.h.

Should this possibly be ar9002_initvals.h as to match up with ar9002_hw.c?
