b010577828 I've had verification that the second-last 64k is actually used by the tplink
firmware to store configuration data.

It's safe to overwrite it.
2011-11-24 15:12:57 +00:00
Adrian Chadd
019d307f35 Now that I've brought up FreeBSD via flash, I've discovered that
the second-last 64k seems to be the default firmware board configuration
area.

Since I have no idea whether uboot uses it or not - and it's prefixed
with an atheros eeprom signature (0xaa55), I figure the safest thing
to do is mark it as read-only.

I've modified my local tplink firmware building program to generate
a board configuration section - which is separate to this partition.
It's located in the 64k _before_ this particular 64k.

The firmware build program from OpenWRT never initialises those
values and the firmware images from tplink also leave it 0x0, so I
don't currently know what the exact, correct details should be.

b1214c6893 Flip on AR71XX_ENV_UBOOT so the environment variables are properly
processed. (Which is to say they're currently ignored.)
2011-11-24 07:33:41 +00:00
Adrian Chadd
1c3ed0a410 Introduce a new (global, sorry!) option which controls whether
the ar71xx platform code should assume a uboot or redboot environment.

The current code gets very confused (and just crashes) on a uboot
environment, where each attribute=value pair is in a single entry.
Redboot on the other hand stores it as "attribute", "value", "attribute",
"value", ...

This allows the kernel to boot on a TP-LINK TL-WR1043ND from flash,
where the uboot environment gets setup. This didn't show up during a netboot
as "tftpboot" and "go" don't setup the uboot environment variables.

35d1603e8a Flesh out a geom_map setup, so the kernel can be squeezed _onto_ the device.
The default flash layout gives only 1 megabyte for the kernel, gzipped.
The uboot firmware running on this device only supports gzip, not lzma, so
we actually _do_ have to try and slim the kernel down a bit.

But, since I can't actually do that at the present, I'm opting to:

* extend the kernel from 1mb to 2mb;
* have rootfs fill the rest of that, save 64k;
* eventually I'll hide a 64k config partition at the end, between the
  end of rootfs and the ART (radio configuration data.)

The uboot firmware doesn't care about the partition layout. It just
expects the kernel application image to sit at 0xbf020000 (right after
the 128k uboot image.) The uboot header isn't actually read either -
it's "faked" from a "tplink" flash image header. So as long as the
map configuration here matches what is being written out via the
tplink firmware generator, everything is a-ok.

5c85f74c64 Compile in the right bits so the AR9130 WMAC support functions correctly.
A previous commit disabled compiling the AR9130 support in the default
HAL build in the kernel. Since the AR9130 support won't actually function
without AH_SUPPORT_AR9130 (and that abomination needs to be undone at some
point, in order to allow USB 11n NICs to also work), we now have to
explicitly compile it in.

But since the 11n RF backends don't (currently) join the RF linker set,
one has to compile in _an_ RF backend for the HAL to compile.

68d31a0864 Add a comment documenting where the WMAC hangs off of.
At some point it would be nice to correctly update the bus glue to make

4b7ec27007 - There's no need to overwrite the default device method with the default
one. Interestingly, these are actually the default for quite some time
  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)
  since r52045) but even recently added device drivers do this unnecessarily.

cca2c4b446 Do pmap update only on active CPUs.
The pmap update_page/invalidate_page/invalidate_all operations has to be
done only on active cpus. In the simplest case, if the process is not
active on any other CPUs, we can just do the operation on the current CPU.

This change replaces the call to smp_rendezvous() for these operations with
smp_rendezvous_cpus() in case there more than one active CPU, or with a direct
function call if there is just one active CPU.

This change give significant performance increase in fork/exec benchmarks
on XLR/XLS/XLP with 32 cpus.

a50079b7ff People porting FreeBSD to new architectures ought not have to
implement a deprecated FPU control interface in addition to the
standard one.  To make this clearer, further deprecate ieeefp.h
by not declaring the function prototypes except on architectures
that implement them already.

Currently i386 and amd64 implement the ieeefp.h interface for
compatibility, and for fp[gs]etprec(), which doesn't exist on
most other hardware.  Powerpc, sparc64, and ia64 partially implement
it and probably shouldn't, and other architectures don't implement it
at all.

29550c285c Fix wakeup latency when sleeping with 'wait'
If we handle an interrupt just before the 'wait' and the interrupt
schedules some work, we need to skip the 'wait' call. The simple solution
of calling sched_runnable() with interrupts disabled immediately before
wait still leaves a window after the call and before 'wait' in which
the same issue can occur.

The solution implemented is to check the EPC in the interrupt handler, and
if it is in a region before the 'wait' call, to fix up the EPC to skip the
wait call.
