Dear coreboot folks,
just a note to inform you, that Andy Lutomirski sent some MTRR patches
to the Linux kernel lists [1] with the following cover letter.
[PATCH 0/7] Clean up write-combining MTRR addition
A fair number of drivers (mostly graphics) add write-combining MTRRs.
Most ignore errors and most add the MTRR even on PAT systems which don't
need to use MTRRs.
This series adds new functions mtrr_{add,del}_wc_if_needed and
drm_mtrr_{add,del}_wc that report errors and do nothing if PAT is
enabled.
I've only tested the radeon driver, since I don't have test hardware
easily available for the other drivers.
Benefits include:
- Simpler code
- No more complaints about MTRR conflict warnings on PAT systems
- Eventual unexporting of the MTRR API?
This series eliminates about half of the mtrr_add calls in drivers/.
The series is also at:
https://git.kernel.org/cgit/linux/kernel/git/luto/linux.git/log/?h=mtrr_cle…
Andy Lutomirski (7):
x86: Add mtrr_{add,del}_wc_if_needed
drm (ast,cirrus,mgag200,nouveau,savage,vmwgfx): Rework drm_mtrr_{add,del}
drm: Update drm_addmap and drm_mmap to use PAT WC instead of MTRRs
drm: Use drm_mtrr_add_wc for the AGP aperture
i915: Use drm_mtrr_{add,del}_wc
radeon: Switch to drm_mtrr_add_wc and add a missing drm_mtrr_del_wc
uvesafb: Clean up MTRR code
I have not looked at them, but maybe some of the ideas can be used for
coreboot too.
Thanks,
Paul

AFAIK, patches for gcc has been included,
seems a patch for binutil is required,

BTW, I have to build mipsel-elf by hand for poor-internet-access-speed.

It is safe to assume that the answer is always 'no'.
If you want the code, you have to write it.

Are there any plans to support the ASUS A8AE-LE (Amberine M)? According to
HP, this board (Socket 939) has an ATI RS480 NB, ATI SB400 SB, and an Asus
A8000 Super I/O.

Asrock E350M1 (using Agesa)
CPU0: stack: 002b0000 - 002c0000, lowest used address 002bf75c, stack used: 2212 bytes
CPU1: stack: 002a0000 - 002b0000, lowest used address 002afda8, stack used: 600 bytes
So it would work just fine with the default 4K stack size, even if it
took almost twice of the above measurement due to more complex hardware
in the system (extremely unlikely)
Boards with custom stack size:
* asrock/e350m1
* asus/f2a85-m
* technexion/tim5690
* msi/ms9652_fam10
* tyan/s8226
* supermicro/h8scm
* supermicro/h8qgi
* supermicro/h8qme_fam10
* amd/inagua
* amd/parmer
* amd/south_station
* amd/thatcher
* amd/dinar
* amd/torpedo
* amd/persimmon
* amd/union_station

Other than for wakeup-from-suspend, no-one ever cares if that's 4k or
400k, except that things might fail if it is too small.
And Google is the first organisation with a huge interest in an
optimized wakeup in coreboot.

One of the majore things needed on the BSP used to be lzma decompression
which put a 16K array on the stack. We fixed this a while ago, bringing
down stack usage on our Intel based boards to about 1K (and giving each
core a 4K stack)
We fixed the issue by putting that big array in the heap instead. Maybe
we can fix the AMD code in the same way.
I would like to see some actual stack usage data first though
