I've read posts about the RD1 that suggest its integrated flash device
is low quality and it may take 10 or more flash attempts to get a good
flash update to the RD1 flash device.
As a result, many RD1 BIOS Savior users will flash the commercial
BIOS image (or other known good BIOS image) into the RD1 integrated
flash device as many times as needed to get an image that boots.
Then use the original BIOS device to flash test BIOS image (usually
LinuxBIOS images among this group), since the original BIOS device
usually flashes OK on the first attempt.
I've used the RD1 in the above fashion with great success on the
Tyan S2885 mainboard.
The same RD1 would not work on the nVidia CK8-04 CRB mainboard.
I think the CK8-04 CRB requires a flash device that the RD1 does
not support. However, the RD1 worked well as an "do nothing" adapter
which allowed swapping the BIOS flash device between my flash burner
and the mainboard without any wear to the mainboard's BIOS socket.
BTW, my flash burner is an older Enhanced Willem Universal Programmer.
I got mine for only $60 US over a year ago. I've seen it for less
than $40 on eBay a few weeks ago. The newest model is going for about
$50 US. It does a LinuxBIOS flash in about 5 minutes; not bad for a
$60 burner. However, it does require changing DIP switches to match
an image for each device it can program. Great for the amateur or
professional with a small budget.

Mine cable and switch worked fine out of the box as well.

andi,
I tried to lift apic id in LinuxBIOS for all cpus after 0x10.
When using MB with AMD8111, the jiffies was not moving. So it is
locked at calibrate_delay_direct...
but MB with Nvidia ck804, jiffies is moving.
If I don't change BSP apic id ( keep it to 0), It changes....
I have no idea how the jiffies changes, there is another thread change it....?

Subject: [LinuxBIOS] E7501 Raminit rewrite
This one ends up being a little more than a "patch".
I ended up reorganizing the E7501 raminit code so I could follow it, and
fixed some bugs along the way.
Significant logical changes:
* Added support for "fast" (64-clock) refresh
* Added code to support remap window for 3 - 4 GB systems
* Fixed premature configuration of true row boundaries that resulted in
some sections of DRAM not receiving JEDEC commands (see
http://openbios.org/pipermail/linuxbios/2005-June/011752.html).
* Redefined RCOMP_MMIO so that RCOMP registers can be configured on
systems where A20M# is asserted.
* Disabled subsystem (vendor) ID configuration
* #ifdef'd out suspicious looking code (see
http://openbios.org/pipermail/linuxbios/2005-June/011759.html)
* Added optional run-time checking of dual-channel compatibility of
installed DIMMs
* Move JEDEC SPD and SDRAM definitions into reusable #include files
Probably, the rewritten code should be reviewed as if it were new. My
hope is that it is now easy enough to follow that this shouldn't be too
bad.
The original code is, of course, in Subversion. Since I reordered the
functions as part of the rewrite, a 'diff' of of the new code against
the original won't tell you much. I've attached a reordered copy of the
Subversion code that won't compile, but should be a little easier to
diff against the new code so you can see what's changed.
I will hold off on committing this for awhile to give people time to
look at it. I know that radical changes are a pain to review, but IMHO
the improvement in maintainability is significant.
New files that are part of this 'patch', but not included here (I
committed these to Subversion): src/include/spd.h
src/include/sdram_mode.h src/include/northbridge/intel/e7501/e7501.h

#include <standard.disclaimer>
It has come to the awareness of many (apparently *after* I did my talk
at the summit) that the mini-config-language is quite useful and indeed
necessary unless we want a bunch of really ugly, duplicated makefile
code scattered through our codebase, and (most) people have come to the
realization that they don't want to handwrite static C initialization
structures unnecessarily.
So, by request, I've modified the old pseudo-BNF for the config language
and appended it to this message with the (initial) changes to include in
the "new" language.
This is by no means complete nor formal (yet hopefully it is relatively
accurate ;).
Most of the language description matches what we currently have, but
I've also added many of the changes I deem necessary (mostly from common
sense). There are a few notes and suggestions on which I'd like some
feedback. Feel free to rant or rave on anything and furthermore share
your ideas.
Said changes are mostly small and include, but are not limited to:
- Removing unnecessary "end" statements to commands that needn't be
blocks (like 'arch')
- Combined the function of 'define' (as found in src/config/Options.lb)
as an optional part of the 'default' statement
- Limited the widespread used of 'default' for setting options
- Changed 'dir' to 'config' and 'config' to 'static' (maybe)
- Removing necessity of double-quotes surrounding strings (which may
happen to include double-quotes of their own)
- etc...
-------------------------------------------------------------------------------
New config language for LinuxBIOS
This document defines the new configuration language for LinuxBIOS.
The goals of the new language are these:
- Move from the python based configuration tool to something more
easily extensible and flexible
- Simplify parser so people can see and alter what is done
- Detail output so people can visualize the configuration tree
during the parsing process
- Implement capability for viewing and altering configuration with
Kconfig
Here is the new language. It is very similar to the old one, differing
in only a few aspects. Furthermore, effort has been put forth to make
the new configuration tool capable of parsing the syntax of the old
language.
This capability may be phased out in the near future, and replaced with
warning/error statements for configuration files not conforming to the
new language.
Pseudo-BNF extensions key:
Elements in angled brackets (<>) are nonterminal symbols;
items within braces ({}) are for clarification and do not represent
grammar, double-quotes ("") denote literal strings required in the text,
elements in single-quotes ('') are keywords picked up by the parser,
and a postfixed asterisk (*) denotes optionally repeatable blocks.
# Expressions are composed of terms acted upon by operators
# (unary or binary).
# They may optionally be surrounded by parentheses.
# (Preferably, surrounding parentheses may soon be required syntax - ?)
expr ::= ["("] ( unary-op term ) |

# Default assignments may optionally be followed on subsequent lines

I attach a patch file for the Via Epia-m target which makes this target now
compile and work.
I have tried to keep all changes local to the directories relevent to this
target i.e.
- mainboard/via/epia-m
- northbridge/via/vt8623
- southbridge/via/vt8623
- southbridge/ricoh
- superio/via/vt1211
- targets/via/epia-m
However there are 4 files which are modified elsewhere in the sources:
- devices/cardbus_device.c - which needed another io resource probing -
comments suggest no-one else is using this anyway
- include/device/cardbus.h - to include another function definition
- cpu/via/model_centaur/model_centaur.c - to add more processor id codes and
to get it to set up mtrr's
- arch/i386/lib/cpu.c - to conditionally test for SMP & IOAPIC systems -
this board/processor has no APIC's and would otherwise fail on the call to
lapicid()
In addition to making it work again, I have added the following
functionality:
- Dynamic memory sizing - which has been tested so far with:
- - 256Mb 1 bank (i.e. single sided)
- - 256Mb 2 bank (i.e. double sided)
- - 512Mb 2 bank (i.e. double sided)
- A minimalist ACPI dsdt table free of any intellectual property and can
thus be distributed with sources.
- Compact Flash boot working.
- I have also written an EPIA-M howto which I have attached seperately.
Maybe that can get onto the web site.
Things still not resolved:
I spent a great deal of time trying to get the vga to initialise through the
emulator, but I have failed. I feel that I now know the workings of the
emulator inside out, but it would take a good deal more effort to resolve
the issues.
As an interim solution, therefore, I have re-implemented the old real mode
vga-bios.c which works a treat on this board. To keep the main source tree
clean of this, it is implemented locally within the mainboard/via/epia-m
directory, and in a way which does not require any changes to the main
source tree (e.g. it implements its own temporary gdt's and idt's). Maybe
one day I shall return to this problem.
Whilst attempting to get the emulator to work, I had to start using a
fallback only image for sizing reasons, and this is how the patch is
configured. Without both real-mode vga and the emulator it may be possible
to go back to a dual image.
My original epia-m port set up 2 mtrr's over the vga framebuffer and agp
bridge as per the Award bios, and this makes a noticeable difference in
performance. Without changing the current mtrr stuff I see no way of making
a request for these to be set up, and so this version doesn't attempt to. It
would be nice to see this sort of functionality return into the core if
anyone is interested - perhaps as another type of memory resource different
to main memory and non contiguous from main memory. The type of these mtrr's
is write combining rather than write back as used for main memory.

I have tried latest code..., except that, it works well.

Have you tried it with 2.6.14? It has some new code to handle
high apic ids better

The timer is wired different on nvidia than on 8111. They can
go either through the 8259 or through the IOAPIC. There is still
some code that falls back to the 8259 if IOAPIC doesn't work,
which may make it appear working on Nvidia.
As a warning I'm about to remove that code so don't rely on it.

They change when interrupt 0 fires. So it's probably misrouted
or similar.

Greets,
I've made some modifications locally here to the amdk8 memory code and
wanted to just chuck them out there to see what you guys think:
1 - Renamed DIMM_SOCKETS define to DIMM_SOCKETS_PER_CHANNEL since thats what
it actually is.
2 - Added 'channel0_pop' and 'channel1_pop' to 'struct mem_controller' and
modified 'raminit.c' to fill this in with the physical DIMM population map.
For us knowing the detected DIMM population map *at the mainboard level* is
very usefull.
Fire away ;)

No
1. CONFIG_USE_INIT==0 is very useful for debug.
2. CONFIG_USE_INIT==1 is something ppc car using...
Auto.c and cache_as_ram_auto.c is very different
1. cache_as_ram_auto include failover.c
2. later cache_as_ram_auto will have struct sys_info sysinfox, and it

Is there any reason we need two different ways to do it? If both of them
are as good, can we drop one and support just the other?
BTW, after reading your patch, I found there is very little difference
between auto.c and cache_as_ram_auto.c. Most of the differences are in
the included files, can we merge auto.c and cache_as_ram_auto.c?
