new config language
by ron minnich 06 Jun '03

06 Jun '03

comments welcome. This doc is in the RFC section. ron New config language for LinuxBIOS \begin{abstract} We describe the new configuration language for LinuxBIOS. \end{abstract} \section{Scope} This document defines the new configuration language for LinuxBIOS. \section{Goals} The goals of the new language are these: \begin{itemize} \item Simplified Makefiles so people can see what is set \item Move from the regular-expression-based language to something a bit more comprehensible and flexible \item make the specification easier for people to use and understand \item allow unique register-set-specifiers for each chip \end{itemize} \section{Language} Here is the new language. It is very similar to the old one, differing in only a few respects. It borrows heavily from Greg Watson's suggestions. I am presenting it in a pseudo-BNF in the hopes it will be easier. Things in '' are keywords; things in ``'' are strings in the actual text. \begin{verbatim} #exprs are composed of factor or factor + factor etc. expr ::= factor ( ``+'' factor | ``-'' factor | )* #factors are term or term * term or term / term or ... factor ::= term ( ``*'' term | ``/'' term | ... )* # unary-op ::= ``!'' ID # term is a number, hexnumber, ID, unary-op, or a full-blown expression term ::= NUM | XNUM | ID | unary-op | ``(`` expr ``)'' # Option command. Can be an expression or quote-string. # Options are used in the config tool itself (in expressions and 'if') # and are also passed to the C compiler when building linuxbios. # It is an error to have two option commands in a file. # It is an error to have an option command after the ID has been used # in an expression (i.e. 'set after used' is an error) option ::= 'option' ID '=' (``value'' | term) # Default command. The ID is set to this value if no option command # is scanned. # Multiple defaults for an ID will produce warning, but not errors. # It is OK to scan a default command after use of an ID. # Options always over-ride defaults. default ::= 'default' ID '=' (``value'' | term) # the mainboard, southbridge, northbridge commands # cause sourcing of Config.lb files as in the old config tool # as parts are sourced, a device tree is built. The structure # of the tree is determined by the structure of the components # as they are specified. To attach a superio to a southbridge, for # example, one would do this: # southbridge acer/5432 # superio NSC/123 # end # end # the tool generates static initializers for this hierarchy. # add C code to the current component (motherboard, etc. ) # to initialise the component-INDEPENDENT structure members init ::= 'init' ``CODE'' # add C code to the current component (motherboard, etc. ) # to initialise the component-DEPENDENT structure members register ::= 'register' ``CODE'' # mainboard command # statements in this block will set variables controlling the mainboard, # and will also place components (northbridge etc.) in the device tree # under this mainboard mainboard ::= 'mainboard' PATH (statements)* 'end' # standard linuxbios commands southbridge ::= 'southbridge' PATH (statemnts)* 'end' northbridge ::= 'northbridge' PATH (statemnts)* 'end' superio ::= 'superio PATH (statemnts)* 'end' cpu ::= 'cpu' PATH (statemnts)* 'end' arch ::= 'arch' PATH (statemnts)* 'end' # files for building linuxbios # include a file in crt0.S mainboardinit ::= 'mainboardinit' PATH # object file object ::= 'object' PATH # driver objects are just built into the image in a different way driver ::= 'driver' PATH # Use the Config.lb file in the PATH dir ::= 'dir' PATH # add a file to the set of ldscript files ldscript ::= 'ldscript' PATH # dependencies or actions for the makerule command dep ::= 'dep' ``dependency-string'' act ::= 'act' ``actions'' depsacts ::= (dep | act)* # set up a makerule # makerule ::= 'makerule' PATH depsacts #defines for use in makefiles only # note usable in the config tool, not passed to cc makedefine ::= 'makedefine' ``RAWTEXT'' # add an action to an existing make rule addaction ::= 'addaction' PATH ``ACTION'' # statements statement ::= option | default | cpu | arch | northbridge | southbridge | superio | object | driver | mainboardinit | makerule | makedefine | addaction | init | register | iif | dir | ldscript statements ::= (statement)* # target directory specification target ::= 'target' PATH # and the whole thing board ::= target (option)* mainboard \end{verbatim} A sample file: \begin{verbatim} target x # over-ride the default rom size in the mainboard file option ROM_SIZE=0x100000 mainboard amd/solo end \end{verbatim} Sample mainboard file \begin{verbatim} # ### ### Set all of the defaults for an x86 architecture ### arch i386 end cpu k8 end # option DEBUG=1 default USE_FALLBACK_IMAGE=1 option A=(1+2) option B=0xa # ### ### Build our 16 bit and 32 bit linuxBIOS entry code ### mainboardinit cpu/i386/entry16.inc mainboardinit cpu/i386/entry32.inc ldscript cpu/i386/entry16.lds ldscript cpu/i386/entry32.lds # ### ### Build our reset vector (This is where linuxBIOS is entered) ### if USE_FALLBACK_IMAGE mainboardinit cpu/i386/reset16.inc ldscript cpu/i386/reset16.lds end if USE_NORMAL_IMAGE mainboardinit cpu/i386/reset32.inc ldscript cpu/i386/reset32.lds end . . . if USE_FALLBACK_IMAGE mainboardinit arch/i386/lib/noop_failover.inc end # ### ### Romcc output ### #makerule ./failover.E dep "$(MAINBOARD)/failover.c" act "$(CPP) -I$(TOP)/src $(CPPFLAGS) $(MAINBOARD)/failover.c > ./failever.E" #makerule ./failover.inc dep "./romcc ./failover.E" act "./romcc -O ./failover.E > failover.inc" #mainboardinit ./failover.inc makerule ./auto.E dep "$(MAINBOARD)/auto.c" act "$(CPP) -I$(TOP)/src -$(ROMCCPPFLAGS) $(CPPFLAGS) $(MAINBOARD)/auto.c > ./auto.E" makerule ./auto.inc dep "./romcc ./auto.E" act "./romcc -O ./auto.E > auto.inc" mainboardinit ./auto.inc # ### ### Setup RAM ### mainboardinit ram/ramtest.inc mainboardinit southbridge/amd/amd8111/smbus.inc mainboardinit sdram/generic_dump_spd.inc # ### ### Include the secondary Configuration files ### northbridge amd/amdk8 end southbridge amd/amd8111 end #mainboardinit arch/i386/smp/secondary.inc superio NSC/pc87360 register "com1={1} com2={0} floppy=1 lpt=1 keyboard=1" end dir /pc80 ##dir /src/superio/winbond/w83627hf cpu p5 end cpu p6 end cpu k7 end cpu k8 end # ### ### Build the objects we have code for in this directory. ### ##object mainboard.o driver mainboard.o object static_devices.o if HAVE_MP_TABLE object mptable.o end if HAVE_PIRQ_TABLE object irq_tables.o end ### Location of the DIMM EEPROMS on the SMBUS ### This is fixed into a narrow range by the DIMM package standard. ### option SMBUS_MEM_DEVICE_START=(0xa << 3) option SMBUS_MEM_DEVICE_END=(SMBUS_MEM_DEVICE_START +1) option SMBUS_MEM_DEVICE_INC=1 # ### The linuxBIOS bootloader. ### option PAYLOAD_SIZE = (ROM_SECTION_SIZE - ROM_IMAGE_SIZE) option CONFIG_ROM_STREAM_START = (0xffffffff - ROM_SIZE + ROM_SECTION_OFFSET + 1) # \end{verbatim} I've found the output of the new tool to be easier to handle. Makefile.settings looks like this, for example: \begin{verbatim} TOP:=/home/rminnich/src/yapps2/freebios2 TARGET_DIR:=x export MAINBOARD:=/home/rminnich/src/yapps2/freebios2/src/mainboard/amd/solo export ARCH:=i386 export _RAMBASE:=0x4000 export ROM_IMAGE_SIZE:=65535 export PAYLOAD_SIZE:=131073 export MAX_CPUS:=1 export HEAP_SIZE:=8192 export STACK_SIZE:=8192 export MEMORY_HOLE:=0 export LINUXBIOS_VERSION:=1.1.0 export CC:=$(CROSS_COMPILE)gcc \end{verbatim} In other words, instead of expressions, we see the values. It's easier to deal with.

tusl2-c with kernel
by Yap Ee Huey 06 Jun '03

06 Jun '03

Hi all, After failing to load with both Etherboot and ADLO, I tried to reduce the size of kernel to 192k bytes ( which can only boot and execute simple command ) to fit into my 256k rom. But after "Jumping to boot code", it reboots. Does that mean my ram initialization is buggy ? Thanks.

GDT in entry16/32.inc
by Xavier Pegenaute 05 Jun '03

05 Jun '03

Hello, for curiosity is there any specific reason for put values in the first entry of GDT in the file src/cpu/i386/entry[16|32].inc ?. The content of the first entry is: .globl EXT(gdtptr) gdt: EXT(gdtptr): .word gdt_end - gdt -1 /* compute the table limit */ .long gdt /* we know the offset */ .word 0 ... etc ... Xavi. Regards.

Request for Status update of LinuxBios for SC1200 chipset
by Narendra PAtel 04 Jun '03

04 Jun '03

Dear Christer, After going through the mar2002 freebios mailing list I read about your achievement of SC1200 board working with linuxbios!!! As you mentioned in that mail that you had not tested graphics and Audio. Could you please update us with the present status of Linuxbios development for NSC's SCx2xx chipset? Does that final working code or patch being uploaded or can the final working code be available to us for our application which is very similar to Dorado II platform(SC1200 based)? Did you achieved booting WinCe using Linuxbios? Linuxbios homepage has posted one news that Linuxbios can boot windows 2000!!!! but the code is not yet posted. Thanks and regards, Narendra Patel. _________________________________________________________________ Technical writer?. Earn more now! http://server1.msn.co.in/msnleads/tis/index.asp Find out how.

by NEWBELL7＠magicn.com 04 Jun '03

04 Jun '03

Hello!! Have you seen any ps/2 problem on EPIA ? If you have PS/2 mouse & keyboard at same time on EPIA, mouse moving makes problem for ps/2 working. After that , keyboard also didn't work. If you use gpm for mouse, both of mouse & keyboard didn't work. And If you unload gpm, keyboard buffer data while using gpm print on screen suddenly. Do you know this problem? If you have any idea, let me know. please. Thank you. regards, newbie
