This directory contains the files required to build
the fake PROM image that is currently being used to
boot IA64 kernels running under the SGI Medusa kernel.
The FPROM currently provides the following functions:
- PAL emulation for all PAL calls we've made so far.
- SAL emulation for all SAL calls we've made so far.
- EFI emulation for all EFI calls we've made so far.
- builds the "ia64_bootparam" structure that is
passed to the kernel from SAL. This structure
shows the cpu & memory configurations.
- supports medusa boottime options for changing
the number of cpus present
- supports medusa boottime options for changing
the memory configuration.
At some point, this fake PROM will be replaced by the
real PROM.
To build a fake PROM, cd to this directory & type:
make
This will (or should) build a fake PROM named "fprom".
Use this fprom image when booting the Medusa simulator. The
control file used to boot Medusa should include the
following lines:
load fprom
load vmlinux
sr pc 0x100000
sr g 9 <address of kernel _start function> #(currently 0xe000000000520000)
NOTE: There is a script "runsim" in this directory that can be used to
simplify setting up an environment for running under Medusa.
The following parameters may be passed to the fake PROM to
control the PAL/SAL/EFI parameters passed to the kernel:
GR[8] = # of cpus
GR[9] = address of primary entry point into the kernel
GR[20] = memory configuration for node 0
GR[21] = memory configuration for node 1
GR[22] = memory configuration for node 2
GR[23] = memory configuration for node 3
Registers GR[20] - GR[23] contain information to specify the
amount of memory present on nodes 0-3.
- if nothing is specified (all registers are 0), the configuration
defaults to 8 MB on node 0.
- a mem config entry for node N is passed in GR[20+N]
- a mem config entry consists of 8 hex digits. Each digit gives the
amount of physical memory available on the node starting at
1GB*<dn>, where dn is the digit number. The amount of memory
is 8MB*2**<d>. (If <d> = 0, the memory size is 0).
SN1 doesn't support dimms this small but small memory systems
boot faster on Medusa.
An example helps a lot. The following specifies that node 0 has
physical memory 0 to 8MB and 1GB to 1GB+32MB, and that node 1 has
64MB starting at address 0 of the node which is 8GB.
gr[20] = 0x21 # 0 to 8MB, 1GB to 1GB+32MB
gr[21] = 0x4 # 8GB to 8GB+64MB

* - determine the base address of the node it is loaded on
* - add the node base to _gp.
* - add the node base to all addresses derived from "movl"
* instructions. (I couldnt get GPREL addressing to work)
* (maybe newer versions of the tools will support this)
* - scan the .got section and add the node base to all
* pointers in this section.
* - add the node base to all physical addresses in the
* SAL/PAL/EFI table built by the C code. (This is done

Script for running a PROM or LINUX kernel under medusa.
This script creates a control file, creates links to the appropriate
linux/prom files, and/or calls medusa to make simulation runs.
Usage:
Initial setup:
sim [-c <config_file>] <-p> | <-k> [<work_dir>]
-p Create PROM control file & links
-k Create LINUX control file & links
-c<cf> Control file name [Default: cf]
<work_dir> Path to directory that contains the linux or PROM files.
The directory can be any of the following:
(linux simulations)
worktree
worktree/linux
any directory with vmlinux, vmlinux.sym & fprom files
(prom simulations)
worktree
worktree/stand/arcs/IP37prom/dev
any directory with fw.bin & fw.sim files
Simulations:
sim [-X <n>] [-o <output>] [-M] [<config_file>]
-c<cf> Control file name [Default: cf]
-M Pipe output thru fmtmedusa
-o Output filename (copy of all commands/output) [Default: simout]
-X Specifies number of instructions to execute [Default: 0]
(Used only in auto test mode - not described here)
Examples:
sim -p <promtree> # create control file (cf) & links for prom simulations
sim -k <linuxtree> # create control file (cf) & links for linux simulations
sim -p -c cfprom # create a prom control file (cfprom) only. No links are made.
sim # run medusa using previously created links &
# control file (cf).
