-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

-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).
