Introduction
|
|
------------
|
|
|
|
This configuration offers a cross-build of (a subset of) the build-bootstrap
|
|
package selection for the sparc architecture as emulated by qemu-system-sparc.
|
|
It includes support for all the hardware emulated by qemu, a working udev,
|
|
kernel and userland support for TCP/IP networking, and more.
|
|
|
|
With qemu and the resulting build you can at least:
|
|
- boot the kernel and first stage initrd,
|
|
- execute a shell from the initrd,
|
|
- load the second stage from a CD-ROM,
|
|
- and install packages from the CD on a hard disk using the stone installer.
|
|
|
|
The packages included should be sufficient for native builds on the targeted
|
|
platform.
|
|
|
|
Quick Start
|
|
-----------
|
|
|
|
- Boot from CD with framebuffer console:
|
|
qemu-system-sparc -cdrom bbs-sparc-qemu_cd1.iso -hda /srv/qemu.hda \
|
|
-boot d
|
|
|
|
- Boot from CD with serial console:
|
|
qemu-system-sparc -cdrom bbs-sparc-qemu_cd1.iso -hda /srv/qemu.hda \
|
|
-boot d -append "console=ttyS0 video=tcxfb:off" -nographic

Hints And Known Bugs
|
|
--------------------
|
|
|
|
- To use the CD image in qemu, create it after the build has finished:
|
|
./scripts/Create-ISO bbs-sparc-qemu bbs-sparc-qemu
|
|
|
|
- To use a hard disk in qemu, create it with e.g.:
|
|
qemu-img create /srv/qemu.hda 2048M
|
|
|
|
- When using a console on the serial port, be sure to enter 'ttyS0' as the
|
|
terminal device in boot stage 2, or you won't get to see the command line.
|
|
|
|
- glibc26 does not build for sparc with -Os because extern inline functions are
|
|
not used when optimizing for size, resulting in a missing __ieee754_sqrtl
|
|
function for libm_pic.a; glibc-2.6/sysdeps/sparc/sparc32/fpu/e_sqrtl.c
|
|
is compiled but glibc-2.6/sysdeps/sparc/sparc32/soft-fp/q_sqrt.c contains
|
|
the actual __ieee754_sqrtl function.
|
|
|
|
- the SCSI support in kernel is not compiled as a module because udev can't
|
|
load it automatically, and loading it and creating the /dev entries manually,
|
|
the SCSI devices don't work. Furthermore, if partitioning a previously empty
|
|
hard disk, the new partitions won't show up until after a reboot.
|
|
|
|
- the size of the uncompressed kernel image (/boot/image) is limited to 2,5 MB
|
|
when booting with silo.
|
|
|
|
- strace does not (cross-)build for sparc yet.
