7 years 5 months Support Samsung SE-S084 USB DVD drive (and probably many others)

A full implementation of ATAPI USB support would need to translate / filter
certain package types or some devices might not work. No previously working
devices break with the patch, so it is fine to commit.

7 years 5 months Enhance tools/readserial.py to support reading from a pipe.

Add option parsing support to tool.

Enable option (-f) to read from a pipe - which is useful when
redirecting qemu's debugging log to a pipe with:
-chardev pipe,id=seabios,path=seabioslog -device isa-debugcon,iobase=0x402,chardev=seabios

7 years 5 months Update qemu_cfg_read to use "rep insb".

Use rep insb instead of manual loop - the host may be able to optimize
the rep insb instruction.

7 years 5 months Only show bootsplash during boot menu.

When the bootsplash picture is shown, it's not possible to see text.
So, only display the picture while prompting the user for the boot
menu.

7 years 5 months add write support to virtio-blk

Windows XP does write to sector 0 during installation and prints
mysterious error if write fails. Interestingly if write drops data,
but returns OK to Windows installer installation proceed without
complains and completes successfully.

7 years 6 months Don't try to talk to APIC on 486

It only has one cpuid level, therefore it can't report whether it
has an APIC. It probably hasn't; assume that. Without this,
SeaBIOS would get stuck on qemu -M isapc.

7 years 6 months Add ACPI SSDT/DSDT support for CPU hotplug.

Move the SSDT defined processors from _PR to _SB namespace.

Extend the dynamically generated SSDT to include per cpu hotplug
methods. These methods just call methods defined in the DSDT. Also
dynamically generate a NTFY method and a CPON array of the
online/available CPUs. Add file src/ssdt-proc.dsl with directions for
generating the per-cpu processor object AML code.

Extend the DSDT to include methods for handling cpu hotplug
notifications and methods for handling cpu status requests originating
from the SSDT methods.

7 years 6 months Allow qemu to use bootsplash code via fwcfg interface.

All the bootsplash code to pull the jpeg file from either cbfs (on
coreboot) or fwcfg (on qemu).

7 years 6 months Add tools/trandump.py tool for converting hexdump() output.

Add tool for converting the output from hexdump() back into its
original binary form. This can be useful for use with tools such as
hexdump and objdump.

7 years 6 months Default bootsplash on (for coreboot users).
Commit 48f5f8b850d19767f60ee83bfe0fd30bc4e867b4, by Kevin O'Connor
7 years 6 months Autodetect video mode based on bootsplash jpeg dimensions.

Replace video mode settings in config.h with a system to auto-detect a
video mode for the given bootsplash.jpg file.

7 years 6 months Rename "decdata" to "jpeg" in bootsplash - to be consistent with jpeg.c.

Also rename "jpeg" to "filedata" to avoid a conflict.
Commit b2b9d4a6b682a7aac9d0ad8d857ee6fcfb4f9e1f, by Kevin O'Connor
7 years 6 months Breakup jpeg_decode into parsing and displaying phases.

Split the screen display code out of the jpeg parsing code.

Allow ability for caller to obtain jpeg dimensions.

7 years 6 months Avoid using BSS variables in jpeg.c.

Using BSS increases the rom size (and reduce space for option roms).
So, move BSS variables in the jpeg.c code to malloc'd memory.

Also, move struct and error declarations from jpeg.h to jpeg.c.

7 years 6 months Handle unaligned sizes in iomemcpy().

This fixes a bug causing truncation of uncompressed files in
cbfs_copyfile().

7 years 6 months Be sure to disable bootsplash on all BIOS boot cases.

Disable the bootsplash on cbfs payload exec, and if something hooks
int19.

Also, be sure to only disable the bootsplash (revert to text mode)
once.

7 years 6 months Don't do "double buffering" in bootsplash code.

Not all vgabios support off screen framebuffers. Instead, decompress
the picture into ram, and then copy it into the framebuffer. This
ensures a fast display time without requiring any special vga support.
