2011-03-06Prep version for next release.Kevin O'Connor1-1/+1
2011-02-28Update version to 0.6.2Kevin O'Connor1-1/+1
2011-01-29Support non-local build directory - allow "make OUT=abc/" to work.Kevin O'Connor1-1/+2
Don't require the build directory to be the "out/" directory of the SeaBIOS source.
2011-01-29The vgabios build must depend on autoconf.h.Kevin O'Connor1-1/+1
2011-01-29fix parallel compilation of SeaBIOSStefan Reinauer1-1/+4
See patch. Signed-off-by: Stefan Reinauer <reinauer@google.com>
2011-01-29Start using Kconfig to configure SeaBIOS settings.Kevin O'Connor1-3/+11
Create autoconf.h during the build. Move a couple of config settings from config.h to Kconfig.
2011-01-29Build changes for Linux kconfig code to work in seabios dir structure.Kevin O'Connor1-1/+16
2010-12-26Minor build fixes.Kevin O'Connor1-1/+1
I made these two tiny changes to SeaBIOS when I was playing with the HEAD version. The Makefile change prevents the test command from failing if CC contains a space. The coreboot change prevents a warning on our gcc 4.5.2 in certain circumstances when sizeof seems to be unsigned long int instead of unsigned int. They're both unintrusive, shouldn't have potential for breaking anything. Signed-off-by: Stefan Reinauer <stepan@coreboot.org>
2010-12-05add ahci supportGerd Hoffmann1-1/+1
This patch adds AHCI support to seabios. Tested with virtual hardware only (upcoming ahci support in qemu). Coded by looking at the recommandations in the intel ahci specs, so I don't expect much trouble on real hardware. Tested booting fedora install from hard disk and a opensuse live iso from cdrom. [ v2: disable by default ] [ v2: add check for malloc failure ] [ v2: wind up disk write support ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2010-11-13pci: introduce pci_region to manage pci io/memory/prefmemory regions.Isaku Yamahata1-1/+2
This patch adds helper functions to manage pci area. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
2010-09-15Try to hard-reboot on rerun of post even on emulators.Kevin O'Connor1-3/+3
Extend the hard-reboot logic to qemu and kvm. On qemu, a reboot will not reset the memory settings for 0xc0000-0xfffff, so copy that memory area manually before rebooting. Unfortunately, kvm does not keep a pristine copy of the BIOS at 0xffff0000, so detect that case and shutdown the machine.

2010-07-10seabios: pciinit: use pci device initializer helper function.Kevin O'Connor1-1/+1
This patch makes use of pci device initialization helper function to convert if/switch clause to table driven. So this makes it easier to add q35 initialization code. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
2010-06-28Initial bootsplash support.Kevin O'Connor1-1/+1
Support displaying a jpeg file (stored in cbfs) during bootup. Signed-off-by: Stefan Reinauer <stepan@coresystems.de>
2010-06-10seabios: remove iasl output file when error.Isaku Yamahata1-4/+6
Surprisingly iasl creates output file even when compilation error. So typing make after an error will succeed. This patch prevents it by removing the output file when error. And adds related dependencies to compile when .hex is missing. Signed-off-by: Kevin O'Connor <kevin@koconnor.net> Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
2010-05-23Allow wait_irq to be called in 32bit code.Kevin O'Connor1-1/+1
If wait_irq() is called from 32bit code, then jump to 16bit mode for the wait. Have wait_irq check for threads, and have it use yield if threads are pending. This ensures threads aren't delayed if anything calls wait_irq. Use wait_irq() in 32bit mode during a failed boot.
2010-05-10Support for booting from virtio disksGleb Natapov1-1/+2
This patch adds native support for booting from virtio disks to Seabios. Signed-off-by: Gleb Natapov <gleb@redhat.com>
2010-05-01Simplify build by manually resolving external symbols in layoutrom.py.Kevin O'Connor1-17/+10
Enhance tools/layoutrom.py to explicitly set those symbols that resolve to a different code chunk (eg, 16, 32seg, 32flat). This eliminates the need to link the code chunks multiple times. This patch reduces the dependency on binutils behavior and makes the build simpler to understand.
2010-03-28Prep version for next release.Kevin O'Connor1-1/+1
2010-03-26Update version to 0.6.0.Kevin O'Connor1-1/+1
2010-03-20Disable inlining on old compilers.Kevin O'Connor1-1/+1
If the compiler can't restrict inlining by stack usage, then disable inlining in 16bit mode. Otherwise, old compilers produce code that uses too much stack space.
2010-03-09Add USB EHCI controller support.Kevin O'Connor1-1/+1
Initial support for EHCI high-speed USB controllers.
2010-02-28Only compile usb-hub.c and paravirt.c with 32bit code.Kevin O'Connor1-2/+2
Those files are only used by 32bit code, so don't bother including them with the 16bit code.
2010-02-17Initial support for booting from USB drives.Kevin O'Connor1-1/+1
This patch adds initial support for USB Mass Storage Controllers. This includes support for bulk transfers on UHCI controllers. Code to detect a USB MSC device is added, and wrappers for sending "cdb" block commands over USB are added. The scsi "inquiry" command is also added.
2010-02-17Move common "command data block" functions to new file blockcmd.c.Kevin O'Connor1-1/+1
Move common "cdb" request functions to a new file.
2010-02-15Initial support for USB hubs.Kevin O'Connor1-1/+1
Add support for detecting, initializing, and enumerating USB hubs.
2010-01-10Prep version for next release.Kevin O'Connor1-1/+1
2010-01-08Update version to 0.5.1Kevin O'Connor1-1/+1
2010-01-03Fix vgahook sign issue; add warning to build to catch future cases.Kevin O'Connor1-1/+2
2010-01-03Be sure to add "void" to all function prototypes that take no args.Kevin O'Connor1-6/+6
Omitting "void" leads to a K&R style declaration which was not intended.
2010-01-01Implement native 32bit APM support.Kevin O'Connor1-1/+1
Add APM code to 32bit segmented code. Use 32bit APM code instead of jumping into 16bit mode.
2009-12-30Add support for 32bit PCI BIOS entry.Kevin O'Connor1-13/+26
Create a new code blob (code32seg) with support for 32bit functions that need to utilize explicit segment accesses. This code blob uses global variables relative to %gs and with a dynamic code offset (determined by get_global_offset()). Add BIOS32 structure and code. Add code for 32bit PCI BIOS code.
2009-12-26Introduce MODESEGMENT define; rename VISIBLE32 to VISIBLE32FLAT.Kevin O'Connor1-14/+14
Prepare for support of segmented 32bit code. Add new MODESEGMENT definition, and clarify existing 32bit mode defs.
2009-12-19Increase version in preparation for next release.Kevin O'Connor1-1/+1
2009-12-18Update version to 0.5.0.Kevin O'Connor1-1/+1
2009-12-13Enhance experimental option rom "threading" - enable preemption.Kevin O'Connor1-1/+1
When experimental support for parallelizing option roms and hardware init (default disabled) is selected, add support for checking on hardware init progress from the RTC irq handler. Enable ability for RTC to be turned on for additional users. Allow regular option roms (not just vga option roms) to run in parallel with hardware init. Don't use stack in transition32 / transition16 until new mode is entered. Also, cleanup leaking of data handlers in usb code. Also, decrease frequency of iomemcpy checks (every 2K instead of 1K).
2009-12-10Move stack manipulation code from util.c to new file stacks.c.Kevin O'Connor1-1/+1
Move the threading and stack_hop code to a new file.
2009-11-03Reorder source code to work around weird -combine issue.Kevin O'Connor1-4/+4
Seeing an odd issue with ZoneTmpHigh not being declared global - for now, work around by reordering the soruce files. Also, remove the ".comment" section from the final .elf file.
2009-10-12Add stubs for USB OHCI support.Kevin O'Connor1-1/+1
Enable USB wrapper functions to call either ohci or ehci helpers. Implement pci_config_maskw in place of pci_set_bus_master. Introduce 'struct usb_pipe' in place of 'void *' for pipes.
2009-10-08Add rule to compile DSDT to make file.Kevin O'Connor1-0/+7
Signed-off-by: Gleb Natapov <gleb@redhat.com>
2009-10-04Move qemu config code from smbios.c to its own files. Add support forKevin O'Connor1-1/+1
-boot menu=on|off qemu option. Signed-off-by: Gleb Natapov <gleb@redhat.com>
2009-09-28Initial support for USB, UHCI, and USB Keyboards.Kevin O'Connor1-2/+3
This adds preliminary support for USB controllers and keyboards. Add support for UHCI controllers. Add support for "HID" USB keyboards. Also, fix bug in hexdump() - len need not be power of 4.
2009-09-20Allow rom to grow beyond 64K.Kevin O'Connor1-23/+18
If rom is over 64K then use part of e-segment for 32bit code. Push 32bit code as high as it can go in the f-segment. Do version building before layoutrom.py - this way layoutrom knows full size of rom. Make layoutrom.py build the full ld script - remove now unused ld scripts that just imported the output of layoutrom.py. Also, use "objdump" instead of "nm" - reduce toolchain requirements. Enhance tools/checkrom.py so that it can pad bios.bin to size qemu is happy with. Also, add dependencies to build rules for local tools - if tool changes automatically rerun it. Make sure option roms don't overwrite the 32bit code (should the 32bit code be in the e-segment). Make sure shadow code works even if part of the code is in the e-segment.
2009-09-08Prep version id for next release.Kevin O'Connor1-1/+1
2009-09-08Note version 0.4.2.Kevin O'Connor1-1/+1
2009-08-16Add support for using floppy images in CBFS.Kevin O'Connor1-1/+1
Add new "ramdisk" type for disk accesses. Extract out high-mem finding code from pmm into find_high_area(). Fix bug in GDB_BASE and GDT_LIMIT macros (wrong bit shifts).
2009-08-11Separate ATA code from generic disk code.Kevin O'Connor1-1/+1
Move generic code from ata.c to new file block.c. Rename atabits.h to ata.h and move ata header definitions from disk.h. Rename ATA.channels to ATA_channels. Rename ATA structure to Drives. Support both CONFIG_DRIVES and CONFIG_ATA options.
2009-07-29Add auto-generated version info to each build.Kevin O'Connor1-2/+7
Add versioning info to initial debug and screen banner output.
2009-07-26Add PMM stubs.Kevin O'Connor1-1/+1
Add initial code for Post Memory Manager - it's just the stubs for now. Also, fix PnP entry point not clearing irqs and direction flags.
