* seabios: pciinit: use pci device initializer helper function.Kevin O'Connor2010-07-101-1/+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>
* Initial bootsplash support.Kevin O'Connor2010-06-281-1/+1
| | | | | | Support displaying a jpeg file (stored in cbfs) during bootup. Signed-off-by: Stefan Reinauer <stepan@coresystems.de>
* seabios: remove iasl output file when error.Isaku Yamahata2010-06-101-4/+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>
* Allow wait_irq to be called in 32bit code.Kevin O'Connor2010-05-231-1/+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.
* Support for booting from virtio disksGleb Natapov2010-05-101-1/+2
| | | | | | This patch adds native support for booting from virtio disks to Seabios. Signed-off-by: Gleb Natapov <gleb@redhat.com>
* Simplify build by manually resolving external symbols in layoutrom.py.Kevin O'Connor2010-05-011-17/+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.

* Disable inlining on old compilers.Kevin O'Connor2010-03-201-1/+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.
* Add USB EHCI controller support.Kevin O'Connor2010-03-091-1/+1
| | | | Initial support for EHCI high-speed USB controllers.
* Only compile usb-hub.c and paravirt.c with 32bit code.Kevin O'Connor2010-02-281-2/+2
| | | | | Those files are only used by 32bit code, so don't bother including them with the 16bit code.
* Initial support for booting from USB drives.Kevin O'Connor2010-02-171-1/+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.
* Move common "command data block" functions to new file blockcmd.c.Kevin O'Connor2010-02-171-1/+1
| | | | Move common "cdb" request functions to a new file.
* Initial support for USB hubs.Kevin O'Connor2010-02-151-1/+1
| | | | Add support for detecting, initializing, and enumerating USB hubs.

* Fix vgahook sign issue; add warning to build to catch future cases.Kevin O'Connor2010-01-031-1/+2
|
* Be sure to add "void" to all function prototypes that take no args.Kevin O'Connor2010-01-031-6/+6
| | | | Omitting "void" leads to a K&R style declaration which was not intended.
* Implement native 32bit APM support.Kevin O'Connor2010-01-011-1/+1
| | | | | Add APM code to 32bit segmented code. Use 32bit APM code instead of jumping into 16bit mode.
* Add support for 32bit PCI BIOS entry.Kevin O'Connor2009-12-301-13/+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.
* Introduce MODESEGMENT define; rename VISIBLE32 to VISIBLE32FLAT.Kevin O'Connor2009-12-261-14/+14
| | | | | Prepare for support of segmented 32bit code. Add new MODESEGMENT definition, and clarify existing 32bit mode defs.

* Enhance experimental option rom "threading" - enable preemption.Kevin O'Connor2009-12-131-1/+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).
* Move stack manipulation code from util.c to new file stacks.c.Kevin O'Connor2009-12-101-1/+1
| | | | Move the threading and stack_hop code to a new file.
* Reorder source code to work around weird -combine issue.Kevin O'Connor2009-11-031-4/+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.
* Add stubs for USB OHCI support.Kevin O'Connor2009-10-121-1/+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.
* Add rule to compile DSDT to make file.Kevin O'Connor2009-10-081-0/+7

* Move qemu config code from smbios.c to its own files. Add support forKevin O'Connor2009-10-041-1/+1
| | | | | | -boot menu=on|off qemu option. Signed-off-by: Gleb Natapov <gleb@redhat.com>
* Initial support for USB, UHCI, and USB Keyboards.Kevin O'Connor2009-09-281-2/+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.
* Allow rom to grow beyond 64K.Kevin O'Connor2009-09-201-23/+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.

* Add support for using floppy images in CBFS.Kevin O'Connor2009-08-161-1/+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).
* Separate ATA code from generic disk code.Kevin O'Connor2009-08-111-1/+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.
* Add auto-generated version info to each build.Kevin O'Connor2009-07-291-2/+7
| | | | Add versioning info to initial debug and screen banner output.
* Add PMM stubs.Kevin O'Connor2009-07-261-1/+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.
* Expand int155f "vgahook" detection.Kevin O'Connor2009-07-191-2/+2
| | | | | | Verify VGA card vendor is via before supporting via 155f calls. Add support for future code depending on coreboot board id. Add code for via VX855 memory size and speed detection.
* Minor - clarify intermediate object file names.Kevin O'Connor2009-07-131-11/+13
| | | | | Rename romlayout16.o to code16.o. Rename ccode32.o to code32.o.
* Don't use "objcopy --extract-symbol" - old binutils don't have that option.Kevin O'Connor2009-06-221-1/+1
|
* Forward port bochs smp changes; rename smpdetect.c to smp.c.Kevin O'Connor2009-06-211-1/+1
| | | | | | | | | | Rename smpdetect.c to smp.c - the code does more than just cpu detection. Don't probe cpu count on demand - schedule it during post. Add logic to run wrmsr on all cpus. Don't make mtrr setup specific to kvm - do it on all machines that have mtrr and msrs. Detect cpu signature/features automatically in mptable. Also, make sure acpi structures are packed.
* Avoid makefile "else ifeq" syntax - old versions don't support it.Kevin O'Connor2009-06-171-1/+3
|
* Avoid -fwhole-program on broken gcc instead of stopping build.Kevin O'Connor2009-06-151-9/+16
| | | | | Enhance build to detect and avoid gcc with broken -fwhole-program Also, remove workaround for older gcc that mess up global exports.
* Add support for gcc v3.x compilers.Kevin O'Connor2009-06-101-2/+4
| | | | | | | | Suppress __attribute__((externally_visible)) when no -fwhole-program Add switch hack for compilers without -fno-jump-tables Define memcpy() function (for compilers without -minline-all-stringops). Define call16_simpint as a macro (a param needs to be inlined). Make sure s3_resume is only defined in 32bit mode.
* Do garbage collection of unused sections.Kevin O'Connor2009-06-101-5/+8
| | | | | | | | | | | Implement -ffunction-sections and -fdata-sections in both 32bit and 16bit code. Make sure all sections have unique names (even asm and discarded sections). Enhance tools/layoutrom.py script to find all sections reachable from exported 16bit code - prune all other sections. Mark sections with "export" if they can be visible outside of code - these sections wont be dropped when pruning unused sections.
* Keep relocated 16bit code so checkstack can use it.Kevin O'Connor2009-05-271-2/+2
| | | | | Make was stripping the relocated 16bit code - keep the unstripped 16bit code so that checkstack can parse it.
* Eliminate "_code32_" prefix on 32bit symbols referenced from 16bit code.Kevin O'Connor2009-05-231-9/+11
| | | | Use linking magic to eliminate the need for the _code32_ prefix.
