Autors	SHA1	Ziņojums	Datums
Michael Brown	07e11f8af9	Minor debug improvement	18 gadus atpakaļ
Michael Brown	2cfe0dee1f	Don't trash the %ecx value returned by relocate(). This was causing us to round down the size for the relocation copy to the nearest 64kB (+0x10 bytes); this just happened to work on most machines because the last 64kB of the image is all-zeroes anyway (it's the .bss).	18 gadus atpakaļ
Michael Brown	a8111e8ab7	Remove INT 13,4b handler; it represents an incomplete feature (CD-ROM emulation support) for an unknown purpose, and breaks grub.	18 gadus atpakaļ
Michael Brown	0d9d2ccbae	Completed definition of struct int13_cdrom_specification, and moved to int13.h.	18 gadus atpakaļ
Michael Brown	013d381e3c	Real-mode code might set the direction flag, which would cause carnage.	18 gadus atpakaļ
Michael Brown	c94cdf2b7d	Move .zinfo to libprefix.S; it doesn't belong with the decompression code.	18 gadus atpakaļ
Michael Brown	dc52db4920	Removed dead code identified by symcheck	18 gadus atpakaļ
Michael Brown	38dbe14bbe	Kill off redundant references to the .zprefixes.	18 gadus atpakaļ
Michael Brown	84551d485e	Update all prefixes currently referring to _load_size to include a compressor fixup section.	18 gadus atpakaļ
Michael Brown	0929142a15	Rename _rom_size to _load_size_sect, since hdprefix.S also uses it.	18 gadus atpakaļ
Michael Brown	048bbeeebc	Compressed ROM images now work.	18 gadus atpakaļ
Michael Brown	6d2e4e719c	Move uninitialised .data16 variables to .bss16; saves around 2000 bytes of useless zeroes in the final image.	18 gadus atpakaļ
Michael Brown	389204713f	Kill off some long-redundant CFLAGS	18 gadus atpakaļ
Michael Brown	833d6cc8ec	Add __bss16() macro, and allow use of .bss16 section by removing link-time check for section overlaps. (In order to avoid wasting space in the executable image, .bss16 will overlap with the following section, which is .text).	18 gadus atpakaļ
Michael Brown	ab859a5355	Use a single _payload_offset linker-defined variable to locate the start of the non-prefix blocks in the loaded image, and rely on the image ordering. This should make introducing compression much easier.	18 gadus atpakaļ
Michael Brown	0b5059c40b	Skip the length field prepended by util/nrv2b.c	18 gadus atpakaļ
Michael Brown	b37e267d1b	Modified calling convention: we now update %esi and %edi just like a "rep movsb".	18 gadus atpakaļ
Michael Brown	3feac9465e	"not" doesn't affect flags, "xor $-1" does.	18 gadus atpakaļ
Michael Brown	26473105cd	On advice of hpa: be more patient with the KBC and SCPA methods; retry in a long loop before giving up on them. Record method which worked and default to that method on next attempt.	18 gadus atpakaļ
Michael Brown	adf192f566	Shrink cpu.c and render it useful for our purposes.	18 gadus atpakaļ
Michael Brown	e330db3c74	Dead code removal. Kill off use of etherboot.h outside drivers/net.	18 gadus atpakaļ
Michael Brown	95c07736cb	Be more aggressive in attempts to enable A20, now that we have the optimisation of only trying to do so when necessary.	18 gadus atpakaļ
Michael Brown	8624fdc445	Kill off the enforced RX quota; it only seems to hurt on real hardware.	18 gadus atpakaļ
Michael Brown	57b5e227ff	Use fast in-situ test for gate A20 being set, to cut down on the number of (potentially very slow) gateA20_set operations. Die with a fatal error if we are unable to set gate A20; if this fails then we are bound to experience memory corruption at a later stage, and I'd prefer to pick it up early.	18 gadus atpakaļ
Michael Brown	2ac7694c3e	Improve error reporting for strange length combinations reported by the UNDI stack. Ignore obviously invalid length combinations (as returned by e.g. VMWare's PXE stack). Limit to one packet per poll to avoid memory exhaustion.	18 gadus atpakaļ
Michael Brown	efd322091d	Set up %ds before testing a value in our data segment (d'oh!). Always send EOI; do not chain to BIOS's default interrupt handler. They are just too unpredictable; at least VMware's seems to kill the machine if you go anywhere near it. Disable interrupts after return from PXENV_UNDI_ISR, just in case some dumb PXE stack enables them.	18 gadus atpakaļ
Michael Brown	f6f9a3098d	Report RX errors via netdev_rx_err()	18 gadus atpakaļ
Michael Brown	fb16f90699	Dump first 64 bytes of chained ISR when debugging is enabled.	18 gadus atpakaļ
Michael Brown	edc4648c39	Protect ISR against failure to unhook.	18 gadus atpakaļ
Michael Brown	4e14b020a5	Master IRQ should be EOIed first, I think.	18 gadus atpakaļ
Michael Brown	19871cbb96	We probably ought not to call INT13 with interrupts disabled.	18 gadus atpakaļ
Michael Brown	027fed72c1	Working code to call the PXE stack from within the ISR.	18 gadus atpakaļ
Michael Brown	cd7e296cbe	Always increase number of BIOS drives when registering	18 gadus atpakaļ
Michael Brown	b90d321dfb	Change %dl fixup rules for INT13: INT 13,08 : read number of drives from 40:75 INT 13,15 : do nothing all others : restore original value of %dl	18 gadus atpakaļ
Michael Brown	c7d9fdb5b9	Proof of concept; works, but has several hard-coded hacks.	18 gadus atpakaļ
Michael Brown	8bce52d348	Set CF by default, clear on success (rather than clearing and setting on failure).	18 gadus atpakaļ
Holger Lubitz	4ff85d9f15	Add -mpreferred-stack-boundary=2 to i386 CFLAGS as it's almost always a win.	18 gadus atpakaļ
Michael Brown	4c418d2100	Use net_device_operations structure and netdev_nullify() to allow for safe dropping of the netdev ref by the driver while other refs still exist. Add netdev_irq() method. Net device open()/close() methods should no longer enable or disable IRQs. Remove rx_quota; it wasn't used anywhere and added too much complexity to implementing correct interrupt-masking behaviour in pxe_undi.c.	18 gadus atpakaļ
Holger Lubitz	c7549bcebe	convert to zalloc	18 gadus atpakaļ
Holger Lubitz	bb61774ee4	convert to zalloc	18 gadus atpakaļ
Michael Brown	f660e8ef58	Add strlen_user() (will be needed for PXE API extensions)	18 gadus atpakaļ
Marty Connor	28d8d828b3	Rename .lilo extension to .lkrn and updated dependencies	18 gadus atpakaļ
Michael Brown	763a3eab8a	Add .pdsk target (padded .dsk, suitable for qemu).	18 gadus atpakaļ
Michael Brown	fbda4837b0	Allocate heap at first usage, rather than assuming we can fit it in below _text. This should help with the gPXE-on-gPXE-via-PXE case.	18 gadus atpakaļ
Michael Brown	07ea125213	Use partition type 0xeb ("EtherBoot"), to avoid any attempts to mount the Etherboot partition.	18 gadus atpakaļ
Michael Brown	6e082c9b81	Add .usb target	18 gadus atpakaļ
Michael Brown	a0f078d7f5	Working with multi-sector reads	18 gadus atpakaļ
Michael Brown	66208dd65d	hdprefix that works for LBA only	18 gadus atpakaļ
Michael Brown	839960276d	Miscellaneous efficiency improvements, and extend read_sectors to handle multiple sectors.	18 gadus atpakaļ
Michael Brown	3c2d50e5de	Added active partition locator, and simple MBR built using it.	18 gadus atpakaļ
