Michael Brown ed5ff61790 Standardise DBG_PRINTF()->DBG(), and remove custom definitions for
DBG_PRINTF() and assert().
2007-09-26 17:38:36 +01:00
Michael Brown 881dd8e102 Switch rm_ss and rm_sp back to being words; it'll make it less
confusing to read the code.
2007-09-25 20:16:32 +01:00
Michael Brown 42d96bcb07 Don't use the "rep ss movsb" trick to copy the RM stack to the PM
stack; it breaks vmxassist.
2007-09-25 20:14:20 +01:00
Michael Brown 0ed066bc50 rm_ss, rm_sp, and pm_esp don't need to be accessed from anywhere
outside of librm.S.
2007-09-25 19:20:38 +01:00
Michael Brown b8a8eea850 Minor refactoring to eliminate duplication. 2007-09-25 19:06:38 +01:00

work around limitations in real-mode virtualisation support on Intel
VT-capable chips.

Michael Brown a7eee64506 Added more verbose memory-map debugging.
Added redundant call to get_memmap() in int13_boot() immediately
before jumping to boot sector, to assist in debugging.

Michael Brown 5793dbe96f Infinband requires longer link-layer addresses and headers than Ethernet. 2007-09-21 01:23:57 +01:00
Michael Brown 2ee76d0c93 Added defines for Infiniband files (which can't be committed to the
main tree yet, but reserving the error numbers now avoids problems later).
2007-09-21 01:19:04 +01:00
Michael Brown 1af346b531 Minor debug message improvement. 2007-09-21 01:17:46 +01:00

Michael Brown f09173326c Moved iobuf.h assertions outside the static inline functions, so that
the assert message's file and line number gives some clue as to the
real location of the problem.

Added similar assertions to list.h.
2007-09-21 01:13:22 +01:00
Michael Brown 0f60150c44 Reverted driver/net/mlx_ipoib to clean master state 2007-09-18 07:07:04 +01:00
Michael Brown 30717896f5 IB can't afford many RX buffers, because the MTU is so large. Reduce
the TCP window to compensate.
2007-09-18 07:02:41 +01:00

crash the machine.
2007-09-17 19:47:19 +01:00
Michael Brown 12b4cb964b Removed more hacks, and adjusted number of queue entries for likely usage. 2007-09-17 19:17:55 +01:00
Michael Brown 11541b1e01 Remove hacks, and fix leaving the multicast GID. 2007-09-17 19:12:06 +01:00
Michael Brown 267a4483ab Added an almost obscene amount of debugging and assertion code while
tracking down a bug that turned out to be a free_iob() used where I
needed a netdev_tx_complete().  This left the freed I/O buffer on the
net device's TX list, with bad, bad consequences later.

Also fixed the bug in question.
