NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.
eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing. eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.
NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman. Microsoft Corporation has
donated full copyright to The NetBSD Foundation.
Platform support for eMIPS is the first part of Microsoft's
contribution. The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.
LOADMODULES->NOMODULES and READBOOTCONF->NOBOOTCONF.
This way, the default value (0) wired into old bootxx_* and installed
to file systems remains valid and we avoid problems on partial updates.
whether modules are loaded and whether boot.cfg is evaluated, and
set both to "off" per default in the PXE bootloader.
Extend "installboot" to toggle the bits.
This way, pxeboot works with existing dhcp server setups (and as
described in the manpage) out of the box. Also, boot.cfg reading
involves a stat() call which is horribly inefficient with the
TFTP pseudo file system.
where sector size (disk block size) is required, instead of
DEV_BSIZE constant which means device I/O block size.
"Looks reasonable" from dholland@, and fixes tools installboot(8)
on Cygwin where DEV_BSIZE != 512 as mentioned in PR toolchain/42555.
specified using a file name on the running system, while the secondary
bootstrap is specified using a file name relative to the root of the
file systrem in which the installation is being performed.
Inspired by PR 39728 by der Mouse
the secondary boot is stored to embed them into the primary bootxx)
for ext2fs.
Currently disabled because there is no primary boot block
which supports ext2fs, but it might help someone in some day.
If specified then checks on the disks BPB are not done, and any existing BPB
is deleted.
This is needed soince newfs(8) doesn't overwrite the BPB - which is basically
the FAT superblock.
Update documentation and add an example of using bootxx_fat16.
Automatically enable writes to the 'labelsector' if necessary.
Detect and recover from problems with the write-protected 'labelsector'
stopping writes to nearby sectors when the non-raw disk device is used.
Support the installation of 512-byte pbr boot code (eg fatboot).
Verify that there is enough reserved space in the bpb (if not all zeros) to
avoid overwriting the start of FAT filesystems.
