assigned by RISCOS Ltd (and were assigned by Acorn) to be unique across all
manufacturers. This means that associating each one with a manufacturer (and
checking the manufacturer when attaching) is bogus. Thus, we don't do that
any more.
This should have the pleasant side-effect of getting APDL IDE interfaces
working, since they're just ICS ones with a different manufacturer ID.
into kernel_object where this was missing.
(important here because VM_MIN_KERNEL_ADDRESS != 0)
-add some diagnostics
-eliminate some differences to other Utah derived pmaps
into kernel_object where this was missing.
This is a no-op on ports where VM_MIN_KERNEL_ADDRESS==0, ie all but
cesfic.

successfully emulates a few test program that use poll semaphores,
including the attach-to-file-descriptor-and-select feature.
There are a few issues:
1) at least one ioctl need to set retval. We handle this in irix_sys_ioctl()
by replacing the data argument by a pointer to a strucutre in the stackgap
that carries the real data and retval. The underlying ioctl methods can
therefore retreive both data and retval.
2) usemaclone is a cloning device: each time it is open, it creates a new
context, and ioctl operation on each open file descriptor will lead to
different behavior. This functionnality is available in NetBSD through the
devvp branch. This first implementation does not use devvp yet, but this
should be done later. Currently, we create a new vnode, and we provide our
own vnode operations. Some operation are applied to the cloned vnode, others
are applied to the original vnode. The v_data field is used to hold a
reference to the original vnode so that we can work on it.
3) at least the setattr vnode operation needs some customisation: IRIX
libc relies on the fact that fchmod on /dev/usema will return 0 in case
of failure.
intvid didn't find the frame buffer on his PB 170 in NetBSD 1.5. This is
because the PowerBook 140/145+145B/170 entries in intvid_info[] were
entered into the table directly from the corresponding hardware tech
notes. Unfortunately, the actual frame buffer is mapped at an offset
of 32 KB from the base of the region (at least when in 32-bit mode).
Since all 4 of these systems have identical video configurations, I'm
updating the rest to match.
PowerPC and provides a PCI-host bridge, interrupt controller, two com ports,
two IIC ports, a timer, and a DRAM controller.
The driver supports PCI, interrupts and com ports.

This fixes the endless loop when reading directories on NFS, though
applications won't see all directory entries due to different problem.

boot loader image. Installboot can modify the default command in the
first-stage bootblocks, which will have no effect. Copy the default command
from the first-stage bootblock into the second-stage bootloader so modifying
the commandline with installboot actually works again.
which are IIcx and IIx machines with not much RAM, respectively.
The PUMA config is configured somewhat optimally for one of Allen's

to use a pc-relative jump. Which is definitely not what is needed in the
relocation code!
This is new in the current assembler apparantly. None of the kernels build
after my latest upgrade were able to boot... What else is lurking!
lst_ino to __lst_ino and lst_ino64 to lst_ino, and define
LINUX_STAT64_HAS_BROKEN_ST_INO. Only assign __lst_ino if this define
is present.
This fixes compile on powerpc archs, and hence port-powerpc/16893.
- don't MALLOC() with M_WAITOK in the spl block.
move the allocation before splnet().
- when we reset vt of a class, reset the runtime service curve as well.
- don't use max() to compare 64 bit values.
pci-pci bridge (and thus needs its interrupts "swizzled").
Formerly, pci_probe_device() assumed pci busses other than bus zero
were bridged; however, much recent x86 hardware supports multiple
primary pci busses differently -- there is a system-wide bus numbering
scheme. Now, we instead look at the (newly introduced) sc_bridgetag
value in the parent bus to figure out if there's a ppb or equivalent
in the way.
This fixed at least one case where the i386 MP branch gets interrupt
mapping wrong.
deal with such xfers, and can wedge the system with some controllers.
It's a bug to request such xfers for ATAPI, but as the request may come
from userland we have to protect against it.
Restore the reset thread, to make resetting the interface possible while
not blocking interrupts.
Make sure to throw away garbage input while the reset thread is at work
(by setting sc_enabled a bit later).
Issue a PMS_RESET command when resetting to address PR 16788.
to check if we get a RQCS_DATA_UNDERRUN - if we're an FC card, we may
not have RQCS_RU set- if it isn't set, we just lost a DATA XFR IU in the
middle of the exchange. In this case, we have to bomb out the whole xfer.
We had been getting silent data corruption before.
- setup a 32KB (+32byte) stack, instead of 4KB stack
- cache flush: use _start instead of 0x4000, and flush 2k instead of 1k
Features (by me):
- implement:
OF_write() (and grab "stdout" from "/chosen")
putstrn(s,n) using OF_write(); write string s of n bytes long
putstr(s); write fixed-sized string s
putc(c); write char c
- add some useful messages which output the status of loading the
stage 2 bootstrap (which is usually ofwboot)
This code now works on Bill's Beige G3!
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.
for a device into two functions:
* pci_probe_device() actually probes/attaches the device specified
by the provide pcitag_t.
* pci_enumerate_bus() enumerates the bus, and calls pci_probe_device()
for each device on the bus. A pci_enumerate_bus_generic() is provided
which implements the old method of doing this: If something found at
dev0/func0, determine number of functions and probe each one.
Machine-dependent code will be able to specify the bus enumeration
routine in the future.
some MI PCI code that uses it, and soon there will be more. (The rationale
for not making it available previously was that it could be mis-used, but
that's true of a lot of things.)
- unify sparc_bbinfo (1064 bytes, with 256 block entries)
and sun68k_bbinfo (296 byte, with 64 block entries)
into shared_bbinfo (512 bytes, with 118 block entries),
which will be also shared by future bbinfo-using platforms
(including macppc)
- add datestamp to *_BBINFO_MAGIC strings, to prevent installboot vs
bootxx version skew.
- add macppc support
*/bootxx.c:
- migrate to new shared_bbinfo structure
installboot:
- add macppc support (still needs applepartmap support and testing)
- improve and add some more warnings & errors to installboot
- implement shared_bbinfo_clearboot() and shared_bbinfo_setboot(), which
perform the majority of the work for bbinfo-using back-ends
(rather than replicating that across multiple back-ends).
Fix receiver lockups. When writing the RX Kick register, we need back up
on descriptor since we advanced one in the for loop. That will be the
last descriptor we haven't processed which is what we should write.
I found while making sure there weren't any new ones.
* Make the write clusters keep track of the buffers whose blocks they contain.
This should make it possible to (1) write clusters using a page mapping
instead of malloc, if desired, and (2) schedule blocks for rewriting
(somewhere else) if a write error occurs. Code is present to use
pagemove() to construct the clusters but that is untested and will go away
anyway in favor of page mapping.
* DEBUG now keeps a log of Ifile writes, so that any lingering instances of
the "dirty bufs" problem can be properly debugged.
* Keep track of whether the Ifile has been dirtied by various routines that
can be called by lfs_segwrite, and loop on that until it is clean, for
a checkpoint. Checkpoints need to be squeaky clean.
* Warn the user (once) if the Ifile grows larger than is reasonable for their
buffer cache. Both lfs_mountfs and lfs_unmount check since the Ifile can
grow.
* If an inode is not found in a disk block, try rereading the block, under
the assumption that the block was copied to a cluster and then freed.
* Protect WRITEINPROG() with splbio() to fix a hang in lfs_update.
operation if more than one LIST_REMOVE happens on interrupt, so both the test
for VONWORKLIST and the LIST_REMOVE(vp, v_synclist) need to be in splbio().
Also add correct locking when freeing pages in pmap_destroy (fix from potr)
This now means that arm32 kernels can be built with LOCKDEBUG enabled. (only tested on cats though)
DHCP/Bootp is tried before bootparams in the MI nfs mountroot code.
- Change the order in boot.net from "bootparams then bootp" to
"bootp then bootparams", to be consistent with the MI nfs mountroot code.
(Consistency with other NetBSD ports is good, and things still work
for sites that run bootparams but not dhcp/bootp, although I'd argue that
dhcp/bootp is much easier to setup and manage and is easier to debug
than our rpc.bootparamd...)
Per discussion with Paul Kranenburg and Matt Green.
eliminate the kthread now that it's not necessary, and use callout instead.
This seems to fix the X mouse freeze problem.
