This change intends to run the whole network stack in softint context
(or normal LWP), not hardware interrupt context. Note that the work is
still incomplete by this change; to that end, we also have to softint-ify
if_link_state_change (and bpf) which can still run in hardware interrupt.
This change softint-ifies at ifp->if_input that is called from
each device driver (and ieee80211_input) to ensure Layer 2 runs
in softint (e.g., ether_input and bridge_input). To this end,
we provide a framework (called percpuq) that utlizes softint(9)
and percpu ifqueues. With this patch, rxintr of most drivers just
queues received packets and schedules a softint, and the softint
dequeues packets and does rest packet processing.
To minimize changes to each driver, percpuq is allocated in struct
ifnet for now and that is initialized by default (in if_attach).
We probably have to move percpuq to softc of each driver, but it's
future work. At this point, only wm(4) has percpuq in its softc
as a reference implementation.

in the thread at tech-kern@ and tech-net@:

Thank you very much!
graphics cards will follow, when adding wscons support to them.
I didn't manage to make the "wskbd" protocol the default in the X server,
so you have to provide a small xorg.conf with Option "Protocol" "wskbd".
The standard protocol will not work as the Amiga wskbd cannot be switched
into raw mode and has no AT-scancode translation in the kernel.
On the positive side, wskbd also works with national keymaps under X.
The graphics modes can still be defined via grfconfig(8). Xorg's wsfb
driver uses the current grf video mode, which is usually mode #1.
All resolutions and depths seem to work (tested on CV64).
- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific
Due to limitations by the current pmap implementation our virtual address
space is limited to 512MB. A MAXDSIZ of 416MB would leave only a little bit
more than 30MB for shared objects and heap allocations, so 224MB seems like
a good compromise.
${MD_OBJS}.
${MD_OBJS} should be used only for objects that must be linked first (i.e.,
start code). Objects have to be compiled following common compile rules,
and have to be generated into common places (i.e., top of kernel build
directory).
${MD_LIBS} defines libraries that are built by separate makefiles, under
separate directories. `Makefile.kern.inc' doesn't know intermediate library
objects.
config(1)/config(5) can't handle module dependency correctly at this
moment.
(This is another proof that shared file definition (`file xxx.c a|b')
is a bad idea.)

after a discussion on port-m68k. I tested them on several Amiga models
and they seem to work fine.
This gives us the maximum virtual memory space for a process under the
current 512MB pmap limitation.
Also bump VM_KERNEL_PT_PAGES to allow up to 2 GB RAM.
altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate
This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr
Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)
there are two methods for a Gayle PCMCIA soft-reset.
pccard_attach() only implemented a method with works on A600 and some
older (?) A1200 models. I added the second method as well, to make the
reset work in any case. Tested on the latest A1200 model, which failed before.
