This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
and move them in their proper places.
Move the BRI registry from layer 2 (duh!) to layer 4, so active cards
(which don't have layer 3 or layer 2 in their driver). Remove all remaining
hard coded controller and driver types. Remove any arbitrary hard coded
limits, at least those that show up in the internal API.
This fixes PR 15950.
indicating an unhandled "command". ERESTART is -1, which can lead to
confusion. ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4. No ioctl code should now return -1 anywhere. The
ioctl() system call is now properly restartable.
conf/GENERIC:
conf/files.amiga:
- Bring in wsfont definitions.
dev/grfabs_reg.h:
- Add macros for decomposing palette entries.
dev/amidisplaycc.c:
- Support for fonts, either wsfonts compiled into kernel
or runtime-loadable by ioctl. Font width still limited to 8,
height may vary.
- Limited support for mapped displays. No way to adjust display
mode. Palette setting works.
- Prettier default palette (white on black).
- Probes correctly as WSDISPLAY_TYPE_AMIGACC.
- Support for screen blanking.
Actually, this is added to the siop2_script; should we ever support another
siopng board that does connect something else to GPREG bit 4, we'll have
to move this to C code and make it optional.
OTOH, by then we'll have switched to the MI driver by then.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.
Currently this is a no-op on most platforms, so they should see no difference.
