the computer speaker when it's completely safe to power down the machine
(after the "The operating system has halted." message). This is useful for
headless machines.
The feature is only enabled if the BEEP_ONHALT option is defined (disabled by default). It can be tuned through the BEEP_ONHALT_{COUNT,PERIOD,PITCH} options.
Closes my own PR kern/18792.
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.
The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.
Define an attribute for each crypto algorithm, and use that attribute
to select the files that implement the algorithm.
* Give the "wlan" attribute a dependency on the "arc4" attribute.
* Give the "cgd" pseudo-device the "des", "blowfish", "cast128", and
"rijndael" attributes.
* Use the new attribute-as-option-dependencies feature of config(8) to
give the IPSEC_ESP option dependencies on the "des", "blowfish", "cast128",
and "rijndael" attributes.
caveats, but works quite well in a lot of MP cases, and all
UP cases that I have tested. Parts of this will hopefully be
reworked in the not-too-distant future.
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.
driver attaches where "pchb" would normally attach (it matches at a
higher match priority). The "elansc" driver currently provides support
for the watchdog timer built-in the SC520.
Thanks to Jasper Wallace for laying the ground-work for this (most
notably by providing a work-around for a watchdog-related bug in the
SC520).
8-bit pseudo color and text modes
still doesn't do anything useful
(It would be easy to attach a wsdisplay, but we have to cooperate with the
PCI or ISA attached VGA drivers. There are open issues.)
* Pull in dev/mii/files.mii from conf/files, rather than playing
the magic "files include order" dance in N machine-dependent
configuration definitions.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h
device (rather, the device that carries that attribute) also
carry one or more attributes indicating which type of controller
it might be.
This will allow systems that might have AGP, but would never have
e.g. an Intel PCI-Host bridge, to trim out code that won't be used.
This also involved updating the in-kernel DES functions to correspond
to the versions in our in-tree OpenSSL, because the des_SPtrans table
has changed; the asm code will not work with the old permutation table!
C and i386 asm code for the DES, 3DES, and Blowfish CBC modes is also
included; it is not currently built as the ESP processing in esp_core.c
splits the CBC operation and the cipher transform apart. Hopefully that
will be fixed as there is a substantial performance improvement to be had
from doing so. It will remain necessary to use the C version of the
Blowfish CBC function on some i386 machines, however, as the asm version
uses bswapl, which ony 486 and later processors have. The DES CBC code
doesn't have this problem.
Finally, change esp_core.c to use the ecb3_encrypt function instead of
calling ecb_encrypt three times; this improves performance a bit, in
particular in the asm case.
