- Another lose is that you need to manually edit the compiler XML to add
all the kernel options because cov-configure barfs because it tries to
test the compilation environment thinking that we are userland even
when options like -ffreestanding are present.
convert several raidframe ioctls to be bitsize idempotent so that
they work the same in 32 and 64 bit worlds, allowing netbsd32 to
configure and query raid properly. remove useless 'row' in a few
places. add COMPAT_80 and put the old ioctls there.
raidframeio.h:
RAIDFRAME_TEST_ACC
- remove, unused
RAIDFRAME_GET_COMPONENT_LABEL
- convert to label not pointer to label
RAIDFRAME_CHECK_RECON_STATUS_EXT
RAIDFRAME_CHECK_PARITYREWRITE_STATUS_EXT
RAIDFRAME_CHECK_COPYBACK_STATUS_EXT
- convert to progress info not pointer to info
RAIDFRAME_GET_INFO
- version entirely.
raidframevar.h:
- rf_recon_req{} has row, flags and raidPtr removed (they're
not a useful part of this interface.)
- RF_Config_s{} and RF_DeviceConfig_s{} have numRow/rows removed.
- RF_RaidDisk_s{} is re-ordered slightly to fix alignment
padding - the actual data was already OK.
- InstallSpareTable() loses row argument
rf_compat32.c has code for RF_Config_s{} in 32 bit mode, used
by RAIDFRAME_CONFIGURE and RAIDFRAME_GET_INFO32.
rf_compat80.c has code for rf_recon_req{}, RF_RaidDisk_s{} and
RF_DeviceConfig_s{} to handle RAIDFRAME_FAIL_DISK,
RAIDFRAME_GET_COMPONENT_LABEL, RAIDFRAME_CHECK_RECON_STATUS_EXT,
RAIDFRAME_CHECK_PARITYREWRITE_STATUS_EXT,
RAIDFRAME_CHECK_COPYBACK_STATUS_EXT, RAIDFRAME_GET_INFO.
move several of the per-ioctl code blocks into separate functions.
add rf_recon_req_internal{} to replace old usage of global
rf_recon_req{} that had unused void * in the structure, ruining
it's 32/64 bit ABI.
add missing case for RAIDFRAME_GET_INFO50.
adjust raid tests to use the new .conf format, and add a case to
test the old method as well.
raidctl:
deal with lack of 'row' members in a couple of places.
fail request no longer takes row.
handle "START array" sections with just "numCol numSpare", ie
no "numRow" specified. for now, generate old-style configuration
but update raidctl.8 to specify the new style (keeping reference
to the old style.)
note that: RF_ComponentLabel_s::{row,num_rows} and
RF_SingleComponent_s::row are obsolete but not removed yet.
the compat functions (not really controlled by COMPAT_NETBSD, but for the
principle).
Makes it possible to load compat_linux.kmod from the filesystem without
any COMPAT_* option compiled (but COMPAT_NETBSD).
with a pci front-end.
The pci front-end is tied to ACPI and Intel-specific, so it's in arch/x86/pci
and not dev/pci.
Core driver from OpenBSD, PCI front-end by me.
and i2c.
dev/usb/ukbdmap.c is renamed to dev/hid/hidkbdmap.c
dev/usb/hid.[ch] moved to dev/hid/
usage pages moved from dev/usb/usbhid.h moved to dev/hid/hid.h,
and updated with OpenBSD entries.
bus-independant code moved from dev/usb/ums.c to dev/hid/hidms.c
(the same should be done for keyboard and touchpad drivers)
Needed for the upcoming HID over I2C support, proposed on tech-kern@
on Dec, 1.
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.
removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.
Works for platforms without pcppi - can work with spkr at audio and spkr
at pcppi.
To use add the following to your kernel config:
wsbell* at spkr? console?
Ok pgoyette@.
CAN stands for Controller Area Network, a broadcast network used
in automation and automotive fields. For example, the NMEA2000 standard
developped for marine devices uses a CAN network as the link layer.
This is an implementation of the linux socketcan API:
https://www.kernel.org/doc/Documentation/networking/can.txt
you can also see can(4).
This adds a new socket family (AF_CAN) and protocol (PF_CAN),
as well as the canconfig(8) utility, used to set timing parameter of
CAN hardware. Also inclued is a driver for the CAN controller
found in the allwinner A20 SoC (I tested it with an Olimex lime2 board,
connected with PIC18-based CAN devices).
There is also the canloop(4) pseudo-device, which allows to use
the socketcan API without CAN hardware.
At this time the CANFD part of the linux socketcan API is not implemented.
Error frames are not implemented either. But I could get the cansend and
canreceive utilities from the canutils package to build and run with minimal
changes. tcpudmp(8) can also be used to record frames, which can be
decoded with etherreal.
1 - ptrace(2) syscall for native emulation
2 - common ptrace(2) syscall code (shared with compat_netbsd32)
3 - support routines that are shared with PROCFS and/or KTRACE
* Add module glue for #1 and #2. Both modules will be built-in to the
kernel if "options PTRACE" is included in the config file (this is
the default, defined in sys/conf/std).
* Mark the ptrace(2) syscall as modular in syscalls.master (generated
files will be committed shortly).
* Conditionalize all remaining portions of PTRACE code on a new kernel
option PTRACE_HOOKS.
XXX Instead of PROCFS depending on 'options PTRACE', we should probably
just add a procfs attribute to the sys/kern/sys_process.c file's
entry in files.kern, and add PROCFS to the "#if defineds" for
process_domem(). It's really confusing to have two different ways
of requiring this file.
Without this, an attempt to build a kernel with COMPAT_LINUX32 but without
COMPAT_NETBSD32 will fail during the execution of genassym, and the error
messages are not very helpful.
With this change, config(1) will automatically (and silently) select/add
COMPAT_NETBSD32 to the configuration. It might be better if config(1)
were to issue an appropriate diagnostic, but that is a change for some
future day.
it's not a 16750 either. Like the 16750 it has the IIR_BUSY interrupt,
which is triggered when writing to LCR while the chip
can't accept it. But unlike the 16750, it has a specific register,
HALT, to allow writing to the LCR and divisor registers, and then
commit the changes.
Tested on an A20 SoC, changing the baud rate while keeping the
tty device open and incoming data.
because twe is already using 332
- clarify that new MI devices should go to this file
instead of majors.{ws,usb,std,tty,storage}
- fix major number conflict about hdmicec vs tty
OKed by matt@
the expression "previously not MI" is suggested by matt@ too.
sys/external/common so that they can be used by others.
LGTM from riastradh@
These should really live outside sys/external, but that can be decided
later
1. use += to add to DEPS
2. move inclusion of rules mk. files before the rules are defined
so that variables are set.
Now we get on amd64:
mkdep: ignoring acpi_wakeup_low.d: No such file or directory
mkdep: ignoring amd64func.d: No such file or directory
mkdep: ignoring busfunc.d: No such file or directory
mkdep: ignoring copy.d: No such file or directory
mkdep: ignoring cpu_in_cksum.d: No such file or directory
mkdep: ignoring cpufunc.d: No such file or directory
because there are no rules to generate those, but it is harmless.
ufs/xxx file systems depend on the vfs attribute, it is not required
that any file system actually be built-in to the kernel. (At least
on some architectures, file system modules can be loaded at boot
time.)
sysctl data belongs with the module code. Move it from kern/init_sysctl.c
to kern/uipc_sem.c
While here, add a new sysctl variable kern.posix.semcnt (current count of
semaphores) to complement the existing kern.posix.semmax (maximum number
of semaphores).
Use `.if !commands(xxx)' to check if `xxx' has a defined, overriden rule,
instead of `.if !targets(xxx)'. The latter evaluates as true even when `xxx'
has an empty rule to define a dependency.
used by hpcmips's NULLCONF, which doesn't even build for other causes.
If some source doen't build and needs a workaround, that should be deal with
by modifying per-file ${CC} options (e.g. COPTS.foo.c+=-fno-xxx). Let's not
use DEFWARNINGS any longer.
${NORMAL_S} respectively. Use the .c rule to build devsw.c, ioconf.c, and
param.c. Other .c/.S files have explicit rules in the generated `Makefile',
and unaffected.
Premature design and its build rule bloats Makefile.kern.inc. There are
other ways like MEMORY_DISK_DYNAMIC.
(When kernel will be built as relocatable, embedding binary data will be much
easier, and md(4), splash(4), and ksyms(4) will all benefit.)
Define MAXUSERS in opt_param.h and include it from sys/param.h, for more
accurate dependency. Don't define -DMAXUSERS and add it to ${CPPFLAGS}.
config(5)'s "maxusers" syntax doesn't change.
(The version just before revert was OK, but I had something bad in my obj
dirs.)
o Explicitly add dependency of `<kernel>' on `<kernel>.ldscript', instead of
relying on ${SYSTEM_DEP}, which is evaluated much earlier than
`sys/conf/Makefile.kern.inc' is included, to avoid evaluation ordering
problems.
o Print a message when creating a `<kernel>.ldscript'.
o Trim empty lines in `<kernel>.ldscript'.
Thus some constants (PAGE_SIZE, COHERENCY_UNIT, ...) can be replaced in linker
scripts without setting unnecessary temporary symbols, or doing ugly sed(1)
hacks. No headers are included yet.
o Depend on ${SYSTEM_OBJ} instead of ${SYSTEM_DEP}. The latter is obviously
meant for kernels.
o Depend on Makefile instead of ${SYSTEM_SWAP_DEP}, which has existed since
Rev. 1.1, but seems not used now. Makefile is a file that must be updated
after every config(1) run. This is simpler than dependency on swap<kernel>.c.
the subsystem, not "Verifiedexec".
The revisions of kern_verifiedexec.c are now in Attic/.
No change between kern_verifiedexec.c and kern_veriexec.c.
Also, update the man page accordingly.
Okayed by christos@ and blymn@ some months ago.
o Introduce a new selection directive "select" to select an attribute (as a
module) and its dependencies.
o Support "no select" too.
o Stop abusing "options" to select an attribute.
o Bump config(1) version.
config(1) still keeps backward-compatibility; it is more permissive than
before. The tree, however, needs the updated config(1), mainly to strictly
define attribute ("module") ownership and dependencies.
The arcofi(4) is a driver for the HP "Audio1" device
(Siemens PSB 2160 "ARCOFI" phone quality audio chip)
found on the HP9000/425e and HP9000/{705,710,745,747} models
(but only hp300 attachment is ported for now).
The chip supports 8-bit mono 8kHz U-law, A-law and
16-bit mono slinear_be formats.
The old HP9000/425e playing tunes with this new arcofi(4) audio driver
was also demonstrated at Open Source Conference 2014 Shimane.
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.
If the BUILDINFO environment variable is set, then interpret it as
a string with embedded C-style escapes and store it in a new
buildinfo variable in the emitted vers.c file.
Also centralise the awk code for converting a multi-line string
to C source code.
as found in several SoCs.
Only host mode is supported, good enough for umass (USB keys), kubd and ums,
and USB2 hubs.
It fails to properly talk to USB/serial adapters at this time.
- Replace ipintrq and ip6intrq with the pktqueue mechanism.
- Eliminate kernel-lock from ipintr() and ip6intr().
- Some preparation work to push softnet_lock out of ipintr().
Discussed on tech-net.
The four modules are apple_smc for the core functions, apple_smc_acpi
for attachment at acpi, and apple_smc_fan & apple_smc_temp for stuff
on the SMC.
Seems like there's a lot more bookkeeping necessary to maintain
children of an applesmc device implemented by loadable modules.
Maybe there's a better way I just haven't figured out yet.
Device interface derived by reading the Linux driver source code and
<http:///www.parhelia.ch/blog/statics/k3_keys.html> as of 2012-12-05.
Includes support for attaching fan and temperature sensors to sysmon.
No accelerometer yet.
Compile-tested only, based on some run-testing of experiments from
userland. Module attachment is not quite finished, so it won't work
yet.
Otherwise, we will get the error when building a kernel with -V MKDTRACE:
