* Indentation issues.pfg2016-04-201-2/+1
| | | | | | Contract some lines leftover from r298310. Mea culpa.
* kernel: use our nitems() macro when it is available through param.h.pfg2016-04-191-1/+1
| | | | | | No functional change, only trivial cases are done in this sweep, Discussed in: freebsd-current
* ddb: finish converting boolean values.pfg2015-05-211-1/+1
| | | | | | | | | The replacement started at r283088 was necessarily incomplete without replacing boolean_t with bool. This also involved cleaning some type mismatches and ansifying old C function declarations. Pointed out by: bde Discussed with: bde, ian, jhb
* Build on Jeff Roberson's linker-set based dynamic per-CPU allocatorrwatson2009-07-141-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (DPCPU), as suggested by Peter Wemm, and implement a new per-virtual network stack memory allocator. Modify vnet to use the allocator instead of monolithic global container structures (vinet, ...). This change solves many binary compatibility problems associated with VIMAGE, and restores ELF symbols for virtualized global variables. Each virtualized global variable exists as a "reference copy", and also once per virtual network stack. Virtualized global variables are tagged at compile-time, placing the in a special linker set, which is loaded into a contiguous region of kernel memory. Virtualized global variables in the base kernel are linked as normal, but those in modules are copied and relocated to a reserved portion of the kernel's vnet region with the help of a the kernel linker. Virtualized global variables exist in per-vnet memory set up when the network stack instance is created, and are initialized statically from the reference copy. Run-time access occurs via an accessor macro, which converts from the current vnet and requested symbol to a per-vnet address. When "options VIMAGE" is not compiled into the kernel, normal global ELF symbols will be used instead and indirection is avoided. This change restores static initialization for network stack global variables, restores support for non-global symbols and types, eliminates the need for many subsystem constructors, eliminates large per-subsystem structures that caused many binary compatibility issues both for monitoring applications (netstat) and kernel modules, removes the per-function INIT_VNET_*() macros throughout the stack, eliminates the need for vnet_symmap ksym(2) munging, and eliminates duplicate definitions of virtualized globals under VIMAGE_GLOBALS.

* - Change the ddb paging "support" to use a variable (db_lines_per_page) tojhb2004-11-011-0/+1
| | | | | | | | | | | | | | | | | control the number of lines per page rather than a constant. The variable can be examined and changed in ddb as '$lines'. Setting the variable to 0 will effectively turn off paging. - Change db_putchar() to force out pending whitespace before outputting newlines and carriage returns so that one can rub out content on the current line via '\r \r' type strings. - Change the simple pager to rub out the --More-- prompt explicitly when the routine exits. - Add some aliases to the simple pager to make it more compatible with more(1): 'e' and 'j' do a single line. 'd' does half a page, and 'f' does a full page. MFC after: 1 month Inspired by: kris
* Mega update for the KDB framework: turn DDB into a KDB backend.marcel2004-07-101-71/+50
| | | | | | | | | | | | | | | | Most of the changes are a direct result of adding thread awareness. Typically, DDB_REGS is gone. All registers are taken from the trapframe and backtraces use the PCB based contexts. DDB_REGS was defined to be a trapframe on all platforms anyway. Thread awareness introduces the following new commands: thread X switch to thread X (where X is the TID), show threads list all threads. The backtrace code has been made more flexible so that one can create backtraces for any thread by giving the thread ID as an argument to trace. With this change, ia64 has support for breakpoints.

* This commit fixes various 64bit portability problems required fordfr1998-06-071-2/+2
| | | | | | | | | | FreeBSD/alpha. The most significant item is to change the command argument to ioctl functions from int to u_long. This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-141-1/+1
| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

| | | | | | | | | | to get the prototypes. Changed some `int's to `boolean_t's. boolean_t's are ints so they are hard to distinguish from ints. Converted function headers to old-style. ddb is written in K&R1 C except where we broke it.

* Fix up some sloppy coding practices:wollman1994-08-181-2/+1
| | | | | | | | | | | | - Delete redundant declarations. - Add -Wredundant-declarations to Makefile.i386 so they don't come back. - Delete sloppy COMMON-style declarations of uninitialized data in header files. - Add a few prototypes. - Clean up warnings resulting from the above. NB: ioconf.c will still generate a redundant-declaration warning, which is unavoidable unless somebody volunteers to make `config' smarter.
* Change all #includes to follow the current Berkeley style. Some of thesewollman1994-08-131-5/+5
| | | | | | | | | | | | | | | | | | | | | ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make
