chs | in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.
|
| 1.28 |
| 20-Aug-2015 |
christos | branches: 1.28.18;
include "ioconf.h" to get the 'void <driver>attach(int count);' prototype.
|
| 1.27 |
| 14-Dec-2014 |
chs | add a new "fo_mmap" fileops method to allow use of arbitrary uvm_objects for
mappings of file objects. move vnode-specific details of mmap()ing a vnode
from uvm_mmap() to the new vnode-specific vn_mmap(). add new uvm_mmap_dev()
and uvm_mmap_anon() convenience functions for mapping character devices
and anonymous memory, and replace all other calls to uvm_mmap() with those.
use the new fileop in drm2 so that libdrm can use mmap() to map things
like on other platforms (instead of the ioctl that we have used so far).

dholland | branches: 1.26.2; 1.26.4;
Add d_discard to all struct cdevsw instances I could find.
All have been set to "nodiscard"; some should get a real implementation.
|
| 1.25 |
| 16-Mar-2014 |
dholland | branches: 1.25.2;
Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

hubertf | branches: 1.18.2;
Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.
To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".
Thanks to martin@ for the input on testing.

| 1.17 |
| 09-Mar-2006 |

|
| 1.12 |
| 24-Feb-2003 |
atatat | branches: 1.12.2;
Cast VM_DEFAULT_ADDRESS() to a caddr_t.
|
| 1.11 |
| 20-Feb-2003 |
atatat | Introduce "top down" memory management for mmap()ed allocations. This
means that the dynamic linker gets mapped in at the top of available
user virtual memory (typically just below the stack), shared libraries
get mapped downwards from that point, and calls to mmap() that don't
specify a preferred address will get mapped in below those.
This means that the heap and the mmap()ed allocations will grow
towards each other, allowing one or the other to grow larger than
before. Previously, the heap was limited to MAXDSIZ by the placement
of the dynamic linker (and the process's rlimits) and the space
available to mmap was hobbled by this reservation.
This is currently only enabled via an *option* for the i386 platform
(though other platforms are expected to follow). Add "options
USE_TOPDOWN_VM" to your kernel config file, rerun config, and rebuild
your kernel to take advantage of this.
Note that the pmap_prefer() interface has not yet been modified to
play nicely with this, so those platforms require a bit more work
(most notably the sparc) before they can use this new memory
arrangement.
This change also introduces a VM_DEFAULT_ADDRESS() macro that picks
the appropriate default address based on the size of the allocation or
the size of the process's text segment accordingly. Several drivers
and the SYSV SHM address assignment were changed to use this instead
of each one picking their own "default".

| 1.10 |
| 23-Oct-2002 |
jdolecek | merge kqueue branch into -current
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
|
| 1.9 |
| 10-Oct-2002 |
jdolecek | replace the somewhat strange poll routine with standard nopoll() (a.k.a
seltrue())
|
| 1.8 |
| 06-Sep-2002 |
gehenna | Merge the gehenna-devsw branch into the trunk.
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.

wiz | branches: 1.7.2; 1.7.4; 1.7.8; 1.7.16;
Remove unused variable. Reported by Thilo Manske in port-mac68k/12794.
|
| 1.6 |
| 15-Mar-2001 |
chs | eliminate the KERN_* error codes in favor of the traditional E* codes.
the mapping is:
KERN_SUCCESS 0
KERN_INVALID_ADDRESS EFAULT
KERN_PROTECTION_FAILURE EACCES
KERN_NO_SPACE ENOMEM
KERN_INVALID_ARGUMENT EINVAL
KERN_FAILURE various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE ENOMEM
KERN_NOT_RECEIVER <unused>
KERN_NO_ACCESS <unused>
KERN_PAGES_LOCKED <unused>
|
| 1.5 |
| 29-Jun-2000 |
mrg | branches: 1.5.2; 1.5.4;
remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
|
| 1.4 |
| 26-Jun-2000 |
simonb | Change the kernel mmap interface so that the offset to map is an
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

scottr | branches: 1.3.2;
Make this compile with GRF_COMPAT. Problem pointed out by Hauke Fath.
|

scottr | branches: 1.2.2;
Merge wscons work onto the main development branch.
|
| 1.1 |
| 15-Nov-1999 |
scottr | branches: 1.1.2;
file grf_compat.c was initially added on branch scottr-mac68k-wscons.
|
| 1.1.2.5 |
| 20-Nov-1999 |
scottr | Clear the screen on close to emulate the behavior of legacy
grf devices.
|
| 1.1.2.4 |
| 18-Nov-1999 |
scottr | Revert 1.1.2.2; further testing shows that the problem lies elsewhere.
|
| 1.1.2.3 |
| 18-Nov-1999 |
scottr | Improved emulation of grf devices:
- sync return value for unsupported ioctls with legacy grf driver
- returning (-1) from grfioctl() is hardly appropriate; return EINVAL
when we are given an unknown ioctl (duh)
- don't add the displayable region offset in grfmmap(); apps handlj
this themselves
|
| 1.1.2.2 |
| 17-Nov-1999 |
scottr | Avoid MAP_FIXED in grfmap(); it doesn't buy us anything
with the apps that use it, and can cause some systems (e.g. the IIci)
to behave erratically.
|
| 1.1.2.1 |
| 15-Nov-1999 |
scottr | Implement a more straightforward approach to grf emulation.

bouyer | Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
