Add flag to enforce file I/O even when bmap/strategy would be possible.
This makes it easier to compare both modes, it also allows coherent
operation between vnd device and image file.

When backed by a sparse file limit the number of pending requests.
Should fix PR #45829: "writing to vnd on sparse file blocks on pager_map"
where the pager_map gets exhausted by requests enqueued on a vnd
device and the device worker thread blocks on putpages() needing the map.
While here always sync the underlying vnode before calling biodone().
XXX: vnd should be converted to mutex/condvar.

hannken | branches: 1.31.2; 1.31.6; 1.31.8;
Make vnd(4) work on sparse files:
- Make the strategy decision a device flag and set VNF_USE_VN_RDWR for
files known to be sparse.
- Change handle_with_rdwr() to use POSIX_FADV_NOREUSE advise to disable
read ahead and keep the size of mapped pages below 1 MByte.
No objections on tech-kern@.

actually, put the old definitions back into vndvar.h, under _KERNEL,
as netbsd32 wants access to them.

| 19-Sep-2010 |
mrg | fix the vnd_osize changes on 32 bit platforms with 64 bit alignment for
64 bit integers (eg, sparc). the problem was that the new 64 bit
element on the end was used for the offsetof() (aka size) for the old
structure, but this includes the padding required, thus the ioctl number
was set wrongly.
move all the supporting code for this inside COMPAT_50, with some renaming
to suit, and kill all the external definitions related to it.
tested on i386, amd64 and sparc.
|
| 1.27 |
| 19-Sep-2010 |
mrg | add support for COMPAT_50 ioctls. struct vnd_user has a dev_t component
which grew since netbsd 5.0 (hi christos!)
fix a few issues/problems:
- the COMPAT_30 code wasn't used since opt_compat_netbsd.h wasn't included
- move 'struct vnd_ouser' (for COMPAT_30) into vnd.c itself, and call it
'struct vnd_user30'
- same for VNDIOOCGET -> VNDIOCGET30
now 'vnconfig -l' works on -current with a netbsd-5 binary, using i386.
XXX: there is still a potential problem with the old VNDIOOCSET and
VNDIOOCCLR macros on some platforms like sparc. there is padding
between the old vnd_osize member and the new vnd_size member on
platforms that want 64 bit values 64 bit aligned, but are 32 bit
otherwise (like sparc.) 64 bit systems already end up with this
member 64 bit aligned, and should be fine.
this most likely results in the old ioctl numbers being wrong and
the code won't match/run ever (ENOTTY.)

Add compatibility for the old ioctl size.

Part of fix for PR/41873.

- rather than embedding bufq_state in driver softc,
have a pointer to the former.
- move bufq related functions from kern/subr_disk.c to kern/subr_bufq.c.
- rename method to strategy for consistency.
- move some definitions which don't need to be exposed to the rest of kernel
from sys/bufq.h to sys/bufq_impl.h.

Add full disklabel and partition support to the vnd driver, allowing much
greater flexibility in its use. Additionally, add support for "geometry
emulation". This allows the "geometry" of the "disk" to be specified
at config time, providing near-perfect emulation of disklabel-less floppies,
CD-ROMs, etc., including non-512-byte sectors. If a geometry is not
specified at config time, a default based on 1M cylinders will be used.

Runs on i386, needs work on other arch's. Main kernel routines should be
fine, but a number of the stand programs need help.
cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512
byte block devices. vnd, raidframe, and lfs need work.
Non 2**n block support is automatic for LKM's and conditional for kernels
on "options NON_PO2_BLOCKS".

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.
