Hmm? I'm using Win98 (Japanese), Win2K (Japanese), and
FreeBSD-current on vmware 2.0 with linux emulator of yesterday's

VMWare 2.0R broken - linux ioctl(13, 1260, *) not implemented
A missing (not implemented) linux ioctl is breaking VMWare 2.0 -
linux: 'ioctl' fd=13, cmd=1260 ('^R',96) not implemented
After rummaging around in the 2.3 kernel, I found the following in
`linux/include/linux/fs.h':
/* the read-only stuff doesn't really belong here, but any other place is
probably as bad and I don't want to create yet another include file. */
#define BLKROSET _IO(0x12,93) /* set device read-only (0 = read-write) */
#define BLKROGET _IO(0x12,94) /* get read-only status (0 = read_write) */
#define BLKRRPART _IO(0x12,95) /* re-read partition table */
#define BLKGETSIZE _IO(0x12,96) /* return device size */
#define BLKFLSBUF _IO(0x12,97) /* flush buffer cache */
#define BLKRASET _IO(0x12,98) /* Set read ahead for block device */
#define BLKRAGET _IO(0x12,99) /* get current read ahead setting */
#define BLKFRASET _IO(0x12,100)/* set filesystem (mm/filemap.c) read-ahead */
#define BLKFRAGET _IO(0x12,101)/* get filesystem (mm/filemap.c) read-ahead */
#define BLKSECTSET _IO(0x12,102)/* set max sectors per request (ll_rw_blk.c) */
#define BLKSECTGET _IO(0x12,103)/* get max sectors per request (ll_rw_blk.c) */
#define BLKSSZGET _IO(0x12,104)/* get block device sector size */
So it looks like BLKGETSIZE is the missing ioctl.
I'm not sure how to fix this, because well, we don't have block devices,
the ATA driver doesn't support ioctls _or_ have a useful psize attribute
in its cdevsw struct.
I naively thought I could use fstat() then devsw() to map the file
descriptor to a device, and then interrogate the device's psize. But that
goofy attempt just resulted in a kernel panic. :) Please don't dis me on
how stupid that was - instead tell me what I should do :)
Seriously though, any help y'all could provide would be greatly
appreciated. :)
Andrew.
