ubix2
Revision 1.2 2005/10/12 00:13:38 reddawg
Removed
Revision 1.1.1.1 2005/09/26 17:24:44 reddawg
no message
Revision 1.4 2004/09/20 00:53:04 flameshadow
chg: UbixFS::vfs_read() now works for direct block extents
chg: UbixFS::vfs_read() returns ~0 on error, or the size read in on success
chg: UbixFS::root member is now a fileDescriptor
chg: UbixFS::vfs_init() creates a file descriptor for the root dir
chg: UbixFS::vfs_format() now sets all values in the bTreeHeader before writing
chg: UbixFS::vfs_format() sets the inode magic number
chg: device_t::read(device_t *, void *, off_t, size_t)
chg: device_t::write(device_t *, void *, off_t, size_t)
chg: vfs_abstract::vfs_read(fileDescriptor *, void *, off_t, size_t)
chg: vfs_abstract::vfs_write(fileDescriptor *, void *, off_t, size_t)
chg: ramDrive_read(device_t *dev,void *ptr,off_t offset,size_t length)
chg: ramDrive_write(device_t *dev,void *ptr,off_t offset,size_t length)
Revision 1.3 2004/09/13 15:21:26 flameshadow
add: ramdrive.h
chg: renamed device_t.size to sectors
chg: made #define for size of ramdisk
chg: calculated sectors of ramdisk and stored in the device_t struct
Revision 1.2 2004/09/11 22:05:59 flameshadow
chg: modified UbixFS::vfs_format() to properly init the device
chg: modified UbixFS::vfs_init() to verify that it's a ubixfs partition
add: added BAT blockRun in the superBlock
Revision 1.1 2004/09/11 12:43:42 flameshadow
add: device.h, types.h. Temporarily moved custom ubix typedefs to types.h
(<ubixos/types.h> supercedes this file when this code is included into
the kernel)
chg: changed dev_t to device_interface so as to not conflict with bsd/linux
definitions
chg: fixed up compiler warnings in btree.cpp
Revision 1.14 2004/08/15 00:33:02 reddawg
Wow the ide driver works again
Revision 1.13 2004/08/14 21:56:44 reddawg
Added initialized byte to the device system to make it easy to add child devices which use parent hardware.
Revision 1.12 2004/07/21 10:02:09 reddawg
devfs: renamed functions
device system: renamed functions
fdc: fixed a few potential bugs and cleaned up some unused variables
strol: fixed definition
endtask: made it print out freepage debug info
kmalloc: fixed a huge memory leak we had some unhandled descriptor insertion so some descriptors were lost
ld: fixed a pointer conversion
file: cleaned up a few unused variables
sched: broke task deletion
kprintf: fixed ogPrintf definition
Revision 1.11 2004/05/22 02:40:04 ionix
fixed typo in device.h and initialized previous in device.c :)
Revision 1.10 2004/05/22 02:34:03 ionix
Added proto
Revision 1.9 2004/05/21 15:12:17 reddawg
Cleaned up
