diff packages/io/disk/current/ChangeLog @ 2300:654c837cc618
* include/disk.h (DISK_CHANNEL): No need for extra _part_dev
slot intended for entire disk's own devtab.
* src/disk.c (disk_lookup): Just access pdevs_dev directly
with no adjusted offset.
(disk_init): No longer set entry 0 from device devtab.
It's unnecessary.
* include/disk.h: Merge eCosCentric CVS with public eCos CVS.
This merges (and therefore changes) the API. ChangeLog
entries have been incorporated in the correct places below.
* include/diskio.h: Also merged.
* cdl/io_disk.cdl: Also merged.
* src/disk.c: Also merged.
* src/disk.c (read_partition): Switched to favour LBA partition
information in partition tables. This also means we don't now rely
on the driver reporting a correct CHS size for the disk.
(disk_bread, disk_bwrite): API changed to take length in sectors
rather than bytes. Also call hardware driver to transfer in
(up to) max_transfer sized chunks, rather than a sector at a
time. Call in to driver now made with DSR lock claimed, to avoid a
race condition between the DSR and the calling thread.
(disk_get_config): Added phys_block_size to channel info.
* include/diskio.h (struct cyg_disk_identify_t): Added
phys_block_size and max_transfer fields. These must be filled in
by the driver.
* include/disk.h (DISK_CHANNEL_INIT): New macro. Allows a
DISK_CHANNEL to be defined dynamically.
* src/disk.c (disk_bread, disk_bwrite): Made calls to
cyg_thread_yield() dependent on presence ok kernel.
* src/disk.c (disk_bwrite): Uncomment the cyg_thread_yield() at
the end to prevent thread starvation between threads at the same
priority.
(disk_bread): Ditto.
* src/disk.c (read_partition): Changed to account for very large
disks which report bogus CHS geometry. We can only use the LBA
partition parameters in such disks.
(disk_set_config): Added some extra debug output.
* src/disk.c:
Various changes to support disconnect/reconnect of changeable
media.
* include/diskio.h: Added mount counter to disk_info structure.
* include/disk.h: Changed disk_disconnected() function to take a
pointer to a struct disk_channel rather than a struct
cyg_devtab_entry. Added mount count to disk_channel structure.
Moved include of diskio.h to end to fix declaration problems.
* src/disk.c: Fixed bug in write routine where controller result
field was not being initialized. Added signals on controller queue
condition variable after setting controller busy flag to false.
* include/disk.h: Made controller result and busy fields
volatile. Just in case.
* include/disk.h:
* src/disk.c:
Many changes. Added additional disk_controller data structure to
better reflect hardware structure. Added support for serialization
of multithreaded accesses to a single controller. Added support
for asynchronous, interrupt driven, IO operations. Various
tidies.
