cdl/io_disk.cdl: Use CYGPKG_IO as the parent.

|
|
|

|
|
* include/disk.h (DISK_CHANNEL): No need for extra _part_dev
|
| 8 |
|
|
slot intended for entire disk's own devtab.
|
| 9 |
|
|
|
| 10 |
|
|
* src/disk.c (disk_lookup): Just access pdevs_dev directly
|
| 11 |
|
|
with no adjusted offset.
|
| 12 |
|
|
(disk_init): No longer set entry 0 from device devtab.
|
| 13 |
|
|
It's unnecessary.

|
| 16 |
|
|
|
| 17 |
|
|
* include/disk.h: Merge eCosCentric CVS with public eCos CVS.
|
| 18 |
|
|
This merges (and therefore changes) the API. ChangeLog
|
| 19 |
|
|
entries have been incorporated in the correct places below.
|
| 20 |
|
|
* include/diskio.h: Also merged.
|
| 21 |
|
|
* cdl/io_disk.cdl: Also merged.
|
| 22 |
|
|
* src/disk.c: Also merged.
|

|
| 25 |
|
|
|
| 26 |
|
|
* cdl/io_disk.cdl: Made debugging CDL controlled.
|
| 27 |
|
|
* src/disk.c: Added support to allow non-CHS disk devices to
|
| 28 |
|
|
use LBA information in MBR.
|
| 29 |
|
|
|
| 30 |
|
|
2006-02-03 Nick Garnett
|
| 31 |
|
|
|
| 32 |
|
|
* src/disk.c (read_partition): Switched to favour LBA partition
|
| 33 |
|
|
information in partition tables. This also means we don't now rely
|
| 34 |
|
|
on the driver reporting a correct CHS size for the disk.
|
| 35 |
|
|
(disk_bread, disk_bwrite): API changed to take length in sectors
|
| 36 |
|
|
rather than bytes. Also call hardware driver to transfer in
|
| 37 |
|
|
(up to) max_transfer sized chunks, rather than a sector at a
|
| 38 |
|
|
time. Call in to driver now made with DSR lock claimed, to avoid a
|
| 39 |
|
|
race condition between the DSR and the calling thread.
|
| 40 |
|
|
(disk_get_config): Added phys_block_size to channel info.
|
| 41 |
|
|
|
| 42 |
|
|
* include/diskio.h (struct cyg_disk_identify_t): Added
|
| 43 |
|
|
phys_block_size and max_transfer fields. These must be filled in
|
| 44 |
|
|
by the driver.
|
| 45 |
|
|
|
| 46 |
|
|
2005-12-12 Jonathan Larmour
|
| 47 |
|
|
|
| 48 |
|
|
* include/disk.h (DISK_CHANNEL_INIT): New macro. Allows a
|
| 49 |
|
|
DISK_CHANNEL to be defined dynamically.
|
| 50 |
|
|
|
| 51 |
|
|
2005-12-02 Andrew Lunn
|
| 52 |
|
|
|
| 53 |
|
|
* src/disk.c: Add comments that bread/bwrite take the position and
|
| 54 |
|
|
len in terms of blocks, not bytes.
|
| 55 |
|
|
|
| 56 |
|
|
2005-10-11 Nick Garnett
|
| 57 |
|
|
|
| 58 |
|
|
* src/disk.c (disk_bread, disk_bwrite): Made calls to
|
| 59 |
|
|
cyg_thread_yield() dependent on presence ok kernel.
|
| 60 |
|
|
|
| 61 |
|
|
2005-06-01 Jonathan Larmour
|
| 62 |
|
|
|
| 63 |
|
|
* src/disk.c (disk_bwrite): Uncomment the cyg_thread_yield() at
|
| 64 |
|
|
the end to prevent thread starvation between threads at the same
|
| 65 |
|
|
priority.
|
| 66 |
|
|
(disk_bread): Ditto.
|
| 67 |
|
|
|

|
|
2004-07-21 Nick Garnett
|
| 69 |
|
|
|
| 70 |
|
|
* src/disk.c (read_partition): Changed to account for very large
|
| 71 |
|
|
disks which report bogus CHS geometry. We can only use the LBA
|
| 72 |
|
|
partition parameters in such disks.
|
| 73 |
|
|
(disk_set_config): Added some extra debug output.
|
| 74 |

|
| 76 |
|
|
|
| 77 |
|
|
* src/disk.c:
|
| 78 |
|
|
* include/disk.h:
|
| 79 |
|
|
* include/diskio.h:
|
| 80 |
|
|
Use predefined arrays for partition devices and info
|
| 81 |
|
|
radher than malloc. Extended DISK_CHANNEL macro to
|
| 82 |
|
|
support defining maximum number of partitions.
|
| 83 |
|
|
|
| 84 |
|
|
2004-04-15 Nick Garnett
|
| 85 |
|
|
|
| 86 |
|
|
* src/disk.c:
|
| 87 |
|
|
Various changes to support disconnect/reconnect of changeable
|
| 88 |
|
|
media.
|
| 89 |
|
|
|
| 90 |
|
|
* include/diskio.h: Added mount counter to disk_info structure.
|
| 91 |
|
|
|
| 92 |
|
|
* include/disk.h: Changed disk_disconnected() function to take a
|
| 93 |
|
|
pointer to a struct disk_channel rather than a struct
|
| 94 |
|
|
cyg_devtab_entry. Added mount count to disk_channel structure.
|
| 95 |
|
|
Moved include of diskio.h to end to fix declaration problems.
|
| 96 |
|
|
|
| 97 |

|
2004-02-04 Nick Garnett
|
| 98 |
|
|
|
| 99 |
|
|
* src/disk.c: Fixed bug in write routine where controller result
|
| 100 |
|
|
field was not being initialized. Added signals on controller queue
|
| 101 |
|
|
condition variable after setting controller busy flag to false.
|
| 102 |
|
|
|
| 103 |
|
|
* include/disk.h: Made controller result and busy fields
|
| 104 |
|
|
volatile. Just in case.
|
| 105 |
|
|
|
| 106 |
|
|

| 107 |
|
|
|
| 108 |
|
|
* include/disk.h:
|
| 109 |
|
|
* src/disk.c:
|
| 110 |
|
|
Many changes. Added additional disk_controller data structure to
|
| 111 |
|
|
better reflect hardware structure. Added support for serialization
|
| 112 |
|
|
of multithreaded accesses to a single controller. Added support
|
| 113 |
|
|
for asynchronous, interrupt driven, IO operations. Various
|
| 114 |
|
|
tidies.
|
| 115 |

|
| 117 |
|
|
|
| 118 |
|
|
* src/disk.c:
|
| 119 |
|
|
* include/disk.h: Removed block_pos arguments from
|
| 120 |
|
|
hardware driver read and write calls: it is not necessary.
|
| 121 |
|
|
|
| 122 |
|
|
* src/disk.c (read_mbr): Modified to read a complete sector from
|
| 123 |
|
|
the disk rather than pieces. Drivers should only ever see
|
| 124 |
|
|
reads/writes in multiples of 512 bytes.
|
| 125 |

|
| 127 |
|
|
|
| 128 |
|
|
* src/disk.c:
|
| 129 |
|
|
Check return code from MBR scan and set
|
| 130 |
|
|
connected flag only if there was no error.
|
| 131 |
