view host/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.

2003-02-12 Bart Veer <bartv@ecoscentric.com> * Makefile.in: Regenerate after acinclude.m4 update 2002-08-03 Bart Veer <bartv@ecoscentric.com> * acinclude.m4, configure.in, Makefile.am: Rework host-side autoconf support 2001-10-15 Julian Smart <julians@redhat.com> * Mounts /ecos-x now, not /x * Fixed invocation of 'mount' when about to build 2001-07-26 Julian Smart <julians@redhat.com> * Only use Registry functions if building a GUI Configtool. * ecosconfig.exe doesn't now get built when building the GUI Configtool. 2001-07-09 Julian Smart <julians@redhat.com> * Fixed (I hope) a long-term bug in both versions of the Configtool, whereby conflicts involving bool-data values weren't resolved. 2001-06-18 Julian Smart <julians@redhat.com> * Added possible fix for Tcl crash bug under Windows 9x, by using the wxWindows Mkdir function instead of Tcl's mkdir. 2001-06-04 Julian Smart <julians@redhat.com> * Changed cygpath in build.cxx to use /cygdrive notation, checking in the registry first in case the user has customized the /cygdrive mount point. 2001-05-23 Julian Smart <julians@redhat.com> * Added Srdjan Sobajic's most excellent host/README improvements, and listed the directories more clearly with a brief reference to the new Configtool and its own readme. 2001-05-16 Bart Veer <bartv@redhat.com> * acinclude.m4 : Update compiler flag handling with g++ to use -O0 rather than -O2. The extra run-time performance is not worth the build overheads. Also sort out the Tcl macro for VC++ builds. * configure.in : clean up some old cruft aclocal.m4, configure, Makefile.in: regenerate 2001-01-29 Andreas Schuldei <andreas@schuldei.org> * acinclude.m4 (CYG_AC_PATH_TCL): Simplify Tcl installation searching 2000-10-23 Jesper Skov <jskov@redhat.com> * configure: Disable ser_filter magic for now - properly this time! * configure.in: Ditto. 2000-10-17 Jesper Skov <jskov@redhat.com> * configure: Disable ser_filter magic for now. * configure.in: Ditto. 2000-09-15 Jesper Skov <jskov@redhat.com> * Makefile.in: Added ser_filter rules. * configure: Ditto. * configure.in: Ditto. 2000-09-12 Bart Veer <bartv@redhat.com> * README Clarify which configure script should be used. 2000-08-18 Bart Veer <bartv@redhat.com> * configure.in: Allow cross-compilation * Makefile.in, configure: Regenerate 2000-03-13 John Dallway <jld@cygnus.co.uk> * README: Mention use of the short form of the path to the configure script under Windows. 2000-03-12 Bart Veer <bartv@redhat.com> * acinclude.m4, and lots of other files: Change the CYG_AC_PATH_TCL macro to use tclConfig.sh, make appropriate adjustments elsewhere. Also, add dependencies such that the commands now depend on the libraries. 2000-03-08 Bart Veer <bartv@redhat.com> * README: Updated. * configure.in (ECOS_DIRS): Use the infrastructure and Tcl macros at the toplevel, so that configure --help gives the right information. * configure.in (ECOS_DIRS): Look for the file tools/ecostest/common/configure, rather than just the directory. 2000-03-01 Bart Veer <bartv@redhat.com> * Create toplevel ChangeLog for the eCos host-side. //####COPYRIGHTBEGIN#### // // ---------------------------------------------------------------------------- // Copyright (C) 2000, 2001 Red Hat, Inc. // // This file is part of the eCos host tools. // // This program is free software; you can redistribute it and/or modify it // under the terms of the GNU General Public License as published by the Free // Software Foundation; either version 2 of the License, or (at your option) // any later version. // // This program is distributed in the hope that it will be useful, but WITHOUT // ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or // FITNESS FOR A PARTICULAR PURPOSE.
