/v2_0/ChangeLog
0,0 → 1,1192
2003-02-24 Jonathan Larmour <jifl@eCosCentric.com>
 
* cdl/ser_mn10300.cdl: Remove irrelevant doc link.
 
2001-09-10 Jonathan Larmour <jlarmour@redhat.com>
 
* cdl/ser_mn10300.cdl:
Fix 234000->230400 typo.
 
2000-08-01 Jonathan Larmour <jlarmour@redhat.co.uk>
 
* src/mn10300_serial.c (mn10300_serial_set_config): Now use keys to make
more flexible.
 
2000-06-22 Hugo Tyson <hmt@cygnus.co.uk>
 
* cdl/<yournamehere>.cdl: Remove the comment on the empty
include_files directive; the tools now support this correctly.
This keeps internal include files internal.
 
2000-04-11 Hugo Tyson <hmt@cygnus.co.uk>
 
* cdl/ser_mn10300.cdl: Change the parent from CYGPKG_IO_SERIAL
(which is enabled most of the time) to CYGPKG_IO_SERIAL_DEVICES
(which is not...) thus allowing convenient control independent of
platform. Also enable all individual devices by default, now, so
that they can be enabled simply by enabling the above new parent.
 
2000-04-07 Hugo Tyson <hmt@cygnus.co.uk>
 
* ecos.db: Re-organize device packages. This is a massive change
involving deleting all the sources for serial and ethernet drivers
from where they used to live in
packages/io/serial/current/src/ARCH/PLATFORM.[ch]
packages/net/drivers/eth/PLATFORM/current/src/...
and reinstating them in
packages/devs/serial/ARCH/PLATFORM/current/src/...
packages/devs/eth/ARCH/PLATFORM/current/src/...
 
All these new packages are properly defined in ecos.db, and are
all of type "hardware" so that a "target" can grab them.
This directory layout is descriptive of the devices we have right
now, arch and platform are separate levels just to make it easier
to navigate in the filesystem and similar to the HAL structure in
the filesystem.
 
It is *not* prescriptive of future work; for example, the mythical
common highly-portable 16550 serial driver which works on many
targets would be called "devs/serial/s16550/current", or a serial
device for a particular board (cogent springs to mind) that can
work with different CPUs fitted is "devs/serial/cogent/current".
 
Changelogs have been preserved and replicated over all the new
packages, so that no history is lost.
 
The contents of individual source files are unchanged; they build
in just the same emvironment except for a very few cases where the
config file name changed in this movement.
 
Targets in ecos.db have been redefined to bring in all relevant
hardware packages including net and serial drivers (but the newly
included packages are only active if their desired parent is
available.)
The names of CDL options (and their #defines of course) stay the
same for the serial drivers, for backward compatibility.
 
* templates/*/current.ect: these have had CYGPKG_IO_SERIAL added
rather than it being in (almost) all target definitions.

Imported following changes from development branch:
1999-08-11 Nick Garnett <nickg@cygnus.co.uk>
 
* tests/serial5.c: Modified config test for boards that need a lower
speed for this test.
 
* tests/ser_test_protocol.inl: Removed 14400 baud tests for all
MN10300 variants. The MN10300 cannot currently do this speed.
 
* src/mn10300/mn10300_serial.c: Tidied up the transmit interrupt
enable/disable code to be variant specific.
 
* include/pkgconf/io_serial.h: Undid Jonathan's change, since the
same options are used for all MN10300 variants.
1999-08-10 Jonathan Larmour <jlarmour@cygnus.co.uk>
 
* include/pkgconf/io_serial.h:
Reparent CYGPKG_IO_SERIAL_MN10300 from under CYGPKG_HAL_MN10300 to
CYGPKG_HAL_MN10300_AM32_STDEVAL1 since it's stdeval1 specific
 
1999-08-04 Nick Garnett <nickg@cygnus.co.uk>
 
* tests/ser_test_protocol.inl:
Changed names of MN10300 defines tested. Added AM33 definitions.
 
* src/mn10300/mn10300_serial.c:
Modified driver to work on am33 too. This simply requires some
alternate definitions of things like register addresses and some
bits in them plus some extra parameterization of some register
values.
 
* src/PKGconf.mak:
Added am33 to list of architectures supporting serial lines.
1999-07-28 Gary Thomas <gthomas@cygnus.co.uk>
 
* include/pkgconf/io_serial.h: Update descriptions to be more
generic (CL7x11 instead of CL7211).
 
1999-07-28 Jonathan Larmour <jlarmour@cygnus.co.uk>
 
* include/pkgconf/io_serial.h: Correct typos in CDL description
for serial port 2 driver
 
1999-07-26 Hugo Tyson <hmt@cygnus.co.uk>
 
* src/arm/ebsa285_serial.c: New file: device driver for the serial
device of the Intel StrongARM EBSA-285 evaluation board.

1999-06-27 Gary Thomas <gthomas@cygnus.co.uk>
 
* src/powerpc/quicc_smc_serial.c (quicc_smc_serial_init): More robust
initialization, with data cache disabled. This seems to fix the
random failures described below.
 
* tests/ser_test_protocol.inl: Add configuration for QUICC/MBX860.
Added some delays in the configuration change code to make QUICC
happy [didn't help much although the manual says they are required].
 
* src/powerpc/quicc_smc_serial.h (UART_BITRATE): Rewrote macro to
match what the Linux driver uses - still doesn't work well, though.
 
* src/powerpc/quicc_smc_serial.c: Lots of changes trying to get the
serial driver working and robust. At this point it works quite well,
using the default buffer sizes. Changing from the defaults seem to
easily break it though, certainly on input. Also, changing the baud
rate seems to not work reliably.
 
* src/common/serial.c: Add some tracing/debug info to try and debug
problems with QUICC serial driver. These are hard disabled with
"XX_" prepended to "CYGDBG_DIAG_BUF". Enabling them gives information
about how/when data are delivered from the serial driver.
 
* include/pkgconf/io_serial.h: Adjust limits and defaults on number and
size of buffers with values that seem to work.
 
1999-06-21 Jesper Skov <jskov@cygnus.co.uk>
 
* src/sh/sh_sci_serial.c: Rearranged inclusion of .inl file a bit

* include/pkgconf/io_serial.h: Fix CDL for number of buffers.

1999-06-20 Gary Thomas <gthomas@cygnus.co.uk>

* src/mn10300/mn10300_serial.c (mn10300_serial_config_port):
Wait for the serial device to become acquiescent before disabling
it. This prevents cygmon's outgoing characters getting corrupted
due to transmission being disabled.

* tests/PKGconf.mak:
* tests/ser_test_protocol.inl:
Added two simple TTY tests.
 
1999-04-07 Hugo Tyson <hmt@cygnus.co.uk>
 
* src/sparclite/sleb_sdtr.h: Include cyg/hal/hal_io.h for I/O
macros instead of hal_diag.h where they had evolved before.

* src/sparclite/sleb_sdtr.c (sleb_sdtr_start_xmit): Fix timing race
when enabling xmit interrupts.
 
1999-03-26 Gary Thomas <gthomas@cygnus.co.uk>
 
* src/sparclite/sleb_sdtr.c: Change how the port is set up. The transmitter
is now always enabled, just the interrupts are masked/unmasked to control it.
This lets the serial driver cooperate with Cygmon on the port used for GDB.
Note that currently serial input does not work for CON1 since Cygmon is
taking all of the receive interrupts for itself.
(sleb_sdtr_tx_DSR): Need to keep track whether xmit interrupt should be
enabled - otherwise it can get enabled incorrectly and we get interrupted
to death!
 
1999-03-26 Jesper Skov <jskov@cygnus.co.uk>
 
* tests/ser_test_protocol.inl: Send a DONE message after a no-echo
binary packet.

* tests/serial5.c:
* tests/serial4.c:
* tests/serial3.c:
* tests/serial2.c:
* tests/serial1.c:
Make these build when no kernel present; include of testcase
was the wrong side of the ifdef.
 
1999-03-26 Jesper Skov <jskov@cygnus.co.uk>
 
* tests/serial5.c:
* tests/serial4.c:
* tests/serial3.c:

Moved NOP check to ser_test_protocol open call.

1999-03-24 Nick Garnett <nickg@cygnus.co.uk>
 
* src/mips/tx3904_serial.c:
Now uses CYGHWR_HAL_MIPS_CPU_FREQ_ACTUAL to get CPU
frequency. This is a little more accurate than using
CYGHWR_HAL_MIPS_CPU_FREQ.
 
1999-03-24 Gary Thomas <gthomas@cygnus.co.uk>

1999-03-23 Nick Garnett <nickg@cygnus.co.uk>
 
* src/mn10300/mn10300_serial.c: Now initially mask TX interrupts
at initialization and unmask/remask in start/stop xmit
routines. This has no real effect on the hardware, but the
simulator does not implement the LCR_TXE bit properly, resulting
in spurious TX interrupts during diagnostic output.
This was the cause of the slow output reported in PR 19559.
 
1999-03-23 Gary Thomas <gthomas@cygnus.co.uk>

devices tied to the platform and not the serial I/O package. This
means that only the devices appropriate to a given platform can be
enabled.
 
* misc/serial.c: Better use of alarms - only trigger at the time of
the next timeout. Moved timeout functions to new file "timeout.inl".
 
* src/common/serial.c (serial_get_config): Add support for
CYG_IO_GET_CONFIG_SERIAL_INPUT_FLUSH and CYG_IO_GET_CONFIG_SERIAL_ABORT.
