instead allow an installed ROM monitor to handle them. This is
the most basic support which is likely to be common to most
implementations of ROM monitor.

## Although these two startup types are, on the face of it, very different,
## the actual work that needs to be done here for them both is much the same.
## In both cases the system has been initialized in real mode and the transition
## to 32 bit protected mode has been done. Here all we need to do is set up

Functionality of eCos on the PC
-------------------------------
 
This release of eCos for the PC target is based on the code
contributed by Patrick O'Grady (patrick@softprocess.com). With the
exception of some minor reorganization it is essentially the same as
Patrick's release.
 
There are a number of things that are currently incomplete and are
listed here to indicate where this code is expected to change in the
future. These include:
 
- The current exception handling code is derived from the original GDB
stubs and is only really adequate for handling debugging
requirements. We will need to provide full support for exception
delivery to applications. As a result of this, nearly all of the
related code will need to be rewritten.
 
- Currently the GDB stub monitor is used just as a loader, once the
program is running any debug duties are taken by a separate set of
GDB stubs in the loaded image. To make this image smaller it is
desirable to use the GDB stubs already present in the monitor. This
requires some reorganization of the VSR table and the addition of a
vector table for calls between the two pieces of code.
 
- Related to the previous item, support for using Ctrl-C when there
are no stubs present in the executable need to be added. This
differs from the current support that interacts with the included
stubs since it must interact with the monitor via the vector table.
 
- At present the stub monitor can only boot from floppy disk. It
should be possible to make this code more generic so that it can
boot from hard disk and CD too. Support for applications that can
boot in this way should also be possible, as is booting via
BOOTP/TFTP from a network interface.
 
- Complete the HAL port, including addition of cache control macros
and a cleaner distinction between architecture, variant and
platform.

/v2_0/ChangeLog
0,0 → 1,485
2003-04-10 Nick Garnett <nickg@balti.calivar.com>
 
* include/pkgconf/mlt_i386_pc_rom.ldi: Brought list of sections up
to date with other files.
 
2003-01-22 Jonathan Larmour <jifl@eCosCentric.com>
 
* include/pkgconf/hal_i386_pc.h: Old file. Remove.
 
2002-11-28 Nick Garnett <nickg@ecoscentric.com>
 
* src/plf_stub.c: Removed redundant reinitialization of VSR table
in hal_pc_stubs_init(). This has already been done in
hal_platform_init() and reinitializing here destroys the FPU
switch VSR.
 
* src/plf_misc.c (hal_platform_init):
Added configuration and test to avoid overwriting the FPU switch
VSR with the default VSR. This caused problems with stand-alone
application that use lazy FPU switching.
Moved call to hal_ctrlc_isr_init() to after call to
hal_if_init(). Previously, stand-alone applications had problems
with ctrl-c handling because the CALL_HACK stuff didn't work.
 
* cdl/hal_i386_pc.cdl:
Added GRUB startup option. This enables support for booting from
the GRUB bootloader.
Added CYGDBG_HAL_DEBUG_GDB_INITIAL_BREAK option to force a
breakpoint just before calling cyg_start(). This is insinuated
into the CYGPKG_HAL_DEBUG part of the tree, and conditioned to
only work for stand-alone apps with the stubs included.
 
* include/platform.inc: Added GRUB startup support.
 
* include/pkgconf/mlt_i386_pc_grub.mlt:
* include/pkgconf/mlt_i386_pc_grub.ldi:
* include/pkgconf/mlt_i386_pc_grub.h:
Added these MLT files to support the new GRUB startup option.
 
* misc/menu.lst: Added this example GRUB menu configuration file.
2002-05-07 Gary Thomas <gthomas@redhat.com>
 
* cdl/hal_i386_pc.cdl:
Standardize CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT usage.
 
2002-04-29 Jonathan Larmour <jlarmour@redhat.com>
 
* src/romboot.S:
Don't use .file as it can confuse debugging since the .file
doesn't contain the path and therefore the debugger will never
know where it lives! This conflicts with using -Wa,--gstabs.
 
2002-04-23 Jonathan Larmour <jlarmour@redhat.com>
 
* cdl/hal_i386_pc.cdl: Remove unused compile line.
 
2001-12-07 Nick Garnett <nickg@redhat.com>
 
* include/plf_intr.h: Added definition of HAL_DELAY_US() so that
this is used instead of the delay loop in delay_us(). This is
necessary to handle fast Pentiums and Athlons.
 
* misc/redboot_FLOPPY_D850GB.ecm: Removed reference to SMP.
 
2001-10-16 Mark Salter <msalter@redhat.com>
 
* misc/redboot_FLOPPY_D850GB.ecm: New file. RedBoot config for
Intel D850GB motherboard.
 
* src/hal_diag.c: Setup pc_ser_channels based on CDL.
 
2001-10-12 Jonathan Larmour <jlarmour@redhat.com>
 
* cdl/hal_i386_pc.cdl: Parent CYGBLD_BUILD_REDBOOT_BIN_ROM and
CYGBLD_BUILD_REDBOOT_BIN_FLOPPY under a CYGBLD_BUILD_REDBOOT_BIN_ROM
component for better cross-platform consistency.
 
2001-10-08 Ian Campbell <icampbell@arcom.co.uk>
 
* cdl/hal_i386_pc.cdl: CYGBLD_BUILD_I386_ROMBOOT and
CYGBLD_BUILD_REDBOOT_BIN_ROM moved here from hal_i386.cdl in the
arch package. Rename CYGBLD_BUILD_REDBOOT_BIN to
CYGBLD_BUILD_REDBOOT_BIN_FLOPPY for consistency.
* src/romboot.S: Moved from arch package.
* src/romboot.ld: Moved from arch package.
 
2001-10-05 Mark Salter <msalter@redhat.com>
 
* src/plf_stub.c (hal_pc_stubs_init): Install idt entry for GNUPro
syscalls.
 
* misc/redboot_FLOPPY.ecm: Turn on CYGSEM_REDBOOT_BSP_SYSCALLS.
 
* include/plf_misc.h: Add extern decl for cyg_hal_pc_set_idt_entry.
 
2001-10-02 Jonathan Larmour <jlarmour@redhat.com>
 
* cdl/hal_i386_pc.cdl
(CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT): Allow user to
change value.
 
2001-09-28 Ian Campbell <icampbell@arcom.co.uk>
 
* include/platform.inc (hal_cpu_init): Initialise %ss.
Be more pedantic about register names matching opcode suffixes.
 
2001-09-07 Jonathan Larmour <jlarmour@redhat.com>
 
* misc/redboot_FLOPPY.ecm: Disable
CYGSEM_REDBOOT_VALIDATE_USER_RAM_LOADS
* misc/redboot_ROM.ecm: Ditto.
* misc/redboot_FLOPPY_SMP.ecm: Ditto.
 
2001-09-05 Jonathan Larmour <jlarmour@redhat.com>
 
* src/plf_misc.c (hal_platform_init): If not RAM startup, install
exception VSRs.
 
2001-08-22 Nick Garnett <nickg@redhat.com>
 
* include/pkgconf/mlt_i386_pc_floppy.ldi:
* include/pkgconf/mlt_i386_pc_floppy.mlt:
Moved load base address from 0x2000 to 0x3000.
We now use page 0x2000 for SMP related data including the slave
CPU startup trampoline and various data structures that need to be
shared between RedBoot and the application.
 
* misc/redboot_FLOPPY_SMP.ecm: Added this file to configure an
SMP-aware RedBoot floppy. If SMP applications are to be run it is
essential that this version of RedBoot be used because a degree of
cooperation is required to get the CPUs going, and to handle
exceptions cleanly.
 
* src/plf_misc.c (hal_platform_init): Added call to cyg_hal_smp_init().
 
 
* include/platform.inc (hal_idt_init): Added entries to set up IDT
entries 48..67.
 
2001-08-13 Jonathan Larmour <jlarmour@redhat.com>
 
* cdl/hal_i386_pc.cdl: Fix CYG_HAL_STARTUP description.
 
2001-07-13 Nick Garnett <nickg@redhat.com>
 
* cdl/hal_i386_pc.cdl: Added requires statement to
CYGSEM_HAL_ROM_MONITOR option to turn off lazy FPU switching. ROM
monitors should not be playing these kinds of games.
 
2001-05-22 Jonathan Larmour <jlarmour@redhat.com>
 
* include/pkgconf/mlt_i386_pc_ram.mlt: Fix pci_window description.
 
2001-05-03 Nick Garnett <nickg@cygnus.co.uk>
 
* cdl/hal_i386_pc.cdl: Changed option
CYGIMP_HAL_I386_PCMB_SCREEN_SUPPORT to interface
CYGINT_HAL_I386_PCMB_SCREEN_SUPPORT.
 
2001-04-30 Nick Garnett <nickg@cygnus.co.uk>
 
[x86 branch]
* cdl/hal_i386_pc.cdl: Added options to convert ELF file to binary
for copying to a floppy disc.
 
2001-03-16 Nick Garnett <nickg@cygnus.co.uk>
 
[x86 branch]

(This is work in progress and is not yet complete.)
 
* include/pkgconf/mlt_i386_pc_rom.ldi:
* include/pkgconf/mlt_i386_pc_rom.h:

* include/pkgconf/mlt_i386_pc_ram.ldi:
* include/pkgconf/mlt_i386_pc_ram.h:
Fixed some bugs in these files with the size and layout of
RAM. This was causing the heap to be badly mangled.
 
2001-03-14 Nick Garnett <nickg@cygnus.co.uk>
 
[x86 branch]
* src/plf_misc.c (hal_platform_init): Added call to
hal_pcmb_init().
 
* include/platform.inc: Removed memory size stuff.
 
2001-03-13 Nick Garnett <nickg@cygnus.co.uk>
 
[x86 branch]
* src/plf_misc.c: Deleted old FP context switch code.
 
* include/platform.inc: Removed some now redundant code.
 
2001-03-08 Nick Garnett <nickg@cygnus.co.uk>
 
[x86 branch]
* src/plf_misc.c: ISR tables and cyg_hal_pc_set_idt_entry() moved
here from hal_startup.c. ISR table setup code tidied.
hal_delay_us() now works in 1s bursts to avoid arithmetic
overflow.
 
* src/hal_diag.c: Most of contents of file moved out to
pcmb_serial.c and pcmb_screen.c. This remains as an intialization
interface for those.

to 1.
 
* include/var_intr.h:
* include/variant.inc:

[x86 branch]
* src/var_misc.c: Rewrote clock init and access functions in terms
of HAL IO macros.

2000-03-15 Nick Garnett <nickg@cygnus.co.uk>
 
* src/hal_diag.c: Added code to handle keyboard input on PC when
using SCREEN diagnostics. This is as much for completeness and
future use than for any pressing current need.
 
* include/platform.inc: Fixed some mismatches between instruction
suffixes and operand sizes that the latest i386 assembler now
warns about. Also tidied up GDT and IDT load code and protected

description that appropriate versions of native linux tools can
also be used.
 
2000-03-01 Nick Garnett <nickg@cygnus.co.uk>
 
* src/plf_stub.c (cyg_hal_gdb_isr): Added check for a character
being available at the serial line. With the introduction of GDB O

interrupt and get stuck in hal_pc_get_char().
 
* include/var_intr.h:
Modified interrupt enable/disable code so that it is closer in
behavior to other HALs.
 
* include/platform.inc:
Changed floppy bootstrap code so it can load binaries greater than
64k and only loads the .text+.data parts, not the .bss.
 
2000-02-18 Jonathan Larmour <jlarmour@redhat.co.uk>
 
* cdl/hal_i386_pc.cdl (CYGBLD_BUILD_GDB_STUBS): When
building stubs, define every dependency required here rather than
in the template
 
2000-02-18 John Dallaway <jld@cygnus.co.uk>
 
* include/pkgconf/mlt_i386_pc_ram.mlt,
include/pkgconf/mlt_i386_pc_floppy.mlt:
 
Add/update memory layout save files to match the corresponding
linker script fragments.
 
2000-02-16 Nick Garnett <nickg@cygnus.co.uk>
 
* src/hal_diag.c: Added support for generating GDB O packets when
diagnosing to serial0.
