|
|
* cdl/hal_i386_pcmb.cdl:
|
| 5 |
|
|
* include/pcmb_io.h: Increase PCI space to include all possible
|
| 6 |
|
|
busses, slots, etc. Required because defaults are often too small.

|
|
* src/pcmb_misc.c (hal_pcmb_init): Disable NMI at this point since
|
| 10 |
|
|
no real handlers are in place to handle it. This fixes a problem
|
| 11 |
|
|
with manual reset code for IDE drivers which can cause NMI.

|
|
* support/gfxmode.c:
|
| 16 |
|
|
A utility to find out what graphics modes are available on any
|
| 17 |
|
|
given PC.
|
| 18 |
|
|
|
| 19 |
|
|
* include/pcmb.inc:
|
| 20 |
|
|
Change the graphics mode during RedBoot startup, when configured
|
| 21 |
|
|
to do so.
|
| 22 |
|
|
|
| 23 |
|
|
* cdl/hal_i386_pcmb.cdl:
|
| 24 |
|
|
Add new configuration option for changing the graphics mode
|
| 25 |
|
|
during RedBoot startup.

|
* include/pcmb_serial.h:
|
| 30 |
|
|
* src/pcmb_serial.c:
|
| 31 |
|
|
Added a simple validation test for serial devices. If the status
|
| 32 |
|
|
register reads back all ones we decide that the device is absent
|
| 33 |
|
|
and mark it invalid. We test this elsewhere to avoid touching the
|
| 34 |
|
|
device again. This should help to cope with various problems with
|
| 35 |
|
|
PCs that come with only one serial port.

|
|
| 39 |
|
|
* src/pcmb_screen.c: Restore sensible num lock behaviour after the
|
| 40 |
|
|
last change.
|
| 41 |
|
|
(KBScanTable): Fix scan table size.
|
| 42 |

|
2001-11-29 Trenton D. Adams
|
| 44 |
|
|
|
| 45 |
|
|
* src/pcmb_screen.c: Support numeric keypad and ctrl-alt-del for
|
| 46 |
|
|
rebooting.
|
| 47 |
|
|
|
| 48 |
|
|
2001-11-23 Nick Garnett
|
| 49 |
|
|
|
| 50 |
|
|
* include/pcmb_io.h (PC_WRITE_SCREEN): Wrap positions beyond end
|
| 51 |
|
|
of screen back to start.

|
* src/pcmb_misc.c (hal_pcmb_init): Fix typo:
|
| 56 |

CYGPKG_HAL_I386_PCMB_HAL_MEMSIZE_BIOS ->
|
| 57 |
|
|
CYGPKG_HAL_I386_PCMB_MEMSIZE_BIOS

2001-10-19 Ian Campbell
|
| 60 |
|
|
|
| 61 |
|
|
* cdl/hal_i386_pcmb.cdl: Add cdl_options for
|
| 62 |
|
|
CYGPKG_HAL_I386_PCMB_MEMSIZE to allow configuration of how memory
|
| 63 |
|
|
is detected. Change CYGNUM_HAL_RTC_PERIOD to use default_value
|
| 64 |
|
|
rather than calculated (so it can be overridden in the platform).
|
| 65 |
|
|
* src/pcmb_misc.c: Implement CYGPKG_HAL_I386_PCMB_MEMSIZE
|
| 66 |
|
|
configuration options.
|
| 67 |
|
|

|
| 74 |
|
|
|
| 75 |
|
|
2001-10-01 Ian Campbell
|
| 76 |
|
|
|
| 77 |
|
|
* include/pcmb_io.h: Include CYGBLD_HAL_PLATFORM_H rather than
|
| 78 |
|
|
. Also include so the
|
| 79 |
|
|
define is available.
|
| 80 |
|
|
|
| 81 |
|
|
2001-09-14 Mark Salter
|
| 82 |
|
|
|
| 83 |
|
|
* include/pcmb_io.h (HAL_IDE_READ_ALTSTATUS): Add 2 for correct offset.
|
| 84 |
|
|
(HAL_IDE_WRITE_CONTROL): Ditto.
|
| 85 |
|
|
|
| 86 |
|
|
2001-08-22 Nick Garnett
|
| 87 |
|
|
|
| 88 |
|
|
* src/pcmb_misc.c: Added spinlock to clock read operation.
|
| 89 |
|
|
|
| 90 |
|
|
* include/pcmb_io.h (PC_WRITE_SCREEN_*): Added casts to make these
|
| 91 |
|
|
macros more universal.

| 92 |
|
|
|
| 93 |
|
|
* src/pcmb_smp.c: Added this file to contain all SMP related
|
| 94 |
|
|
code. This includes parsing the MP structures; initializing the
|
| 95 |
|
|
APIC and IOAPIC; starting the CPUs; interrupt mapping; inter-CPU
|
| 96 |
|
|
interrupts; and CPU synchronization in the event of a debuggable
|
| 97 |
|
|
exception.
|
| 98 |
|
|
Note: there is still a _lot_ of debugging code in here, mostly
|
| 99 |
|
|
disabled, which needs cleaning up. Also, if this code is to ever
|
| 100 |
|
|
be released to the public, it should probably be tidied up a bit
|
| 101 |
|
|
more.
|
| 102 |
|
|
|
| 103 |
|
|
* include/pcmb_intr.h: Added SMP support. This includes the
|
| 104 |
|
|
inter-CPU interrupt vectors, interrupt masking, acknowledge, and
|
| 105 |
|
|
CPU affinity via the APIC and IOAPIC.
|
| 106 |
|
|
|
| 107 |
|
|
* cdl/hal_i386_pcmb.cdl: Added configury to compile pcmb_smp.c
|
| 108 |
|
|
only when SMP is enabled. Also define HAL_PLATFORM_EXTRA to
|
| 109 |
|
|
contain the SMP-ness of the HAL, so that RedBoot can report it.
|
| 110 |

|
| 112 |

|
| 123 |
|
|
* include/pcmb_intr.h: Revert below change - not relevant in this case
|
| 124 |
|
|
for clobbers
|
| 125 |
|
|
|
| 126 |
|
|
2001-07-04 Jonathan Larmour
|
| 127 |
|
|
|
| 128 |
|
|
* include/pcmb_intr.h: Be pedantic about register constraint syntax
|
| 129 |
|
|
to satisfy newer compilers
|
| 130 |
|
|
|
| 131 |
|
|
2001-05-16 Jonathan Larmour
|
| 132 |
|
|
|
| 133 |
|
|
* src/pcmb_misc.c (hal_pc_clock_initialize): Use mode 2 (rate generator)
|
| 134 |
|
|
instead of mode 3 (square wave).

Created this package to provide the support needed to run eCos
|
| 182 |
|
|
binaries on an i386 PC using a standard motherboard. This package
|
| 183 |
|
|
provides support for the standard PC devices: timers, interrupt
|
| 184 |
|
|
controller, serial ports, ASCII display, keyboard, PCI bus
|
| 185 |
|
|
etc. that are found on all PC compatible platforms. It does not
|
| 186 |
|
|
provide support for devices that may also be found on modern
|
| 187 |
|
|
motherboards, such as ethernet, sound and video devices. These are
|
| 188 |
|
|
supported by drivers elsewhere.
