|
* include/pcmb.inc: To allow the BIOS timer interrupt handler to

switch off the drive, we need to make sure interrupts are enabled.

|
|
|
31 |
|
|
* include/pcmb_serial.h,
|
32 |
|
|
* src/pcmb_screen.c: define cyg_hal_plf_screen_position() which can
|
33 |

|
36 |
|
|
|
37 |
|
|
* include/pcmb_io.h: IDE init needs to return number of controllers

38 |
|
|
found.
|

|
|
2003-07-23 Nick Garnett
|
41 |
|
|
|
42 |
|
|
* include/pcmb_serial.h: Fixed bogus test on
|
43 |
|
|
CYGSEM_HAL_I386_PCMB_SCREEN_SUPPORT defined to test
|
44 |
|
|
CYGINT_HAL_I386_PCMB_SCREEN_SUPPORT > 0 instead.

2003-07-18 Nick Garnett
|
47 |
|
|
|
48 |
|
|
* cdl/hal_i386_pcmb.cdl:
|
49 |
|
|
Changed values for CYGNUM_HAL_RTC_NUMERATOR,
|
50 |
|
|
CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
|
51 |
|
|
"default_value" from "calculated". This makes it easier
|
52 |
|
|
to change these values globally.

|
|
57 |
|
|
* cdl/hal_i386_pcmb.cdl:
|
58 |
|
|
* include/pcmb_io.h: Increase PCI space to include all possible
|
59 |
|
|
busses, slots, etc. Required because defaults are often too small.
|
60 |
|
|
2002-04-29 Gary Thomas
|
61 |
|
|
|
62 |
|
|
* src/pcmb_misc.c (hal_pcmb_init): Disable NMI at this point since
|
63 |
|
|
no real handlers are in place to handle it. This fixes a problem
|
64 |
|
|
with manual reset code for IDE drivers which can cause NMI.

|
67 |
|
|
|
68 |
|
|
* support/gfxmode.c:
|
69 |
|
|
A utility to find out what graphics modes are available on any
|
70 |
|
|
given PC.
|
71 |
|
|
|
72 |
|
|
* include/pcmb.inc:
|
73 |
|
|
Change the graphics mode during RedBoot startup, when configured
|
74 |
|
|
to do so.
|
75 |
|
|
|
76 |
|
|
* cdl/hal_i386_pcmb.cdl:
|
77 |
|
|
Add new configuration option for changing the graphics mode
|
78 |
|
|
during RedBoot startup.

|
|
* include/pcmb_serial.h:
|
83 |
|
|
* src/pcmb_serial.c:
|
84 |
|
|
Added a simple validation test for serial devices. If the status
|
85 |
|
|
register reads back all ones we decide that the device is absent
|
86 |
|
|
and mark it invalid. We test this elsewhere to avoid touching the
|
87 |
|
|
device again. This should help to cope with various problems with
|
88 |
|
|
PCs that come with only one serial port.

2001-11-29 Jonathan Larmour
|
91 |
|
|
|
92 |
|

|
93 |
|
|
last change.
|
94 |
|
|
(KBScanTable): Fix scan table size.
|
95 |

|
2001-11-29 Trenton D. Adams
|
97 |
|
|
|
98 |
|
|
* src/pcmb_screen.c: Support numeric keypad and ctrl-alt-del for
|
99 |
|
|
rebooting.
|
100 |
|
|
|
101 |
|
|
2001-11-23 Nick Garnett
|
102 |
|
|
|
103 |
|
|
* include/pcmb_io.h (PC_WRITE_SCREEN): Wrap positions beyond end
|
104 |
|
|
of screen back to start.
|
105 |

|
|
106 |

|
* src/pcmb_misc.c (hal_pcmb_init): Fix typo:
|
109 |
|
|
CYGPKG_HAL_I386_PCMB_HAL_MEMSIZE_BIOS ->
|
110 |
|
|
CYGPKG_HAL_I386_PCMB_MEMSIZE_BIOS

2001-10-19 Ian Campbell
|
113 |
|
|
|
114 |
|
|
* cdl/hal_i386_pcmb.cdl: Add cdl_options for
|
115 |
|
|
CYGPKG_HAL_I386_PCMB_MEMSIZE to allow configuration of how memory
|
116 |
|
|
is detected. Change CYGNUM_HAL_RTC_PERIOD to use default_value
|
117 |
|
|
rather than calculated (so it can be overridden in the platform).
|
118 |
|
|
* src/pcmb_misc.c: Implement CYGPKG_HAL_I386_PCMB_MEMSIZE
|
119 |
|
|
configuration options.
|
120 |
|
|
|
121 |

2001-10-16 Mark Salter
|
122 |
|
|
|
123 |
|
|

|
124 |
|
|
how many serial ports to support.
|
125 |
|
|
* src/pcmb_screen.c (cyg_hal_plf_screen_init): Use CDL to determine
|
126 |
|
|
channel number for keyboard/screen.
|
127 |
|
|
|
128 |
|
|
2001-10-01 Ian Campbell
|
129 |
|
|
|
130 |
|
|
* include/pcmb_io.h: Include CYGBLD_HAL_PLATFORM_H rather than
|
131 |
|
|
. Also include so the
|
132 |
|
|
define is available.
|
133 |
|
|
|
134 |
|
|
2001-09-14 Mark Salter
|
135 |
|
|
|
136 |
|
|
* include/pcmb_io.h (HAL_IDE_READ_ALTSTATUS): Add 2 for correct offset.
|
137 |
|
|
(HAL_IDE_WRITE_CONTROL): Ditto.
|
138 |
|
|
|
139 |
|
|
2001-08-22 Nick Garnett
|
140 |
|
|
|
141 |
|
|
* src/pcmb_misc.c: Added spinlock to clock read operation.
|
142 |
|
|
|
143 |
|
|
* include/pcmb_io.h (PC_WRITE_SCREEN_*): Added casts to make these
|
144 |
|
|
macros more universal.

145 |
|
|
|
146 |
|
|
* src/pcmb_smp.c: Added this file to contain all SMP related
|
147 |
|
|
code. This includes parsing the MP structures; initializing the
|
148 |
|
|
APIC and IOAPIC; starting the CPUs; interrupt mapping; inter-CPU
|
149 |
|
|
interrupts; and CPU synchronization in the event of a debuggable
|
150 |
|
|
exception.
|
151 |
|
|
Note: there is still a _lot_ of debugging code in here, mostly
|
152 |
|
|
disabled, which needs cleaning up. Also, if this code is to ever
|
153 |
|
|
be released to the public, it should probably be tidied up a bit
|
154 |
|
|
more.
|
155 |
|
|
|
156 |
|
|
* include/pcmb_intr.h: Added SMP support. This includes the
|
157 |
|
|
inter-CPU interrupt vectors, interrupt masking, acknowledge, and
|
158 |
|
|
CPU affinity via the APIC and IOAPIC.
|
159 |
|
|
|
160 |
|
|
* cdl/hal_i386_pcmb.cdl: Added configury to compile pcmb_smp.c
|
161 |
|
|
only when SMP is enabled. Also define HAL_PLATFORM_EXTRA to
|
162 |
|
|
contain the SMP-ness of the HAL, so that RedBoot can report it.
|
163 |
|
|
|
164 |
|
|
2001-07-31 Mark Salter
|
165 |
|
|

|
174 |
|
|
|
175 |
|
|
* src/pcmb_misc.c (hal_pcmb_init): Silence warning
|
176 |
|
|
* include/pcmb_intr.h: Revert below change - not relevant in this case
|
177 |
|
|
for clobbers
|
178 |
|
|
|
179 |
|
|
2001-07-04 Jonathan Larmour
|
180 |
|
|
|
181 |
|
|
* include/pcmb_intr.h: Be pedantic about register constraint syntax
|
182 |
|
|
to satisfy newer compilers
|
183 |
|
|
|
184 |
|
|
2001-05-16 Jonathan Larmour
|
185 |
|
|
|
186 |
|
|
* src/pcmb_misc.c (hal_pc_clock_initialize): Use mode 2 (rate generator)
|
187 |
|
|
instead of mode 3 (square wave).
|
188 |
|
|
|

Created this package to provide the support needed to run eCos
|
235 |
|
|
binaries on an i386 PC using a standard motherboard. This package
|
236 |
|
|
provides support for the standard PC devices: timers, interrupt
|
237 |
|
|
controller, serial ports, ASCII display, keyboard, PCI bus
|
238 |
|
|
etc. that are found on all PC compatible platforms. It does not
|
239 |
|
|
provide support for devices that may also be found on modern
|
240 |
|
|
motherboards, such as ethernet, sound and video devices. These are
|
241 |
|
|
supported by drivers elsewhere.
