| 14 avoid padded output sections (PR 19787) | |
| 15 | |
| 16 1999-04-07 Hugo Tyson <hmt@cygnus.co.uk> | |

| 19 | |
| 20 1999-03-16 Hugo Tyson <hmt@cygnus.co.uk> | |
| 21 | |
| 22 * include/halboot.si: Add a dummy LED macro for debug in the | |
| 23 vectors.S; correct a scary line length. | |
| 24 | |
| 25 1999-03-04 Gary Thomas <gthomas@cygnus.co.uk> | |
| 26 | |
| 27 * include/pkgconf/hal_sparclite_sim.h: Take out DEVICES dependencies. | |
| 28 | |
| 29 1999-03-04 John Dallaway <jld@cygnus.co.uk> | |
| 30 | |
| 31 * include/pkgconf/*.ldi: give all LDI files unique names so | |
| 32 that they can co-exist in an eCos build tree (PR 19184) | |
| 33 * include/pkgconf/*.mlt: give all MLT files unique names so | |
| 34 that they can co-exist in an eCos build tree (PR 19184) | |

| 38 These log entries from 1999-02-22 to 1999-02-24 were executed in | |
| 39 a branch; this change is a merge of that branch into the trunk. | |
| 40 | |
| 41 (1999-02-23 John Dallaway <jld@cygnus.co.uk>) | |
| 42 | |
| 43 * include/pkgconf/hal_sparclite_sim.h: New rules | |
| 44 CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_GDB | |
| 45 CYGPKG_HAL_SPARCLITE_SIM precludes CYGPKG_DEVICES_SERIAL_RS232_COMMON | |
| 46 | |
| 47 (1999-02-22 Hugo Tyson <hmt@cygnus.co.uk>) | |
| 48 | |
| 49 * src/hal_priv.c (hal_board_prestart, hal_board_poststart): | |
| 50 Shut down the erc32 watchdog in and enable interrupts in these two | |
| 51 new routines. | |
| 52 | |
| 53 * include/halboot.si: | |
| 54 Remove N/A code that I was just storing here, and install the real | |
| 55 vector instructions in this fragment; there be cache-wangling to | |
| 56 do in hardware cases either side of the vector installation. | |
| 57 | |
| 58 1999-02-20 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 59 | |
| 60 * include/hal_xpic.h: | |
| 61 Rename CYG_VECTOR_* -> CYGNUM_HAL_INTERRUPT_* | |
| 62 | |
| 63 * src/hal_priv.c: | |
| 64 Add a FIX ME | |
| 65 | |
| 66 1999-02-08 John Dallaway <jld@cygnus.co.uk> | |
| 67 | |
| 68 * src/sim.ld: Remove platform-specific linker script for | |
| 69 MLT compliance. | |
| 70 | |
| 71 * src/PKGconf.mak: Remove build rules for sim.ld. | |
| 72 | |
| 73 * include/pkgconf/ram.*: Add MLT save file and and linker | |
| 74 script fragment for RAM startup. | |
| 75 | |
| 76 1999-02-01 Hugo Tyson <hmt@cygnus.co.uk> | |
| 77 | |
| 78 * include/halboot.si: | |
| 79 New file: performs platform-oriented setup of RAM and cache | |
| 80 controllers, and quietens any interrupt sources. | |
| 81 | |
| 82 * include/pkgconf/hal_sparclite_sim.h: | |
| 83 Correct comments/CDL description of sim invocation. | |
| 84 | |
| 85 1999-01-28 Hugo Tyson <hmt@cygnus.co.uk> | |
| 86 | |
| 87 * include/hal_cache.h: NEW FILE to this directory; moved here from | |
| 88 the sparclite/arch tree; cache control is very much board-specific | |
| 89 | |
| 90 * include/hal_clock.h: NEW FILE to this directory; it was a part | |
| 91 of hal_intr.h, but is now here because the clock is target determined. | |
| 92 | |
| 93 * include/hal_xpic.h: NEW FILE to this directory; it was a part of | |
| 94 hal_intr.h, but is now here because the detail of interrupot | |
| 95 control is target determined. | |
| 96 | |
| 97 * src/hal_priv.c: NEW FILE to this directory; it was a part | |
| 98 of hal_intr.h, but is now here because the clock is target | |
| 99 determined, and it's the clock that needs a local variable. | |
| 100 | |
| 101 * src/PKGconf.mak (COMPILE): compile it. | |
| 102 | |
| 103 | |
| 104 1999-01-26 Hugo Tyson <hmt@cygnus.co.uk> | |
| 105 | |
| 106 * src/sim.ld: | |
| 107 Add copyright notice. (Though these files will later be generated | |
| 108 by a tool and so not copyright, these default setups are.) | |
| 109 | |
| 110 1999-01-22 Hugo Tyson <hmt@cygnus.co.uk> | |
| 111 | |
| 112 * src/sim.ld: | |
| 113 Remove some bogus comments. | |
| 114 | |
| 115 1999-01-21 Jonathan Larmour <jlarmour@cygnus.co.uk> | |
| 116 | |
| 117 * src/sim.ld: | |
| 118 Remove all traces of non-CYG_KERNEL_USE_INIT_PRIORITY code | |
| 119 | |
| 120 1999-01-21 Hugo Tyson <hmt@cygnus.co.uk> | |
| 121 | |
| 122 * src/sim.ld: | |
| 123 Align bss and rom/ram_data starts and ends by 8 bytes to permit | |
| 124 fast copy routines. | |
| 125 | |
| 126 1999-01-19 Hugo Tyson <hmt@cygnus.co.uk> | |
| 127 | |
| 128 Modified files in arch: | |
| 129 * include/hal_arch.h | |
| 130 * include/hal_intr.h | |
| 131 * src/PKGconf.mak | |
| 132 * src/context.S | |
| 133 * src/hal_intr.c | |
| 134 * src/vec_ivsr.S | |
| 135 * src/vec_xvsr.S | |
| 136 * src/vectors.S | |
| 137 | |
| 138 New files in arch: | |
| 139 * src/hal_boot.c (bss initialization, constructors &c) | |
| 140 * include/hal_cache.h (empty but required header) | |
| 141 | |
| 142 Modified files in sim: | |
| 143 * include/hal_diag.h | |
| 144 | |
| 145 Lots more progress; essentially, everything now works. | |
| 146 | |
| 147 Simulator's treatment of stdio is poor though, it doesn't work | |
| 148 under pkgtest. This has been slowing me up. | |
| 149 | |
| 150 1999-01-14 Hugo Tyson <hmt@cygnus.co.uk> | |
| 151 | |
| 152 * ecc/ecc/hal/sparclite/...: | |
| 153 | |
| 154 Initial checkin of SPARClite HAL; it doesn't work yet, except the | |
| 155 most trivial of tests - timer and interrupt manipulation stuff is | |
| 156 entirely absent. | |
| 157 | |
| 158 Here's some documentation of the initial checkin tree; this will | |
| 159 change, as platform dependent stuff moves correctly into the sim | |
| 160 or <board> directories. | |
| 161 | |
| 162 arch/current/include: | |
| 163 basetype.h nothing much here. | |
| 164 vectors.h definitions of symbols shared between the | |
| 165 various vector code assembler files, can be | |
| 166 included in both C and assembler. | |
| 167 hal_intr.h various macros for clock and interrupt | |
| 168 control plus the eCos vector numbering scheme; we | |
| 169 map thus: | |
| 170 what SPARC trap type eCos vector numbers | |
| 171 ----------------------------------------------- | |
| 172 (not used) --- 0 | |
| 173 interrupts (17-31) 1-15 | |
| 174 user traps (128-255) 16 | |
| 175 exceptions (1-9,36==4) 17-25 | |
| 176 others (10,?) 26 | |
| 177 ----------------------------------------------- | |
| 178 Trap types 5 and 6 which would be eCos vectors 21 | |
| 179 and 22 are handled in the trampoline code in | |
| 180 file src/vectors.S | |
| 181 hal_arch.h definition of a thread context, plus | |
| 182 macros for thread switching and the like. Some | |
| 183 ancillary bit twiddling macros and cache barriers | |
| 184 too. | |
| 185 | |
| 186 arch/current/include/pkgconf: | |
| 187 hal_sparclite.h pkgconf config/header file. | |
| 188 | |
| 189 arch/current/src: | |
| 190 vectors.S boot-up stuff, trampoline code that hangs | |
| 191 on the interrupt/trap vector, handlers for window | |
| 192 under/overflow. Saves some state in registers | |
| 193 then jumps to the interrupt or exception VSR | |
| 194 respectively. | |
| 195 Also instantiates the VSR table. | |
| 196 vec_ivsr.S the default interrupt VSR; it establishes | |
| 197 a C calling environment (ie. anticipates a window | |
| 198 overflow) then locks the scheduler, calls the ISR | |
| 199 with appropriate arguments, and then interrupt_end() | |
| 200 before undoing that environment, anticipating | |
| 201 window underflow and returning to the interrupted | |
| 202 instruction. | |
| 203 vec_xvsr.S the default exception AKA trap VSR; does | |
| 204 the same as the interrupt one but without the | |
| 205 scheduler lock or interrupt end. | |
| 206 hal_intr.c instantiates the ISR table used by the | |
| 207 code above. | |
| 208 context.S context switch code, saves and loads up a | |
| 209 whole register state, coroutine or longjump-like. | |
| 210 icontext.c initializes a context to "jump" to in | |
| 211 context.S at the birth of a new thread. | |
| 212 | |
| 213 sim/current/include: | |
| 214 hal_diag.h macros to deal with debugging output via a | |
| 215 fake serial device of some kind; initially empty, | |
| 216 but definitely board/sim dependent. | |
| 217 | |
| 218 sim/current/include/pkgconf: | |
| 219 hal_sparclite_sim.h pkgconf config/header file. | |
| 220 | |
| 221 sim/current/src: | |
| 222 sim.ld linker script bits for "sim" target. | |
