1143 Make UART transmitter-empty interrupts match both 16450 and 16550 behavior. sfurman 7769d 15h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
1116 There was a bug in the simulator's UART implementation that caused the
UART's LSR register to become corrupted. This was due to an
assumption that 'char' is an unsigned type, but that is not true on
all platforms.

When the char type is signed and a character is read in the range
0x80-0xff, the high bit is sign-extended into the upper bits of an
entry in the receive FIFO. When the character reaches the head of the
FIFO, the upper bits of the FIFO entry are OR'ed into the LSR, causing
the LSR to be set to 0xFF.

A simple cast fixes the problem.

997 PRINTF should be used instead of printf; command redirection repaired markom 7998d 12h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
970 Testbench is now running on ORP architecture platform. simons 8005d 23h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
884 code cleaning - a lot of global variables moved to runtime struct markom 8042d 10h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
821 ugly bug with duplicate redefined i removed markom 8128d 07h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
806 uart now partially uses scheduler markom 8133d 13h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
805 kbd, fb, vga devices now uses scheduler markom 8133d 14h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
713 lot of small minor improvements: code documented, cleaned; runs at about same speed when not actually logging, but exe_log is enabled; raw_stats now run only with simple execution - enable RAW_USAGE_STATS macro markom 8170d 12h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
549 enabled parameters removed from devices, which also have number of devices; command line --output-cfg parameter added markom 8224d 08h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
530 THRI interrupt fixed. simons 8227d 01h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
529 Bug in receiver fixed. simons 8227d 03h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
492 uart THRE interrupt immedialty after write to IER markom 8243d 11h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
490 clkcycle parsing problem fixed markom 8244d 06h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
424 memory configuration file joined into .cfg file; *mem.cfg are obsolete; read-only and write-only memory is supported; memory logging is not yet supported; update of testbench - only cache test fails, since it writes to RO memory markom 8253d 10h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
423 changed break behaviour and interrupt pending; interrupt line chabnged to 15; sync bug in mode switch markom 8254d 06h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
411 acv uart testsuite now works (without modem test) markom 8257d 11h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
409 some minor changes to or1ksim; Testbench except.s modified. Interrupt test almost finished for uart ACV. markom 8258d 11h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
385 check testbench now modified to work with new report output markom 8267d 07h /or1k/tags/nog_patch_43/or1ksim/peripheral/16450.c
