• cc4d7561ed devamlc comments and cleanups Jim 2011-08-27 20:23:32 -04:00
• 7230a331f3 Back out telnet changes for Kermit; they screwed up regular telnet Jim 2011-08-27 20:11:37 -04:00
• 927d8c9c13 Tried to fix Kermit telnet negotiation so /nowait isn't required; worked for most things, but not for DO KERMIT / WILL KERMIT - still hangs. :( Jim 2011-08-27 17:04:59 -04:00
• d7dc1847a8 amlc.cfg: can dedicate AMLC lines to an IP address. This is useful for serial device servers connected to a serial printer for example, where the SDS initiates the telnet connect to the Prime when the printer is turned on. Jim 2011-08-27 08:29:44 -04:00
• 51aaaeb341 Reverse order of devpnc.h and devamlc.h: both use MAXHOSTLEN Jim 2011-08-27 07:34:52 -04:00
• 5a5be64d17 Split devamlc into .h file, correct devpnc.h brace bug (hobby) Jim 2011-08-24 17:42:35 -04:00
• b643ed80ed Add Unix versions of smad, smag for Prime pdevs Jim 2011-08-24 17:15:16 -04:00
• d398a93143 Removed PNCXSNAK - don't need it Jim 2011-08-24 17:12:36 -04:00
• 50a95cc1ba Use close(): shutdown() causes a descriptor leak. Add a trace when a connection is accepted. Jim 2011-08-19 17:04:31 -04:00
• 49eaf4b21b Don't zero uid of disabled node, to avoid "can't find uid" error. Jim 2011-08-19 16:15:16 -04:00
• a3a1f06d6f When a packet is too big to receive, disable the node it came from. This happens for example if a node is configured with a 1024-word packet size and sends to a node with a 256-word packet size. In the emulator PNC design, the packet has already been ACK'd at the sending side, so there is no way to indicate a transmission error other than taking down the connection. Since the error will just occur again, the best course is to disable the node until the next reboot. Primenet will disconnect the sending and receive nodes from each other in about 30 seconds. Jim 2011-08-19 16:04:39 -04:00
• 2a698b038d Don't NAK xmit packets. prmnt1 seems to indicate that a packet no one accepts is NAK'd, but if we do that, it keeps getting sent over and over. If we're not connected, retries don't make sense. Jim 2011-08-19 13:37:02 -04:00
• 6b8abd3a8b Use current hg rev when building Jim 2011-08-18 20:58:18 -04:00
• aba2688490 Don't enable tsrc$$ trace hack whenever tracing is enabled. Jim 2011-08-18 14:07:23 -04:00
• 063a23144a Fix several devpnc bugs: 1. Need 32-bit integer for dma address so newer Primos can use I/O segments other than 0. 2. Ignore interrupted select() 3. Set fd to -1 after closing when not connected, to avoid bad file descriptor error Jim 2011-08-18 14:04:55 -04:00
• 05251fbcce Allow tracing 3-digit user numbers vs 2. System processes sometimes have high user numbers. Jim 2011-08-18 13:35:33 -04:00
• 459873ff90 Add stlb/iotlb trace option "tlb", set T_EAS when requested Jim 2011-08-18 13:17:54 -04:00
• 2ef1438900 Updated some comments. Still some confusion about PTLB re: IOTLB. Jim 2011-08-18 10:10:28 -04:00
• 8200cff70d devpnc: don't print disconnected message in error.log when we were trying to connect but failed. Only print them when we actually were connected. Jim 2011-08-17 16:28:58 -04:00
• 1bc93f304a devpnc: ensure ring.cfg unique id is really unique: it determines the node-id for incoming connections. Jim 2011-08-17 15:48:01 -04:00
• 834cb1977f Add simulate token OCP, just for documentation purposes. This is only used by T&M's. Jim 2011-08-17 12:05:21 -04:00
• a68971cc1c Flush tracefile every line only when "flush" arg is used. This is useful for situations where the emulator bombs, eg, with a Unix seg fault. But it's slower too, so make it optional. Jim 2011-08-17 09:35:01 -04:00
• 8c635c19c8 Minor devpnc edits, change MAXACCEPTTIME from 5 to 15 seconds Jim 2011-08-16 18:34:16 -04:00
• 1b943bce0a Enabled PNC async I/O, changed poll from 100ms to 1 sec, performance seems to be fine. Remote ld -size no longer takes 1 second per entry, but that is probably because of earlier PNC changes. Jim 2011-08-16 18:04:13 -04:00
• 8aac162418 Use select() to find out if any node has sent us data; more efficient than doing a read on each socket. Jim 2011-08-16 17:55:55 -04:00
• 51dfd5101b Only dump packets when tracing w/RIO Jim 2011-08-16 15:31:07 -04:00
• f742bc46a9 Add code to devpnc to remember when it triggers interrupts, seems to work okay and not have the 30-second delay problem. Jim 2011-08-16 15:28:14 -04:00
• 6a668b877d Timestamp packet dumps and polls, check for interrupt needed when interrupts are enabled. This fixes the 30-second lag problem, but also causes PNCDIM to get notified too many times. After an xmit, devpnc causes an immediate interrupt. This is handled by the SEG4 phantom interrupt code by disabling PNC interrupts, then notifying PNCDIM. (Remember, PNCDIM is still in the xmit OTA, or shortly following). PNCDIM finishes its loop, enables interrupts, and does a WAIT. When it enables interrupts before the WAIT, devpnc doesn't remember that it has already interrupted, and interrupts again. I think this is a bug - the other emulator controllers have a state variable to remember whether they have already interrupted. But, if I fix this "bug", we'll probably have 30-second delays again. Hmmm... Jim 2011-08-16 14:46:36 -04:00
• 4ddd43debf Add async I/O code to devpnc, but disabled for now: there is a delay problem with remote terminal sessions: Jim 2011-08-15 17:11:28 -04:00
• e4dfa3fade Interrupt immediately after xmit and rcv instead of doing a poll. Jim 2011-08-14 23:53:12 -04:00
• b1bb5c9a3c Fixed PNCDIM halt bug (= sb == in POLL), minor cleanups Jim 2011-08-14 17:42:10 -04:00
• 479acd4788 When tracing, fatal() dumps RP instruction address queue Jim 2011-08-14 13:34:07 -04:00
• 703940e525 PNC cleanups, still halts at RCV_ERR2 in PNCDIM on node B during a directory copy from node A to a disk on node B. Jim 2011-08-14 12:10:14 -04:00
• c3ba188ae4 First "working" PNC emulation, but has circuit reset issues Jim 2011-08-13 16:13:22 -04:00
• 6348f80b5a Add "eas" trace flag to trace 32S addressing Jim 2011-08-13 16:12:33 -04:00
• 945f48057c Add multi-indirect level test for several 32R cases (64R is always single indirect) Jim 2011-08-13 11:07:37 -04:00
• 26b86c84e9 Add "off" trace option: initially disabled, ctrl-t to toggle it Jim 2011-08-13 10:58:16 -04:00
• f69f9e9696 After changing EAFA to preserve the E-bit, CPUT4 halted at 10001. In this case, bitno was specified in the EAFA instruction itself. The emulator was setting the E-bit in the returned ea because there was a non-zero bit offset. This extra test of bitno & setting of E-bit was removed from apea to pass CPUT4 at 10001. Jim 2011-08-09 09:10:55 -04:00
• f0983d6ccb Preserve fault and E bits in EAFA instructions to pass CPUT4 T&M halt at 7753 and 10061. At 7753, CPUT4 loads -1L into the SB register, EAFA 1,SB%, then LDLR '12 to get the FAR1 register value. It expects it to be -1. For the test at 10061, EAFA was clearing the E-bit in FAR1, but the test expected it to be set. The emulator never uses the E-bit in the FAR (it only looks at bitno), so it doesn't matter how the E-bit is set in the register. Jim 2011-08-09 09:04:15 -04:00
• bffaa206bf CPUT4 halt at 10203 reveals that the field length register bits 60-64 are the high-order bits of the length, not the low-order bits as I had assumed. Jim 2011-08-08 19:03:25 -04:00
• 687d068335 Default sense switches are now 0 instead of 14114 when booting from a Prime runfile, eg, T&M. Check for either CR or LF to continue after HLT. Jim 2011-08-08 09:24:17 -04:00
• 499d07d82e CPUT4 T&M: max indirect levels is 8 then RXM fault occurs (S/R mode) Jim 2011-08-06 14:44:42 -04:00
• adbf7dff22 Always print a linefeed after HLT Jim 2011-08-06 09:39:19 -04:00
• 6b080f7c5e For CPUT4, add LPID (only checks restricted) and mark some other unimplemented instructions as restricted. Jim 2011-08-06 09:30:27 -04:00
• 23b8cd9892 Only use 28 bits of physical address in mapva to correct CPUT4 emulator seg fault after LPSW near label RXM in CPUT4. Jim 2011-08-06 09:01:16 -04:00
• 8ad786dc42 Invalidate brp cache on LPSW, since segmentation could be enabled. Jim 2011-08-06 08:47:53 -04:00
• 3b6ed6f52c On HLT with -boot filename (T&M), either continue or halt. Add trace code for CLS to show memory value used for comparison. Jim 2011-08-06 08:44:36 -04:00
• 4388350678 Allow continue after HLT for -boot filename for V-mode T&Ms Jim 2011-08-03 17:31:09 -04:00
• 6beed769cf Add -trace arg (number > 99) to start tracing after this instruction. This is an unsigned int, so will overflow after 4B instructions, but it's impractical to trace that many instructions anyway. This feature is used for debugging the emulator, getting diags to work, etc., so instruction counts tend to be low. Jim 2011-08-02 16:57:10 -04:00
• 2943b41e0c Cause UII for P300 paging instructions for CPUT4 T&M Jim 2011-08-02 14:41:16 -04:00
• cefc0e64e8 Corrected CREP and RTN based on CPUT4 T&M Jim 2011-08-01 18:08:14 -04:00
• efe90b9abb Change UII fault to pass ea for faddr instead of RP, to pass CPUT1 T&M. NOTE: ea would only be set for mem. ref. instructions, but we use the same code at label d_uii: for generics too. Not sure what the ea should be for a generic UII fault where there is no ea computed. Jim 2011-07-31 23:25:51 -04:00
• 12e82b1d9a Fix bug in CEA: 16S not truncating ea after indexing. Caught by old T&M test CPUT1. Checked ea16s, and it was already doing the truncate. Jim 2011-07-31 22:54:11 -04:00
• 37909a6de0 Add sense switch skips SS1-4, SR1-4, SSS, SSR to run old T&M diags Jim 2011-07-31 22:40:33 -04:00
• 314ef7cc50 Changed -sd to -ds to specify data switches, to run old T&M programs, don't load registers and keys from the runfile unless the 'regs' option is used. Old T&M's were normally loaded into memory, followed by a master clear, then run. The Prime runfiles on disk (at rev 18) had the wrong mode in the key field of the rvec file header, so the test did not execute properly. Also expanded the boot help for data switches. Jim 2011-07-30 18:14:35 -04:00
• fde9c6e812 Initial PNC driver (no receive yet), added #ifdefs for trace, allow continuing after real HLT in S and R modes for old T&M diagnostics, expanded list of Prime device drivers Jim 2011-07-30 17:06:19 -04:00
• 6a00d0d937 Add mt option to return 2-word zero record instead of error status, to test how magrst behaves. It treats this just like a real tape error, which is good. If mtwrite is used to re-create a physical tape from a .tap file, it cannot re-create tape errors, so writes a 4-byte zero record instead. Prime magrst will still see this as an error record since it isn't long enough to be a real magsav record. Jim 2011-07-18 09:49:34 -04:00

• ba3d9a1a7f licensing, sys console, fixed rare hang in sleep if IMPS goes to zero add DNS lookup on every license server connect to handle dynamic IP made keyboard chars ^O, ^Y, and ^V work on system console added printf in fatal() if any messages were logged to error.log supports ^b in Primos II to reboot from tape w/Primos II in memory to allow running make rev 19 from Primos II, but it's still broken fixed cylinder limits for some disk models (couldn't format some drive types) fixed devdisk problem: a error on one unit could cause bogus errors on another IMPORTANT: fixed rare bug where emulator would hang in sleep (IMPS=0) Jim 2008-04-25 00:00:00 -04:00
• 1750f7f83b license dongle, boot options, amlc, tape, disk, change device filenames added licensing dongle support boot option supports filename, sense and data switches: -boot filename sswitch dswitch (for D. Boone) -ds option (like VCP) as alternate way to set data switches (for D. Boone) removed -v and -vv: they were old and didn't do anything tries to read ring0.map and ring3.map if no -map option used fixed bug with new connect for multiple AMLC controllers default build is now for 32 amlc lines fixed disk geometry for CMD; added geometry for Model 4935 (1.1G NEC) fixed tape boot for variable record sizes (for D.

• 1e85a5c348 fixed MAJOR BUG (since em83) where memory writes were being lost because the "page unmodified" bit wasn't being cleared. If Primos needed the page, it wouldn't write it to the paging disk first. Jim 2007-10-17 00:00:00 -04:00
• 3bb5eefc61 fixed multiple extension segments (stex, pcl, prtn), perf tweaks -- this was causing the LISTENER_ORDER$ signals after DIAG -- also was causing HELP to fail sporadically (HELP MTRESUME) removed TB_xxx flags (identical to T_xxx) added some eap hints changed to pop the concealed stack earlier changed LDLR/LDAR to load result from RP if ea is 7 changed STLR/STAR to store result in RP if ea is 7 added new trace flags for GET/PUT (unimplemented) Jim 2007-10-16 00:00:00 -04:00

• 399b67ea91 SSSN hack to bypass serialization in Primos, more performance tweaks changed B(I,D)(X,Y) instructions to increment/decrement inside if; (avoids reloading values to test them) and removed B(X,Y)NE macros changed default cpuid to 15 so real time clock is always set use ppa instead of ppn to avoid << 10 on every memory reference changed newkeys() so illegal keys give illegal instruction vs fatal() removed hack to patch Primos for rev 23 SSSN check added code to SSSN to skip the check loop immediately following removed #ifdef FAST from a few places, just use the faster code added code to LDA trace to also display as two octal bytes Jim 2007-09-23 00:00:00 -04:00
• 2fb2e1a348 PCL fixes, more perf tweaks: shift, prtn, add16 changed EXPCL macro to set and clear bits - not just set changed shift instructions - made CLEARCL conditional; this means keys are only updated once per shift, not twice fixed prtn to update stack free pointer after values fetched in case a fault occurs and prtn is restarted changed prtn to invalidate brp cache only if ring changes changed prtn to inline, to avoid register save/restore changed argt to only update rp word offset in sf header added hack to pcl to correct wrapped RP for cpu.pcl case 42 added cgt inline proc, used in 2 places; generates better code (store to utempa is avoided altogether) added pimh (also used for pima) inline proc to avoid stores inlined invalidate_brp changed add16 implementation while looking at code generated ran faster according to Jeff's timers: 59/52 for old/new Jim 2007-09-15 00:00:00 -04:00
• d99d16932d More performance tweeaks: get/put(16/32)r, eaxxx() changed get/put(16,32)r to check for ring change and use regular get/put call if possible, so brp supercache can be used FUTURE: could add separate brp cache entry for R0 accesses changed ea32r64r live register test so normal path is first changed ea64v live register test so normal path is first change ea32i to use INCRP macro instead of RPL++ Jim 2007-09-15 00:00:00 -04:00

• 84ae6fc905 eap register and gvp->brp page cache: 5 entries for PB, SB, LB, XB, "other" removed "char unmodified" from STLB; uses access[2] instead, to avoid a multiply instruction in mapva (can use shift now) use ea instead of pa when checking for page crossing in get32, in preparation for read VA caching, like iget16 uses Jim 2007-09-09 00:00:00 -04:00
• 98417e5835 invalidate instruction cache page (instvpn) whenever OWNER might change removed OWNER tests from instruction fetch Jim 2007-09-07 00:00:00 -04:00
• 6afd8f2c52 added inline to shift procedures (reduced the executable size, + faster) + changed gvp->prevppa from Prime memory offset to mem[] pointer added inline to tch, tcr, adlr added -DNOIDLE to make BDX use CPU cycles instead of sleeping changed ea64v.h so ixy avoids branching (hot spot in Shark) Jim 2007-09-07 00:00:00 -04:00
• 24179fd2ac added dispatch table for SRV memory references instructions vs switch + inlined and simplified iget16 instruction fetch moved pio test to R-mode path moved and simplified effective address calculation switch stmt removed mode switch stmt for EA calcs, changed to cascaded if moved iget16 static vars to gvp, for inlining changed mapva and iget16 so that the normal path is predicted Jim 2007-09-05 00:00:00 -04:00
• 31edfb6674 removed valid bit from STLB cache and use segment # 0xFFFF instead this allows removing a comparison from mapva's fast path Jim 2007-09-04 00:00:00 -04:00
• ab4316a6a8 added FAST2 #ifdef to eliminate memory limit test, simplify CAS Jim 2007-09-04 00:00:00 -04:00
• 2ee4f03291 added mapva stats Jim 2007-09-04 00:00:00 -04:00
• 8f95ccc375 FDV, DFDV, FD, DFD always test for zero divisor, const mapio, fastmap added fastmap, but it's disabled because Primos 19 won't boot made mapio a const function Jim 2007-09-04 00:00:00 -04:00
• 904ab90bd3 changed ea switch statement to multi-line if to check 64v first, get64 #FAST Jim 2007-09-03 00:00:00 -04:00
