In struct tme_sjlj_thread, added the last dispatch + number for a thread, and under HAVE_GTK, no longer track timeout + handles. Removed tme_sjlj_thread_dispatched_timeout. Define globals + for the global dispatch number, the reasonably current time, and the + short thread flag.

Now use TME_SPARC_HAVE_RECODE() to test for + recode support. Reworked idle handling. Now, an idle type must mark + two consecutive idles without a trap before we go idle.

We now use the ic's actual page size + everywhere, instead of a fixed sparc recode page size. The fixed + sparc recode page size of 4KB forced writes to always be assisted when + the ic had a larger page size, because DTLB entries for writing were + never for a full page (since we made the fixed sparc recode page size + the validity size for cacheable memory, DTLB entries were never bigger + than that). All users changed. Moved _tme_sparc_recode_verify_on + from sparc-rc-verify.c, and added _tme_sparc_recode_off. + Added sparc-rc-ls.c to the set of recode parts included for each + architecture. + Now define TME_SPARC_RECODE_RW_THUNK_INDEX(). + (tme_sparc_recode): If recode is off, return immediately. + (tme_sparc_recode_dump_insns): Added support for read/write + instructions. + (tme_sparc_recode_init): Allocate and initialize the read-uses + records. On a v9 CPU, %r1 through %r7 are addressed through recode + register window two. Set all of the recode TLB entry information for + read/write instructions. Call the architecture-specific + initialization for loads and stores. + + * ic/sparc/stp103x.c: Now define TME_STP103X_ICACHE_BLOCK_SIZE. + Reorganized struct tme_stp103x slightly, to put everything that is + recode-verifiable first, and everything that is accessed by loads and + stores last. + (_tme_stp103x_interrupt_check): + (_tme_stp103x_flush): If we're replaying instructions, return + immediately. + (_tme_stp103x_update_pstate): Fixed a bug where we wouldn't update the + recode register window offsets. + (_tme_stp103x_rdpr): Added. + (_TME_SPARC_EXECUTE_OPMAP): Now use _tme_stp103x_rdpr. + (_tme_stp103x_ls_cycle_block_ld): + (_tme_stp103x_ls_cycle_block_st): Save the block for verification. + (_tme_stp103x_new): Fixed a bug where we were only allocating a struct + tme_sparc, and not the larger struct tme_stp103x. Initialize + _tme_sparc_ls_asi_misaligned. Under _TME_SPARC_RECODE_VERIFY, + initialize the recode verify sizes. + + * ic/stp22xx/stp220x.c: + * ic/stp22xx/stp222x-main.c: Removed some AUDITs. + + * libtme/host/x86/rc-x86-rws.c: Fixed various bugs where we used a + size with a TME_RECODE_X86_REX_B() that is for addressing. + (_tme_recode_x86_rw_tlb_ref): Fixed a bad assert(). + (tme_recode_host_rw_thunk_new): Added support for recode TLB entries + with a 16-bit context. + Added support for offsetting the address when making the TLB entry + index. + The recode TLB entries are now a found directly in the ic structure, + not found through a pointer. + Now emit instructions to check a recode TLB entry's context. Fixed + bugs where we would emit a displacement-less EA when the lone base + register is %bp or %r13. + In the double-host-size most-signficant write, we know that its size + is TME_RECODE_SIZE_HOST. + Fixed a bug where we wouldn't do the double-host-size most-significant + read first, before we destroy the host memory address register. Fixed + bugs where we would lose instructions because we forgot to finish and + restart the thunk, or forgot to advance thunk_bytes. + +Mon Aug 31 02:23:41 2009 Matt Fredette + + * ic/sparc/sparc-rc-ls.c (TME_SPARC_RECODE_RW_FLAG): Removed. + (_tme_sparc_recode_ls_assist_check): Added. + (_tme_sparc_recode_ls_assist_ld) [_TME_SPARC_RECODE_VERIFY]: + (_tme_sparc_recode_ls_assist_st) [_TME_SPARC_RECODE_VERIFY]: Call + _tme_sparc_recode_ls_assist_check(). + (tme_sparc_recode_ls_tlb_update): Now take the struct tme_sparc_ls *, + so we can get the DTLB entry directly. Added tme_sparc_ireg_t casts + to the DTLB address check, to avoid doing math in a wider + tme_bus_addr_t. + Force assists for a DTLB entry if it uses special ASIs. + Improved the recode TLB entry read/write flags, including handling + DTLB entries for no-fault loads, addresses with side-effects, and + endianness changes. Also, no longer check for DTLB entries that + support the secondary address space, because we can't assist them + (mostly because recode read/write instructions only have a single + default context). + All sparc recode TLB entries have a 16-bit context, and update the + context and the context mismatch read/write flag as needed. + (_tme_sparc_recode_ls_init): Improved how the read/write thunks are + generated, and especially their read/write flags masks. No longer + make read/write thunks for accesses to secondary address spaces. Make + read/write thunks for no-fault loads. + + * ic/sparc/sparc-rc-verify.c: Define a token for the replay ITLB + entry. + (tme_sparc_recode_verify_begin): Set the token on the replay ITLB + entry. + (_tme_sparc_recode_verify_init): Initialize the token for the replay + ITLB entry, and mark it as valid. + +Mon Aug 31 01:58:38 2009 Matt Fredette + + * generic/fb-xlat-auto.sh: Now only check framebuffer contents that + may have been updated for changes. + + * host/gtk/gtk-screen.c (_tme_gtk_screen_th_update): If the + framebuffer needs a full redraw, force the next translation to + retranslate everything. + (_tme_gtk_screen_mode_change): Now delay forcing the next translation + until the next screen update. + + * host/posix/posix-memory.c: Defined some macros for sizes of + cacheables, and the writable TLB entry hash set. + Added struct tme_posix_memory_valids. In struct tme_posix_memory, + added a mutex. Fixed a bug where the rwlock was a mutex. Added + pointers to any writable TLB entry hash set, a list of valids + bitmasks. Added members for the current writable TLB size, and our + cacheable structure. + (_tme_posix_memory_tlbs_invalidate): Added. + (_tme_posix_memory_tlb_fill): If this memory is cacheable, return the + cacheable structure in the TLB entry, and if this is a write, track + the TLB entry in the hash set and clear the bit for the address' page + in all valids bitmasks. + (_tme_posix_memory_valids_new): + (_tme_posix_memory_valids_set): Added. + (tme_host_posix,memory): If the memory is cacheable, allocate the + writable TLB entry set, initialize the valids list and the writable + TLB size, and the cacheable structure. + + * ic/sparc/sparc-execute.c: Now define TME_PRIxSPARCREG. + On sparc64, fixed the ASI mask code and set the default memory + context. + [TME_HAVE_RECODE]: Set the default read/write flags for the current + CPU state. + Instead of constructing the invalid ITLB entry, initialize its new + token and set it on the entry. Never acquire the external mutex, and + only call the external check function if the external flag is set. + Now save the previous PC. If we're replaying recoded instructions for + the verifier, stop replaying if the previous PC was the last to + replay. Otherwise, poison it to prevent all recoding. Added + (tme_sparc_ireg_t) casts to the ITLB entry address checks, to avoid + doing math in a wider tme_bus_addr_t. Now use TME_SPARC_TLB_HASH() + and TME_SPARC_ITLB_ENTRY() to get the ITLB entry from the array. Now + check the context on an ITLB entry. Now, instead of filling the ITLB + entry ourselves, just do a slow load of the instruction, which will + take care of everything, including fetching the instruction into the + memory buffer if needed. Since idle loop detection can't take place + in the instruction executor when recode is in use, moved the + netbsd32-type-0 detection into tme_sparc32_wrpsr(). In the rare case + that an annulled instruction is also a branch target + (which can only happen if there are two branches in a row, where the + second one annuls), make sure we don't try to recode starting at the + annulled instruction. + Use TME_SPARC_G0_OFFSET(ic) to find the globals. + [TME_HAVE_RECODE]: Now recode instructions, run recoded instructions + thunks, and replay the same instructions through the normal executor + to compare the effects. + TME_SPARC_IREG_IMM has been replaced by TME_SPARC_IREG_TMP(0). Added + support for the sparc64 format two instructions. Added support for + the sparc64 %pstate.AM in the control transfers. + + * ic/sparc/sparc-insns-auto.sh: Define _tme_sparc_float_null. + Now emit the fpop1 and fpop2 instructions.

If this ASI has a special + handler, force a slow load or store by making the ASI mask undefined. + (_tme_sparc64_alternate_asi_mask): + (_tme_sparc${arch}_fpu_mem_fpreg): Added. + (tme_sparc${arch}_udiv): + (tme_sparc${arch}_udivcc): + (tme_sparc${arch}_sdiv): + (tme_sparc${arch}_sdivcc): Trap on division by zero, and added + overflow handling for the cc instructions. Fixed a sparc64 bug where + we would only set %icc.Z when the 64-bit result was zero. + In the load/store instructions, get the right address for the sparc64 + casa and casxa instructions, and when %pstate.AM is set. Get the + context for sparc64 alternate instructions. Make a mask of ASI flags + that will trigger a slow load/store. Check the DTLB entry's context. + Added (tme_bus_addr${arch}_t) casts to the DTLB address check. Check + that the ASI mask in the DTLB entry allows fast transfers. For a slow + transfer, call the new tme_sparc${arch}_ls(). Now, allow the slow + function to complete an alternate load. Get the byte order of the + access and do byteswapping as needed. + (tme_sparc${arch}_${insn}): Added support for the sparc64 %pstate.AM + and possible address space hole. + (tme_sparc${arch}_ldf*): + (tme_sparc${arch}_stf*): On sparc64, call the ASI misaligned function + to see if the address is misaligned. Before the memory access, now + call _tme_sparc${arch}_fpu_mem_fpreg() to check for any traps and to + get the floating-point register. + (tme_sparc${arch}_lddf*): + (tme_sparc${arch}_stdf*): On sparc64, call the ASI misaligned function + to see if the address is misaligned. Before the memory access, now + call _tme_sparc${arch}_fpu_mem_fpreg() to check for any traps and to + get the floating-point register. Added support for sparc64 + fully-aligned and 32-bit aligned accesses. + (tme_sparc${arch}_ldfsr): + (tme_sparc${arch}_stfsr): Now check for traps with + _tme_sparc${arch}_fpu_mem(). Added support for the sparc64 ldxfsr and + stxfsr. + (tme_sparc${arch}_atomic): Added. + (tme_sparc${arch}_load): + (tme_sparc${arch}_store): These functions are no longer called + directly by instruction functions. They now only do final loads and + stores (as opposed to pre-access fault checking, DTLB filling, etc.). + (tme_sparc${arch}_ls): Added. This is the function called by + instruction functions to do a slow access. This coordinates special + ASIs, address mapping, DTLB filling, pre-access fault checking, and + slow load, store, and atomic cycles. + + * ic/sparc/sparc-misc-auto.sh: Define the sparc64 alternate, MMU, and + interrupt globals.

Defined many + sparc64 architected and internal registers. + + * ic/sparc/sparc-misc.c (_tme_sparc_bus_signal): Now recognize the bus + grant signal. Now track both assertion and negation of halt and + reset. Changed the external signal indications to true atomic flags, + and set the external atomic flag after any changes. Moved the + condition variable notify inside the mutex lock. + (_tme_sparc_bus_interrupt): Now update the external IPL value with an + atomic write, and set the external atomic flag afterwards. Moved the + condition variable notify inside the mutex lock. + (tme_sparc_idle): Now call the ic-specific external check function, + instead of the_sparc32_external_check(). + (tme_sparc_thread): Added support for TME_SPARC_MODE_OFF. + (_tme_sparc_generic_tlb_fill): Now take a tme_bus_addr_t. Don't set + the ASI mask any more, the slow load/store function has arranged or + will arrange for it to be set. + (_tme_sparc_connection_score): + (_tme_sparc_connections_new): Replaced bus connection TLB set allocate + references with TLB set add references. Added support for UPA bus + connections. + (_tme_sparc_connection_make): Replaced bus connection TLB set allocate + references with TLB set add references. Added support for UPA bus + connections. Now initialize the TLB set and add it to the bus, + getting the maximum context back in the v7 case. + (tme_sparc_new): Added support for the tick-frequency and + prom-delay-factor options.

Added support for the v9 ld*a + instructions, because they may be used for speculative loads, which we + do want to handle with recode read instructions. + For BPcc and Bicc, extract the branch displacement using 32-bit types + for as long as possible. Now test TME_SPARC_RECODE_INSN_UPDATE_INSN + to see if an instruction always or sometimes needs an assist, instead + of just checking for TME_RECODE_OPCODE_GUEST. + Fixed a bug in the v9 32-bit shifts where we put the extension source + size in the immediate field, instead of the second source operand + field. + Reused the old TME_SPARC_RECODE_INSN_STORE support for generating an + assisted store for generating recode read/write instructions. + +Sun Aug 30 17:06:38 2009 Matt Fredette + + * ic/sparc/sparc-fpu-auto.sh (_tme_sparc_fpu_fcc_${precision}): Added + support for the additional fccN on sparc64. + (tme_sparc_fpu_fpop[12]): Added support for encoded floating-point + register numbers, recode verification, FMOV*cc, FxTO*, F*TOx, FNEGd, + FABSd.

For those trap names that are + common across architectures, a new TME_SPARC_TRAP() macro can be used + to expand to the right value for the current architecture. All users + changed. For sparc64, added the FPRS, TSTATE, WSTATE, VER, XCC, and + VIS GSR fields, and added more PSTATE fields. Added the sparc VIS + ASIs. + Added macros for the SPARC integer conditions. Added + TME_SPARC_MODE_OFF and TME_SPARC_TL_MAX. Added a set of macros for + updating the register window offsets for a new CWP, that update + separate offsets for the output, local, and input registers, and also + the recode register window offsets. This simplifies + TME_SPARC_REG_INDEX. Now that there are only flat DTLB and ITLB + arrays, added a TME_SPARC_TLB_HASH() to hash an address into an array. + TME_SPARC_DTLB_ENTRY() and TME_SPARC_ITLB_ENTRY() now take one of + these hashes, instead of an address. The slow load and store + functions, and any function that supports a slow load or store, now + take an expanded set of information about the access. + Added macros for defining masks of load/store faults and memory + features. + Now define TME_SPARC_FPU_FPREG_NUMBER_UNDEF, TME_SPARC_FPU_DIRTY(), + and TME_SPARC_FPU_IS_DISABLED().

In struct + tme_sparc, added the cycles scaling, replaced the single CWP offset + with individual offsets for the global, output, local, and input + registers. Added members for sparc64. Expanded the + implementation-dependent data and functions, especially for the new + load/store architecture. Retyped the instruction burst counters as + tme_uint32_t, since recode requires that. Replaced the old TLB entry + set pointers with a single sparc TLB entry array and a complementary + array of tokens or recode TLB entries. Added per-ASI information, and + members for memory context. Added members for the new bus external + interface. Changed the memory buffer to be a union of all of the + integral types. Expanded the number of FPU registers and added the + sparc64 XFSR. Added the VIS state. Fixed a bug where the sparc64 + idle PC was a tme_uint32_t. Under [TME_HAVE_RECODE], added all of the + state needed for sparc recode. Added more statistics.

Removed the TME_ATOMIC_ set + of macros, which may or may not use a rwlock to serialize access to + a value, and added the tme_memory_atomic_ set of macros, which + always requires an rwlock argument. + This tme_memory_atomic_ set of macros also takes a compile-time + minimum alignment hint, covers a wide range of math operations, and + is guaranteed to work atomically for any access, no matter what the + actual alignment. + Added the tme_memory_bus_ set of macros, which work just like the + tme_memory_atomic_ macros but only within a certain bus size - i.e., + if a 32-bit bus size is specified, and an access crosses one + 32-bit-aligned address boundary, the access will be split into two + atomic accesses. + The tme_memory_atomic_ and tme_memory_bus_ macros should better + enable emulation on a non-cooperative threading host someday. Added + the tme_memory_ set of macros, which don't access memory atomically + but still take the same compile-time minimum-alignment hint and are + guaranteed to work for any actual alignment. This has caused + significant fallout in all TLB handling, since the first and last + address fields in a TLB were previously TME_ATOMICs, and TLBs were + invalidated by atomically updating these first to be greater than + last. + This method would not have worked in a non-cooperative threading + host. First, it was impossible to update both first and last + address fields simultaneously, and second, it was impossible to know + if anyone was using, or had committed to using, the TLB while you + were invalidating it. Without knowing that the TLB can't be used + after invalidation, the invalidator can't continue and make other + changes that would give incorrect behavior if the TLB *is* actually + used later. + So, TLBs have a new discipline. They have "busy" and "invalid" + atomic flags. Before a TLB entry is used, its busy flag is marked + true, and its invalid flag is checked. If the invalid flag is true, + the TLB is unbusied and prepared for filling (see + tme_bus_tlb_unbusy_fill() and tme_bus_tlb_invalidate() for how they + synchronize and avoid interesting races), otherwise the TLB entry is + valid and won't be invalidated until its busy flag is set to false. + To make this truly thread-safe, someday all slow bus cycle handlers + will have to take a TLB entry somehow, so they can correctly busy + the TLB entry before making the access. + + * generic/ethernet.c generic/keyboard.c generic/mouse.c + libtme/element.c scsi/acb4000.c serial/serial-kb.c: + + Now explicitly include errno.h. + + * host/bsd/bsd-bpf.c host/posix/posix-tape.c serial/serial-kb.h + serial/serial-ms.h tme/scsi/scsi-device.h: + + Now explicitly include tme/threads.h. + + * ic/mk48txx.c ic/sparc/Makefile.am ic/sparc/cy7c601.c + ic/sparc/mb86900.c ic/sparc/sparc-bus-auto.sh + ic/sparc/sparc-execute.c ic/sparc/sparc-fpu-auto.sh + ic/sparc/sparc-fpu.c ic/sparc/sparc-impl.h + ic/sparc/sparc-insns-auto.sh ic/sparc/sparc-insns.c + ic/sparc/sparc-misc-auto.sh ic/sparc/sparc-misc.c + machine/sun4/Makefile.am machine/sun4/SUN4-75 + machine/sun4/sun4-impl.h machine/sun4/sun4-mainbus.c + machine/sun4/sun4-timer.c machine/sun4/sun44c-cache.c + machine/sun4/sun44c-control.c machine/sun4/sun44c-memerr.c + machine/sun4/sun44c-mmu.c serial/serial-sink.c tme/ic/mk48txx.h + tme/ic/sparc.h: + + Added. + + * machine/sun3/sun3-mainbus.c (_tme_sun3_command): Fixed a bug where + we wouldn't reset the VME bus. + + * tme/atomics.h: Removed. + +Sun Dec 04 22:53:37 2005 Matthew Fredette + + * ic/ncr5380.c: Fixed a bug in the TME_NCR5380_REG_PUT macro. + (_tme_ncr5380_reg_put): Now declared static. + (_tme_ncr5380_callout): Fixed a comment.

Also, each CPU uses the previous CPU's + opcode initialization function to initialize the bulk of its opcode + map, making changes only as needed. + All of this has reduced the size of the opcode map source file + dramatically. + Also, support for 16-bit immediates, sign-extended to 32 bits, has + been added again. + +Tue Mar 15 02:56:58 2005 Matthew Fredette + + * ic/m68k/m6888x.c (tme_m68k_fbcc): All 16-bit immediates are now + sign-extended to 32-bits in a fixed immediate register. + + * ic/m68k/m68k-insns.c (_tme_m68k_bcc): + (tme_m68k_bccl): + (_tme_m68k_bsr): + (tme_m68k_bsrl): Added. + (tme_m68k_bcc): Now just use _tme_m68k_bcc. + (tme_m68k_bsr): Now just use _tme_m68k_bsr. + (tme_m68k_link): Now handle the 16-bit variant explicitly. + (tme_m68k_rtd): Now handle our 16-bit argument correctly. + (tme_m68k_mull): + (tme_m68k_divl): Added. + +Thu Mar 10 13:29:42 2005 Matthew Fredette + + * ic/m68k/m68010.c: Now define _TME_M68K_EXECUTE_OPMAP to + tme_m68k_opcodes_m68010 when compiling the executors. + TME_ELEMENT_X_NEW_DECL(tme_ic_,m68k,m68010): No longer call + _tme_m68010_decoder_map_init(). + + * ic/m68k/m68020.c: Now define _TME_M68K_EXECUTE_OPMAP to + tme_m68k_opcodes_m68020 when compiling the executors. + TME_ELEMENT_X_NEW_DECL(tme_ic_,m68k,m68020): No longer call + _tme_m68020_decoder_map_init(). + + * ic/m68k/m68k-insns-auto.sh: cas2 now gets its specop2 as a 16-bit + operand. moves now must do its own memory cycles, and EA + postincrement and predecrement. + Now track memory statistics in the memory functions. + + * ic/m68k/m68k-iset.txt: Many simplifications, and some expansions, to + enable faster instruction dispatching.

Every bus should support multiple device-specific bus + signals sets, added by elements connecting to the bus. This enables + elements to pass these device-specific bus signals to each other. + Now bus signals are only specified as either asserted or negated, + and devices almost never signal edges. For devices that only drive + signals either high or low, you can exclusive-or + TME_BUS_SIGNAL_LEVEL_ASSERTED with either TME_BUS_SIGNAL_LEVEL_HIGH + or TME_BUS_SIGNAL_LEVEL_LOW as appropriate, and provide that to the + device such that the device only needs to exclusive-or that with the + signal level to get the right asserted or negated level.

This prevents the case where a device tries + to fill the same backing TLB entry at the same time in two or more + threads. TLB fill functions for devices that need to invalidate + outstanding TLBs always invalidate the backing TLB entry. After a + TLB fill has finished, the caller checks its reservation on the + real, backing TLB, and copies the local TLB back if the reservation + has not been broken. Devices that want to use a TLB entry + immediately after the fill function returns must use the local TLB, + since it cannot have been invalidated yet. Also made fixes to TLB + entry users that avoid rereading fields that are destroyed by + invalidation, after the device has committed to using the TLB entry, + since invalidation can happen at any time.
