1// nx_driver_exceed.nx -- DRIVER-EXCEEDS-LINUX measured panel (X-DRV-W3), the no-overclaim "stomp". 2// 3// AUTHOR=ORGAN, NO-WAVE: COMPUTES every panel value from REAL Nishi artifacts (never asserted), 4// and is HONEST about what is NOT apples-to-apples measurable. The Nishi emitted virtio-blk 5// driver is compared head-to-head with the generic Linux virtio-blk driver on the axes a flat 6// artifact can be MEASURED on: 7// - standalone-driver-bytes : stat the emitted image (_drv_proto_blk.bin) -- the COMPLETE driver 8// that brings the device up + does one I/O, needing NO kernel/libc/loader (it is a raw rv64 9// image: first bytes are NOT the ELF magic). Linux's virtio-blk driver is kernel-resident C 10// (not a standalone bring-up artifact). => WIN on minimal auditable TCB. 11// - driver-logic-form : the driver IS a DATA op-list spec, RE-TARGETABLE with zero recompiles 12// (X-DRV-W2 brought up N devices from registry rows, the emitter binary untouched). Linux is 13// hand-written C, a recompiled .ko per driver. => WIN on retargetable-as-data. 14// - firmware-blob-freedom : the driver spec references ZERO firmware/blob files. virtio-blk on 15// Linux is ALSO blob-free (paravirtual). => TIE (honest -- not a win for virtio). 16// - throughput / latency : NOT apples-to-apples measurable -- the Nishi driver runs on the 17// sovereign rv64 emu; there is no common substrate with a real Linux driver. => OPEN, NOT 18// CLAIMED (the no-overclaim discipline; a perf substrate is a separate future rung). 19// 20// Authors knowledge/registry/driver_exceed_panel.tsv + logs DRVEXCEED -> driver_exceed.log. 21// Sovereign (syscalls only, no gcc/.sh). license_tier: ORIGINAL 22import "nx_syscalls.nx" 23const DX_MAGIC_65536: i64 = 65536 24const DX_MAGIC_262144: i64 = 262144 25 26const DX_BLK_BIN: *u8 = "runtime/_hdl_build/_drv_proto_blk.bin" 27const DX_BLK_SPEC: *u8 = "knowledge/specs/drv_proto_blk_virt.spec" 28const DX_BIND_LOG: *u8 = "knowledge/status/driver_bind.log" 29const DX_PANEL: *u8 = "knowledge/registry/driver_exceed_panel.tsv" 30const DX_LOG: *u8 = "knowledge/status/driver_exceed.log" 31 32func dx_p(s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} sys_write(1,s,n); return 0 } 33func dx_fp(fd: i64, s: *u8) -> i64 { var n: i64=0; while s[n]!=(0 as u8){n=n+1} sys_write(fd,s,n); return 0 } 34func dx_fn(fd: i64, v: i64) -> i64 { let bb: *u8=sys_mmap(28); var m: i64=v; if m<0{m=0-m}; let t: *u8=sys_mmap(28); var k: i64=0; if m==0{t[0]=48;k=1}; while m>0{t[k]=(48+(m%10)) as u8;m=m/10;k=k+1}; var i: i64=0; while i<k{bb[i]=t[k-1-i];i=i+1}; sys_write(fd,bb,k); return 0 } 35 36func dx_read(path: *u8, buf: *u8, cap: i64) -> i64 { 37 let fd: i64 = sys_openat_rd(path) 38 if fd < 0 { return 0 - 1 } 39 var n: i64 = 0 40 var go: i64 = 1 41 while go == 1 { let r: i64 = sys_read(fd, (buf as i64 + n) as *u8, cap - 1 - n); if r <= 0 { go = 0 } else { n = n + r } if n >= cap - 1 { go = 0 } } 42 sys_close(fd) 43 return n 44} 45 46// count non-overlapping occurrences of pat in buf[0,n). 47func dx_count(buf: *u8, n: i64, pat: *u8, pl: i64) -> i64 { 48 if pl <= 0 { return 0 } 49 var c: i64 = 0 50 var i: i64 = 0 51 while i + pl <= n { 52 var k: i64 = 0; var hit: i64 = 1 53 while k < pl { if buf[i+k] != pat[k] { hit = 0; k = pl } else { k = k + 1 } } 54 if hit == 1 { c = c + 1; i = i + pl } else { i = i + 1 } 55 } 56 return c 57} 58func dx_has(buf: *u8, n: i64, pat: *u8, pl: i64) -> i64 { if dx_count(buf,n,pat,pl) > 0 { return 1 } return 0 } 59 60// count "op " lines (the driver state-machine steps) in the spec: leading "op " or "\nop ". 61func dx_count_ops(buf: *u8, n: i64) -> i64 { 62 var c: i64 = 0 63 var i: i64 = 0 64 while i < n { 65 var at_line: i64 = 0 66 if i == 0 { at_line = 1 } else { if buf[i-1] == (10 as u8) { at_line = 1 } } 67 if at_line == 1 { 68 if i + 3 <= n { if buf[i] == (111 as u8) { if buf[i+1] == (112 as u8) { if buf[i+2] == (32 as u8) { c = c + 1 } } } } // "op " 69 } 70 i = i + 1 71 } 72 return c 73} 74 75func main() -> i64 { 76 dx_p("=== nx_driver_exceed: measured no-overclaim driver-exceed panel (X-DRV-W3) ===\n" as *u8) 77 78 // ---- MEASURE from real artifacts ---- 79 let imgbuf: *u8 = sys_mmap(DX_MAGIC_65536) 80 let nbytes: i64 = dx_read(DX_BLK_BIN, imgbuf, DX_MAGIC_65536) // standalone driver bytes (stat) 81 var raw_image: i64 = 0 // 1 = not an ELF (no loader/libc) 82 if nbytes >= 4 { if imgbuf[0] != (127 as u8) { raw_image = 1 } else { if imgbuf[1] != (69 as u8) { raw_image = 1 } } } 83 84 let specbuf: *u8 = sys_mmap(DX_MAGIC_65536) 85 let specn: i64 = dx_read(DX_BLK_SPEC, specbuf, DX_MAGIC_65536) 86 let nops: i64 = dx_count_ops(specbuf, specn) // driver state-machine steps (data) 87 var nblob: i64 = 0 // firmware/blob refs in the spec 88 nblob = nblob + dx_count(specbuf, specn, "firmware" as *u8, 8) 89 nblob = nblob + dx_count(specbuf, specn, "blob" as *u8, 4) 90 91 let logbuf: *u8 = sys_mmap(DX_MAGIC_262144) 92 let logn: i64 = dx_read(DX_BIND_LOG, logbuf, DX_MAGIC_262144) 93 let retarget: i64 = dx_has(logbuf, logn, "bound_working=2" as *u8, 15) // W2 evidence: 2 devices, 0 recompiles 94 95 if nbytes <= 0 { dx_p("DRVEXCEED verdict=RED reason=blk-image-missing (run nx_drv_proto_emit first)\n" as *u8); let lf0: i64 = sys_openat_append(DX_LOG, 0x1a4); if lf0>=0 { dx_fp(lf0,"DRVEXCEED verdict=RED reason=blk-image-missing\n" as *u8); sys_close(lf0) } sys_exit(1); return 1 } 96 97 // ---- AUTHOR the panel (every value above is MEASURED) ---- 98 let ofd: i64 = sys_openat_wr(DX_PANEL, 0x1a4) 99 if ofd < 0 { dx_p("DRVEXCEED verdict=RED reason=panel-unwritable\n" as *u8); sys_exit(1); return 1 } 100 dx_fp(ofd, "# driver_exceed_panel.tsv -- AUTHORED BY nx_driver_exceed (X-DRV-W3).
