Anns an dealbh, bidh an kernel Linux a’ cur beannachdan thugad tro GPIO.
Anns a’ phàirt seo den sgeulachd mu bhith a’ giùlain an RISC-V RocketChip gu bòrd Sìneach le Cyclone IV, bidh sinn fhathast a’ ruith Linux, agus cuideachd ag ionnsachadh mar a rèiticheas sinn rianadair cuimhne IP Core sinn fhìn agus beagan deasaich sinn tuairisgeul DTS air an uidheamachd. Tha an artaigil seo a’ leantainn , ach, eu-coltach ris an fhear a bha gu math farsaing roimhe, bidh e gu math goirid.
… Air sgàth an setup_smp ris an canar a-mhàin ma tha an kernel air a rèiteachadh le taic SMP, faodaidh tu feuchainn ri ioma-cridhe a dhì-chomasachadh. Bidh e mì-thlachdmhor ma dh’ fheumas mi cuideachd taic atomicity a chuir an gnìomh anns a ’mhodal cuimhne (bha e coltach rium gu robh an tasgadan a’ tinkers leis fhèin), ach anns a ’chùis aon-chridhe cha bu chòir dha a bhith a’ cur bacadh oirnn.
Cha do dh'fhàg e fhathast ...

...Tha e inntinneach, às deidh a h-uile càil debugging, gun do chuir mi romhpa coimhead air cò ris a bu chòir an toradh kernel “iomradh” a bhith coltach, thuirt e make qemu, agus chunnaic e mearachd coltach ris.
Gu mì-fhortanach, tha an ath ìre (Linux kernel) nas toinnte: tha e coltach gu bheil GDB, ceangailte tro JTAG ris an RocketChip, ag obair le seòlaidhean fiosaigeach ge bith ciamar a tha am MMU air a rèiteachadh, agus tha an kernel aig a bheil ùidh againn an-dràsta air an taisbeanadh a rèiteachadh. de sheòlaidhean, mar sin tha e furasta a ràdh display/10i $pc chan obraich e a-mach - chan fhaic sinn ach tòrr unimp.

O tha, ma thachras tu ag ràdh s no n an àite si, feuchaidh gdb ri briseadh inntinneach a chuir a-steach, nach tèid airson adhbharan follaiseach a shuidheachadh, ach chan eil dòigh ann air GDB a chuir às. Ach na dèan cabhag gus am bòrd ath-thòiseachadh - a rèir mo bheachdan, tha e gu leòr dìreach gdb ath-thòiseachadh (thoir an aire gur dòcha nach tèid na seann phuingean briste à sealladh).
Gu fìrinneach, feumaidh tu dèiligeadh ris an duilgheadas tùsail: suidheachadh debugging printk a-steach gu gnìomh of_find_node_by_type, air a chleachdadh le còd sgrùdaidh kernel pròiseasar boot, a’ sealltainn gu bheil e a ’faicinn seòrsa de sgudal an àite ainmean seòrsa inneal. Mar eisimpleir, bheir e an loidhne “Sreath port” bho àiteigin, ged a tha e soilleir nach eil seo anns an raon dtb device_type. Às deidh dhomh na bytes sin a lorg anns an ìomhaigh kernel, lorg mi iad, choimhead mi air an chothromachadh, agus thuig mi na tha follaiseach: tha e soilleir gu bheil meud an kernel ann am paramadairean bròg air a dhì-meas: tha e air a riarachadh 8Mb, ach bheir e suas barrachd air deich. Thug mi seachad 16Mb, ach cha do stad an neònachas. An dèidh dannsadh le leughadh FDT bho sheòlaidhean eadar-dhealaichte (mar as trice tha an seòladh air a ghluasad chun an kernel sa chlàr a1), Cho-dhùin mi mu dheireadh lorg a dhèanamh, ach dè сейчас tha e air a pharsadh an sin. Gu fortanach, an àite a bhith a 'coiseachd mun cuairt le debugger (agus tha sinn a' cuimhneachadh gu bheil nuances ann le eadar-theangachadh seòladh a dh'fheumas a bhith air am fuasgladh fhathast ann an dòigh no dhà), faodaidh tu dìreach agus crutch san fhaidhle drivers/of/fdt.c comharrachadh #define pr_debug printk.

Rè a’ phròiseas dì-bhugachaidh, thuig mi nach b’ urrainn do BBL an seòladh “dùbailte” a leughadh, chan ann air sgàth gu robh mearachd anns an rèiteachadh, ach dìreach air sgàth gu robh an nòta freumha aig an #address-cells = <1>; #size-cells = <1>;.
Le bhith a’ leudachadh toradh an deasbaid, chunnaic mi sin a’ comharrachadh type и name “air a bhualadh”, agus ann an dòigh caran neònach: chaidh a’ chiad byte aca (a’ tòiseachadh bho neoni) ath-shuidheachadh gu neoni, rudeigin mar 0xabcdef -> 0xab00ef. B’ fheudar dhomh innleachd eòlach a chleachdadh: le eòlas air na seòlaidhean far a bheil a’ chuimhne millte suidhichte, cuir ris a’ ghnìomh e printk clò-bhuail an dàta seo. Uill, na dùbhlain fhèin printk sgap iad far am bheil beagan diubh. Och, chan eil e air fàs mòran nas soilleire. An uairsin thòisich mi, a 'co-chomhairleachadh ris an fheadhainn a chaidh a chuir às a chèile objdump dreach, suidhich puingean brisidh le làimh agus gabh tron earrann trioblaideach den chòd ceum air cheum. Agus an uairsin chaidh rud dìomhair agus mì-thlachdmhor a lorg: ma shuidhicheas mi sa bhad àite briste an àiteigin gu math fada bhon t-suidheachadh aithnichte, an uairsin, a’ stad air, chì mi a’ chuimhne a tha air a mhilleadh mar-thà. Ach ma dh’ fheuchas tu ri sreap suas oirre ceum air cheum, thèid aig a’ bhiast air falach! Bidh fàileadh mar rianadair cuimhne briste agus tasgadan a bhios a’ falach na mearachd ma dh’ iarras tu an-còmhnaidh an luach a tha a dhìth. Dè ma tha…
Cuimhne a chur an àite
A’ cumail ris a’ chothrom fuasgladh fhaighinn air duilgheadas nach robh air mo thaobh, ghabh mi ris gur dòcha gu robh mi dìreach air bata cuimhne briste fhaighinn. An uairsin chuimhnich mi nach e a-mhàin coimpiutair so-ghiùlain a th’ ann an leabhar-lìn deich bliadhna a dh'aois, ach cuideachd stòr luachmhor de DDR2 SO-DIMM. Mar bhuannachd, faodaidh tu cuimhne a thoirt air falbh bhon bhòrd a chuir a-steach agus toirt air Memtest a chrochadh cha mhòr sa bhad (Linux, leis an t-slighe, air a luchdachadh cha mhòr chun t-slige grafaigeach. Ach tha e nas fheàrr gun a bhith ag ath-aithris an deuchainn seo ma tha thu a’ cur luach air an fhiosrachadh air diosgan air an cur suas ...). Air an aon làimh, faodaidh sinn a bhith den bheachd nach robh a’ chuimhne dìreach a’ freagairt air an lìon shònraichte seo. Air an làimh eile, bha e comasach dha bròg! Bha dòchas ann gun robh a’ chuimhne dìreach “briste”, agus cha robh an duilgheadas anns a’ phasgan agam.
Tha seo a’ ciallachadh gum feum thu feuchainn ri cur air bhog airson ùine le cuimhne netbook. Gu mì-fhortanach, chan eil fios aig Quartus 18 mar a nì thu ùrachadh air an IP Core seo gus an tèid a dheasachadh. Tha seo a’ ciallachadh gu bheil an t-àm ann mu dheireadh ionnsachadh mar a chruthaicheas tu suidheachaidhean ùra. Thionndaidh a h-uile càil a-mach gu bhith gu math sìmplidh: bidh sinn a ’coimhead anns a’ Chatalog IP airson an rud Rianadair DDR2 SDRAM le ALTMEMPHY Intel FPGA IP agus gheibh sinn bloc leis an aon eadar-aghaidh agus roimhe. Is e an aon dhuilgheadas a bhith a’ suidheachadh nan roghainnean cuimhne ceart.
A 'faighinn crìochan a' mhodal cuimhne
Tha dòigh gu math follaiseach ann airson am modal a rèiteachadh: leugh na paramadairean bhon SPD. Gu dearbh, ma leughas coimpiutair àbhaisteach dàta SPD agus ma rèiticheas e an rianadair stèidhichte air, an uairsin thoir air falbh an dàta seo air netbook a tha ann mu thràth agus cuir a-steach e ann an clàr.
Tha seo ga dhèanamh air Ubuntu : feumaidh tu am pasgan a stàladh i2c-tools, luchdaich modalan eeprom и i2c-i801 (Chan eil mi cinnteach, ge-tà, an obraich an dàrna draibhear anns a h-uile àite), ruith an uairsin decode-dimms:

Na tha sgrìobhte air na modalan againn:
Anns a 'chùis seo, tha an sgrìobhadh air na sgoltagan cuimhne fhèin nas inntinniche: K4T1G164QQ-HCF7. Le bhith a’ taipeadh na loidhne seo a-steach do Google, bidh sinn a’ faighinn bileag-dàta de ghrunn dhusan duilleag leis na paramadairean riatanach uile, a dh’ fhaodar a ghabhail a-steach gu sgiobalta ann an togalaichean IP Core. Dìreach thoir aire do na h-aonadan tomhais: an àiteigin ns, àiteigin - ps, agus uaireannan eadhon earrannan tCK. Cha bhith mi a’ teagasg dhut dè a bu chòir dhut aire a thoirt - shuidhich mi tòrr rudan mi-fhìn air thuaiream (chan urrainn dhomh gealltainn nach urrainn dhut an cuimhne no FPGA a “losgadh” san dòigh seo). Bidh mi dìreach a’ tarraing d’ aire gu seo: cha b’ urrainn dhomh an rianadair a bhith ag obair airson ùine mhòr, agus b’ e an ceum mu dheireadh a bhith a’ tuigsinn gum feumadh mi sgrùdadh a dhèanamh air leud gach eadar-aghaidh cuimhne airson gèilleadh ris a’ chòd Verilog a chaidh a chruthachadh. : às dèidh a h-uile, nuair a-staigh MemIfBundle air a chomharrachadh val mem_ba = IO(Output(UInt(2.W))), agus tha 8 bancaichean ann (ie seòladh 3 pìosan de leud), agus an uairsin chan eil againn ach an toradh bhon rianadair cuimhne a tha crochte san adhar - duilgheadas, ach chan eil e riatanach, agus mar sin tha a h-uile dad air a cho-chur, ach chan eil e ag obair.
Is dòcha gun obraicheadh a h-uile càil leis an t-seann mhodal nan deidheadh an rianadair ùrachadh, ach airson a-nis tha mi ro leisg dèiligeadh ri biastagan fleòdraidh a dh’ fhaodadh a bhith ann: tha gu leòr agam fhìn.
Mar sin, an dèidh gluasad timebase-frequency ann an DTS bhon ìre CPU sònraichte gu ìre an nód cpus (a rèir iarrtas a tha gu math so-thuigsinn bhon kernel), gheibh sinn:

Ceart gu leòr, lorg e rudeigin, is dòcha gu bheil sin gu leòr. Càite an deach an consol? Bheir an rannsachadh ceangal don chùis air Github: - tha e a 'tionndadh a-mach gu bheil UART a-mhàin, a rèir an dràibhear, chan eil fiù' s fhiach bruidhinn mu dheidhinn. Ach le deit 11 Iuchar, 2018 - bliadhna air ais. Thionndaidh e a-mach nach do rinn an gealladh seo a-steach don chraoibh às a bheil mi a 'togail an uillt.
