Partie 4: Toujours en cours d'exécution Linux sur RISC-V RISC-V

Dans l'image, le noyau Linux vous envoie des salutations via GPIO.


Dans cette partie de l'histoire, lors du portage du RISC-V RocketChip sur une carte chinoise avec Cyclone IV, nous continuerons d'exécuter Linux et apprendrons également à configurer nous-mêmes le contrôleur de mémoire IP Core et à modifier légèrement la description dts du matériel. Cet article est une continuation de la troisième partie , mais, contrairement à la précédente assez grande, il sera assez court.


... Puisque setup_smp n'est appelé que si le noyau est configuré avec le support SMP, vous pouvez essayer de désactiver le multicœur. Ce sera désagréable si j'ai également besoin d'implémenter la prise en charge de l'atomicité dans le module de mémoire (il m'a semblé que le cache est en train de bricoler tout seul), mais dans le cas d'un cœur unique, cela ne devrait pas nous arrêter.


Elle n'a tout de même pas décollé ...

Fait intéressant, après tout le débogage, j'ai décidé de voir à quoi devrait ressembler la sortie du noyau "référence", a déclaré make qemu , et j'ai vu une erreur similaire.


Hélas, le niveau suivant (noyau Linux) est plus compliqué: GDB, connecté via JTAG à RocketChip, fonctionne apparemment avec des adresses physiques quelle que soit la configuration de la MMU, et le noyau a déjà configuré le mappage d'adresses au moment qui nous intéresse, alors disons simplement display/10i $pc échoue - nous ne verrons que beaucoup de unimp . Mais, si nous avons déjà compris le biais (il semble que 0x80200000 -> 0xffffffe000000000 ), alors nous pouvons tricher:


 1: x/10i $pc => 0xffffffe000002436 <setup_smp>: unimp 0xffffffe000002438 <setup_smp+2>: unimp 0xffffffe00000243a <setup_smp+4>: unimp 0xffffffe00000243c <setup_smp+6>: unimp 0xffffffe00000243e <setup_smp+8>: unimp 0xffffffe000002440 <setup_smp+10>: unimp 0xffffffe000002442 <setup_smp+12>: unimp 0xffffffe000002444 <setup_smp+14>: unimp 0xffffffe000002446 <setup_smp+16>: unimp 0xffffffe000002448 <setup_smp+18>: unimp (gdb) undisplay 1 (gdb) display/10i ($pc - 0xffffffe000002436 + 0x80202436) 2: x/10i ($pc - 0xffffffe000002436 + 0x80202436) 0x80202436: addi sp,sp,-96 0x80202438: sd s0,80(sp) 0x8020243a: sd s1,72(sp) 0x8020243c: sd s2,64(sp) 0x8020243e: sd s3,56(sp) 0x80202440: sd s4,48(sp) 0x80202442: sd s5,40(sp) 0x80202444: sd s6,32(sp) 0x80202446: sd s7,24(sp) 0x80202448: sd s8,16(sp)

Des points d'arrêt sont apposés de la même manière:


 (gdb) p setup_smp $1 = {<text variable, no debug info>} 0xffffffe000002436 <setup_smp> (gdb) b *0x80202436 Breakpoint 1 at 0x80202436 (gdb) c Continuing. Program received signal SIGTRAP, Trace/breakpoint trap. setup_smp () at /home/trosinenko/freedom-u-sdk/linux/arch/riscv/kernel/smpboot.c:58 58 while ((dn = of_find_node_by_type(dn, "cpu"))) { (gdb) bt #0 setup_smp () at /home/trosinenko/freedom-u-sdk/linux/arch/riscv/kernel/smpboot.c:58 #1 0xffffffe0000022a2 in setup_arch () at /home/trosinenko/freedom-u-sdk/linux/arch/riscv/kernel/setup.c:253 #2 0x0000000000000000 in ?? () Backtrace stopped: frame did not save the PC

C'est juste que vous devez les supprimer manuellement pour aller plus loin - pour GDB, c'est un piège complètement incompréhensible. Oh oui, si vous dites accidentellement s ou n au lieu de si , gdb essaiera d'insérer un point d'arrêt implicite, qui pour des raisons évidentes ne sera pas défini, mais il n'y a aucun moyen de dissuader GDB. Mais ne vous précipitez pas pour redémarrer la carte - selon mes observations, il suffit de redémarrer uniquement gdb (notez que les anciens points d'arrêt ne peuvent pas disparaître).


En fait, vous devez faire face au problème initial: le placement du débogage of_find_node_by_type dans la fonction of_find_node_by_type utilisée par le code de recherche du noyau du processeur de démarrage montre qu'il voit une sorte d'ordure au lieu des noms de type de périphérique. Par exemple, il prend la ligne «Port série» quelque part, bien que ce ne soit évidemment pas en dtb dans le champ device_type . Après avoir recherché ces octets dans l'image du noyau, je les ai trouvés, j'ai regardé le décalage et j'ai réalisé l'évidence: la taille du noyau dans les paramètres de démarrage est clairement sous-estimée: il lui est alloué 8 Mo et il en faut plus de dix. Alloué 16 Mo, mais les bizarreries ne se sont pas arrêtées. Après avoir dansé en lisant FDT à partir d'adresses différentes (normalement l'adresse est transmise au noyau dans le registre a1 ), j'ai finalement décidé de tracer, mais ce qui y est analysé maintenant. Heureusement, au lieu d'aller avec un débogueur (et nous nous souvenons qu'il y a des nuances avec la traduction d'adresse qui doivent encore être résolues d'une manière ou d'une autre), vous pouvez simplement spécifier #define pr_debug printk dans le #define pr_debug printk drivers/of/fdt.c Le résultat est:
