Bagian 4: Masih menjalankan Linux di RISC-V RISC-V

Pada gambar, kernel Linux mengirimkan salam kepada Anda melalui GPIO.


Di bagian cerita ini, ketika porting RISC-V RocketChip ke motherboard Cina dengan Cyclone IV, kita masih akan menjalankan Linux, dan juga belajar bagaimana mengkonfigurasi pengontrol memori IP Core sendiri dan sedikit memodifikasi deskripsi dts dari perangkat keras. Artikel ini merupakan kelanjutan dari bagian ketiga , tetapi, tidak seperti sebelumnya yang cukup besar, itu akan cukup singkat.


... Karena setup_smp hanya dipanggil jika kernel dikonfigurasi dengan dukungan SMP, Anda dapat mencoba menonaktifkan multi-core. Ini akan menjadi tidak menyenangkan jika saya juga perlu menerapkan dukungan atomicity dalam modul memori (bagi saya sepertinya cache itu bermain-main dengan ini sendiri), tetapi dalam kasus single-core seharusnya tidak menghentikan kita.


Semua sama, itu tidak lepas landas ...

Menariknya, setelah semua debugging, saya memutuskan untuk melihat seperti apa output kernel "referensi", kata make qemu , dan melihat kesalahan yang sama.


Sayangnya, level berikutnya (kernel Linux) lebih rumit: GDB, terhubung melalui JTAG ke RocketChip, tampaknya bekerja dengan alamat fisik terlepas dari bagaimana MMU dikonfigurasi, dan kernel telah mengkonfigurasi pemetaan alamat pada saat kami tertarik, jadi katakan saja display/10i $pc gagal - kita hanya akan melihat banyak unimp . Tapi, jika kita sudah menemukan biasnya (sepertinya 0x80200000 -> 0xffffffe000000000 ), maka kita bisa menipu:


 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)

Breakpoint ditempelkan dengan cara yang sama:


 (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 ??

Hanya saja Anda harus menghapusnya secara manual untuk melangkah lebih jauh - untuk GDB ini adalah beberapa jebakan yang benar-benar tidak dapat dipahami. Oh ya, jika Anda secara tidak sengaja mengatakan s atau n alih-alih si , gdb akan mencoba menyisipkan breakpoint implisit, yang karena alasan yang jelas tidak akan ditetapkan, tetapi tidak ada cara untuk menghalangi GDB. Tapi jangan buru-buru untuk me-reboot papan - menurut pengamatan saya, cukup dengan hanya me-restart gdb (perhatikan bahwa breakpoint lama mungkin tidak hilang).


Sebenarnya, Anda harus berurusan dengan masalah awal: penempatan debugging of_find_node_by_type di fungsi of_find_node_by_type digunakan oleh kode pencarian inti prosesor boot menunjukkan bahwa ia melihat beberapa jenis sampah alih-alih nama jenis perangkat. Sebagai contoh, dibutuhkan baris "Serial port" dari suatu tempat, meskipun ini jelas tidak dalam dtb di bidang device_type . Setelah mencari byte-byte ini di kernel image, saya menemukannya, melihat offsetnya, dan menyadari yang sudah jelas: ukuran kernel pada parameter boot jelas diremehkan: dialokasikan 8Mb, dan dibutuhkan lebih dari sepuluh. Dia mengalokasikan 16MB, tetapi keanehan tidak berhenti. Setelah menari dengan membaca FDT dari alamat yang berbeda (biasanya alamat dilewatkan ke kernel di register a1 ), saya akhirnya memutuskan untuk melacak, tetapi apa yang diuraikan di sana sekarang. Untungnya, alih-alih menggunakan debugger (dan kami ingat bahwa ada nuansa dengan terjemahan alamat yang masih perlu dipecahkan dengan satu atau lain cara), Anda cukup menentukan #define pr_debug printk di file drivers/of/fdt.c Hasilnya adalah:
