Does that help at all? Yes, bisection results are usually very helpful, thanks. I think the problem is that previously psrs was always 1 and PSR_HYPV always set, so maximally permissive MMU_HYPV_INDEX was always selected by cpu_mmu_index (bug!). Also because PSR_HYPV is no longer set, some checks in translate.c indicate privilege violations. The logic was previously such that if the CPU does not have a hypervisor mode, for compatibility, supervisor mode would also select hypervisor mode (or at least that was my intention and probably Igor wasn't aware of this, sorry). Now that they are separate, CPUs without hypervisor mode must be handled differently. Perhaps this commit should be reverted, the fix won't be so trivial. The lesson here is also that subtle assumptions like this should be documented. ^ permalink raw reply [flat|nested] 6+ messages in thread

Yeah, I do too. I originally thought that the Debian kernel was broken, but if you leave it long enough then it does proceed to the end. My guess is that there is a bug in the OpenBIOS console which is obscuring the output. The first part of the boot below happens reasonably quickly; then like you the console puts out lots of junk before it returns: OpenBIOS for Sparc64 Configuration device id QEMU version 1 machine id 0 kernel cmdline CPUs: 1 x SUNW,UltraSPARC-IIi UUID: 00000000-0000-0000-0000-000000000000 Welcome to OpenBIOS v1.0 built on May 28 2010 08:24 Type 'help' for detailed information [sparc64] Booting file 'cdrom' with parameters '' Not a bootable ELF image Not a Linux kernel image Loading a.out image...

Not quite sure why some of the entries are duplicated though.

Related code in helper_ld_asi() states: case 0x24: // Nucleus quad LDD 128 bit atomic case 0x2c: // Nucleus quad LDD 128 bit atomic LE // Only ldda allowed raise_exception(TT_ILL_INSN); return 0; HelenOS also uses quad ldd when configured with TSB for memory management. I guess that atomic quad ldd deserves to be implemented. I'll see if it is not hard. -- Kind regards, Igor V. Kovalenko ^ permalink raw reply [flat|nested] 6+ messages in thread
