[PATCH] sparc64 implement itlb/dtlb directed writes

by Igor Kovalenko

Hi! This patch implements directed (indexed) writes to itlb/dtlb entries. Methods "SUNW,dtlb-load" and "SUNW,itlb-load" used to ignore tlb index parameter. Now the gentoo sparc64 installation iso booting traps much later :) Please apply. -- Kind regards, Igor V. Kovalenko

[PATCH] sparc64 fix virtual to physical address translation

by Igor Kovalenko

Hi! This patch fixes "translate" method implementation to actually return physical address of mapped entry. It used to return virtual base obtained from matched tte. Now it should be possible to boot gentoo install-sparc64-minimal-2008.0.iso beyond the point of "Remapping the kernel... done." Remapping the kernel... done. bootmem_init: Scan pavail, choose_bootmap_pfn: kern[400000:8b2000] avoid[c00000:da4000] choose_bootmap_pfn: Using 0 [0] init_bootmem(min[0], bootmap[0], max[3f6f]) free_bootmem(pavail:0): base[0] size[7ede000] reserve_bootmem(initrd): base[c00000] size[da3354] reserve_bootmem(kernel): base[400000] size[4b0720] reserve_bootmem(bootmap): base[0] size[7f0] memory_present(0, 0, 3f6f) -- Kind regards, Igor V.
