This is a patch to load 64-bit modules to CKSEG0 so that can be compiled with -msym32 option. This makes each module ~10% smaller. * introduce MODULE_START and MODULE_END * custom module_alloc() * PGD for modules * change XTLB refill handler synthesizer * enable -msym32 for modules again (revert ca78b1a5c6a6e70e052d3ea253828e49b5d07c8a) New XTLB refill handler looks like this: 80000080 dmfc0 k0,C0_BADVADDR 80000084 bltz k0,800000e4 # goto l_module_alloc 80000088 lui k1,0x8046 # %high(pgd_current) 8000008c ld k1,24600(k1) # %low(pgd_current) 80000090 dsrl k0,k0,0x1b # l_vmalloc_done: 80000094 andi k0,k0,0x1ff8 80000098 daddu k1,k1,k0 8000009c dmfc0 k0,C0_BADVADDR 800000a0 ld k1,0(k1) 800000a4 dsrl k0,k0,0x12 800000a8 andi k0,k0,0xff8 800000ac daddu k1,k1,k0 800000b0 dmfc0 k0,C0_XCONTEXT 800000b4 ld k1,0(k1) 800000b8 andi k0,k0,0xff0 800000bc daddu k1,k1,k0 800000c0 ld k0,0(k1) 800000c4 ld k1,8(k1) 800000c8 dsrl k0,k0,0x6 800000cc mtc0 k0,C0_ENTRYLO0 800000d0 dsrl k1,k1,0x6 800000d4 mtc0 k1,C0_ENTRYL01 800000d8 nop 800000dc tlbwr 800000e0 eret 800000e4 dsll k1,k0,0x2 # l_module_alloc: 800000e8 bgez k1,80000008 # goto l_vmalloc 800000ec lui k1,0xc000 800000f0 dsubu k0,k0,k1 800000f4 lui k1,0x8046 # %high(module_pg_dir) 800000f8 beq zero,zero,80000000 800000fc nop 80000000 beq zero,zero,80000090 # goto l_vmalloc_done 80000004 daddiu k1,k1,0x4000 80000008 dsll32 k1,k1,0x0 # l_vmalloc: 8000000c dsubu k0,k0,k1 80000010 beq zero,zero,80000090 # goto l_vmalloc_done 80000014 lui k1,0x8046 # %high(swapper_pg_dir) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> |
