From: Joshua Kinard <kumba@xxxxxxxxxx> Inspired by Maciej's recent patch to update DEC cpu-feature-overrides.h, I updated IP27's as well to disable features known to not apply to the IP27 platform or the R10K-series of CPUs. Before: text data bss dec hex filename 8616648 463200 472240 9552088 91c0d8 vmlinux After: text data bss dec hex filename 8592256 471392 472240 9535888 918190 vmlinux I believe the increase in the size of the data section is for the same reasons as in the DEC patch.

I'll also send one for IP32 shortly, as that needs some more careful updating due to the various CPUs it supports. linux-mips-ip27-update-cpu-feature-overrides.patch diff --git a/arch/mips/include/asm/mach-ip27/cpu-feature-overrides.h b/arch/mips/include/asm/mach-ip27/cpu-feature-overrides.h index d6111aa..7449794 100644 --- a/arch/mips/include/asm/mach-ip27/cpu-feature-overrides.h +++ b/arch/mips/include/asm/mach-ip27/cpu-feature-overrides.h @@ -11,47 +11,69 @@ #include <asm/cpu.h> /* - * IP27 only comes with R10000 family processors all using the same config + * IP27 only comes with R1x000 family processors, all using the same config */ -#define cpu_has_watch 1 -#define cpu_has_mips16 0 -#define cpu_has_divec 0 -#define cpu_has_vce 0 -#define cpu_has_cache_cdex_p 0 -#define cpu_has_cache_cdex_s 0 -#define cpu_has_prefetch 1 -#define cpu_has_mcheck 0 -#define cpu_has_ejtag 0 +#define cpu_has_tlb 1 +#define cpu_has_tlbinv 0 +#define cpu_has_segments 0 +#define cpu_has_eva 0 +#define cpu_has_htw 0 +#define cpu_has_rixiex 0 +#define cpu_has_maar 0 +#define cpu_has_rw_llb 0 +#define cpu_has_3kex 0 +#define cpu_has_4kex 1 +#define cpu_has_3k_cache 0 +#define cpu_has_4k_cache 1 +#define cpu_has_6k_cache 0 +#define cpu_has_8k_cache 0 +#define cpu_has_tx39_cache 0 +#define cpu_has_fpu 1 +#define cpu_has_nofpuex 0 +#define cpu_has_32fpr 1 +#define cpu_has_counter 1 +#define cpu_has_watch 1 +#define cpu_has_64bits 1 +#define cpu_has_divec 0 +#define cpu_has_vce 0 +#define cpu_has_cache_cdex_p 0 +#define cpu_has_cache_cdex_s 0 +#define cpu_has_prefetch 1 +#define cpu_has_mcheck 0 +#define cpu_has_ejtag 0 +#define cpu_has_llsc 1 +#define cpu_has_mips16 0 +#define cpu_has_mdmx 0 +#define cpu_has_mips3d 0 +#define cpu_has_smartmips 0 +#define cpu_has_rixi 0 +#define cpu_has_xpa 0 +#define cpu_has_vtag_icache 0 +#define cpu_has_dc_aliases 0 +#define cpu_has_ic_fills_f_dc 0 -#define cpu_has_llsc 1 -#define cpu_has_vtag_icache 0 -#define cpu_has_dc_aliases 0 -#define cpu_has_ic_fills_f_dc 0 -#define cpu_has_dsp 0 -#define cpu_has_dsp2 0 #define cpu_icache_snoops_remote_store 1 -#define cpu_has_mipsmt 0 -#define cpu_has_userlocal 0 -#define cpu_has_nofpuex 0 -#define cpu_has_64bits 1 - -#define cpu_has_4kex 1 -#define cpu_has_3k_cache 0 -#define cpu_has_6k_cache 0 -#define cpu_has_4k_cache 1 -#define cpu_has_8k_cache 0 -#define cpu_has_tx39_cache 0 +#define cpu_has_mips32r1 0 +#define cpu_has_mips32r2 0 +#define cpu_has_mips64r1 0 +#define cpu_has_mips64r2 0 +#define cpu_has_mips32r6 0 +#define cpu_has_mips64r6 0 +#define cpu_has_dsp 0 +#define cpu_has_dsp2 0 +#define cpu_has_mipsmt 0 +#define cpu_has_userlocal 0 #define cpu_has_inclusive_pcaches 1 +#define cpu_hwrena_impl_bits 0 +#define cpu_has_perf_cntr_intr_bit 0 +#define cpu_has_vz 0 +#define cpu_has_fre 0 +#define cpu_has_cdmm 0 -#define cpu_dcache_line_size() 32 -#define cpu_icache_line_size() 64 -#define cpu_scache_line_size() 128 - -#define cpu_has_mips32r1 0 -#define cpu_has_mips32r2 0 -#define cpu_has_mips64r1 0 -#define cpu_has_mips64r2 0 +#define cpu_dcache_line_size() 32 +#define cpu_icache_line_size() 64 +#define cpu_scache_line_size() 128 #endif /* __ASM_MACH_IP27_CPU_FEATURE_OVERRIDES_H */
