I can't say that these names are my favorite. Especially _RPS_DM2. I haven't actually seen the PAPR updates that define these things, but I would hope that these had more self explanatory names. I'm not really sure what _RPS_ means. Like I said I haven't seen the PAPR update so maybe that is a new acronym defined there. -Tyrel > > #ifndef __ASSEMBLY__ > > @@ -66,7 +68,8 @@ enum { > FW_FEATURE_MULTITCE | FW_FEATURE_SPLPAR | FW_FEATURE_LPAR | > FW_FEATURE_CMO | FW_FEATURE_VPHN | FW_FEATURE_XCMO | > FW_FEATURE_SET_MODE | FW_FEATURE_BEST_ENERGY | > - FW_FEATURE_TYPE1_AFFINITY | FW_FEATURE_PRRN, > + FW_FEATURE_TYPE1_AFFINITY | FW_FEATURE_PRRN | > + FW_FEATURE_RPS_DM2 | FW_FEATURE_RPS_DRC_INFO, > FW_FEATURE_PSERIES_ALWAYS = 0, > FW_FEATURE_POWERNV_POSSIBLE = FW_FEATURE_OPAL, > FW_FEATURE_POWERNV_ALWAYS = 0, > diff --git a/arch/powerpc/include/asm/prom.h b/arch/powerpc/include/asm/prom.h > index 7f436ba..b9a1534 100644 > --- a/arch/powerpc/include/asm/prom.h > +++ b/arch/powerpc/include/asm/prom.h > @@ -155,6 +203,8 @@ struct of_drconf_cell { > #define OV5_PFO_HW_842 0x0E40 /* PFO Compression Accelerator > */ > #define OV5_PFO_HW_ENCR 0x0E20 /* PFO Encryption Accelerator */ > #define OV5_SUB_PROCESSORS 0x0F01 /* 1,2,or 4 Sub-Processors supported */ > +#define OV5_RPS_DM2 0x1680 /* Redef Prop Structures: dyn-mem-v2 */ > +#define OV5_RPS_DRC_INFO 0x1640 /* Redef Prop Structures: drc-info */ > > /* Option Vector 6: IBM PAPR hints */ > #define OV6_LINUX 0x02 /* Linux is our OS */ > diff --git a/arch/powerpc/platforms/pseries/firmware.c > b/arch/powerpc/platforms/pseries/firmware.c > index 8c80588..00243ee 100644 > --- a/arch/powerpc/platforms/pseries/firmware.c > +++ b/arch/powerpc/platforms/pseries/firmware.c > @@ -111,6 +111,8 @@ static __initdata struct vec5_fw_feature > vec5_fw_features_table[] = { > {FW_FEATURE_TYPE1_AFFINITY, OV5_TYPE1_AFFINITY}, > {FW_FEATURE_PRRN, OV5_PRRN}, > + {FW_FEATURE_RPS_DM2, OV5_RPS_DM2}, > + {FW_FEATURE_RPS_DRC_INFO, OV5_RPS_DRC_INFO}, > }; > > void __init fw_vec5_feature_init(const char *vec5, unsigned long len) > > _______________________________________________ > Linuxppc-dev mailing list > Linuxppc-dev@lists.ozlabs.org > https://lists.ozlabs.org/listinfo/linuxppc-dev > _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
