CONFIG_PREEMPT_NONE=y: Remove preemptiveness for servers. Under heads, we are single tasking. No point having this big thing in kernel https://lwn.net/Articles/746780/ IO scheduler: only enable CONFIG_MQ_IOSCHED_DEADLINE=y since we want maximum throughput and do not have concurrent tasks CONFIG_CPU_ISOLATION=y : Enable CPU Isolation accross all boards: this permits to make sure that the kernel tasks running on a CPU are not distrurbed bu user tasks CONFIG_MULTIUSER not defined: Removing cluttering since we are single root user under Heads anyway CONFIG_IO_URING=y : limit number of copy operations between kernel and user space from apps CONFIG_ZONE_DMA not defined: relevant for older hardware (less then 32bit addressing space) CONFIG_X86_MPPARSE not defined: relevant for older smp systems CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is enabled and SCHEDUTIL is disabled: we want performance with CPU sched with deadline IO. CONFIG_PERF_EVENTS_INTEL_UNCORE and CONFIG_PERF_EVENTS_INTEL_CSTATE not defined: we want max perf on Heads CONFIG_X86_VSYSCALL_EMULATION not defined: no need for syscall emulation under Heads CONFIG_SECCOMP not defined : usefull if BPF is enabled and used. CONFIG_ACPI_SPCR_TABLE=y : usefull for serial redirection table and earlycon CONFIG_PCI_MMCONFIG CONFIG_MMCONF_FAM10H unset but for kgpe-d16 which is either fam10h of fam15h CONFIG_DM_SNAPSHOT=y CONFIG_DM_THIN_PROVISIONING=y so that recovery shell can provide LVM/DM functionality in later PR. CONFIG_EXFAT_FS=y so that exfat preformated thumb drives can work out of the box Adjust CONFIG_HW_RANDOM per platform, removing CONFIG_HW_RANDOM_TIMERIOMEM Only support processor family needed per board (AMD only AMD, Intel only Intel, removing CONFIG_CPU_SUP_HYGON CONFIG_CPU_SUP_HYGON CONFIG_CPU_SUP_CENTAUR CONFIG_CPU_SUP_ZHAOXIN CONFIG_CPU_SUP_ZHAOXIN everywhere qemu: support both AMD and INTEL as an exception for the above. Removed unused compiled modules unpacked under modules.cpio Removed not needed crypto modules compiled in or as modules, reviewed from https://github.com/osresearch/heads/issues/1396#issuecomment-1538780319 : CONFIG_CRYPTO=y CONFIG_CRYPTO_ALGAPI=y CONFIG_CRYPTO_ALGAPI2=y CONFIG_CRYPTO_AEAD=y CONFIG_CRYPTO_AEAD2=y CONFIG_CRYPTO_SKCIPHER=y CONFIG_CRYPTO_SKCIPHER2=y CONFIG_CRYPTO_HASH=y CONFIG_CRYPTO_HASH2=y CONFIG_CRYPTO_RNG=y CONFIG_CRYPTO_RNG2=y CONFIG_CRYPTO_AKCIPHER2=y CONFIG_CRYPTO_KPP2=y CONFIG_CRYPTO_ACOMP2=y CONFIG_CRYPTO_MANAGER=y CONFIG_CRYPTO_MANAGER2=y CONFIG_CRYPTO_USER=y CONFIG_CRYPTO_MANAGER_DISABLE_TESTS=y CONFIG_CRYPTO_NULL=y CONFIG_CRYPTO_NULL2=y CONFIG_CRYPTO_CRYPTD=y CONFIG_CRYPTO_AUTHENC=y CONFIG_CRYPTO_SIMD=y CONFIG_CRYPTO_GLUE_HELPER_X86=y CONFIG_CRYPTO_CBC=y CONFIG_CRYPTO_ECB=y CONFIG_CRYPTO_XTS=y CONFIG_CRYPTO_ESSIV=y CONFIG_CRYPTO_HMAC=y CONFIG_CRYPTO_CRC32C=y CONFIG_CRYPTO_CRC32C_INTEL=y CONFIG_CRYPTO_MD5=y CONFIG_CRYPTO_SHA1=y CONFIG_CRYPTO_SHA1_SSSE3=y CONFIG_CRYPTO_SHA256_SSSE3=y CONFIG_CRYPTO_SHA512_SSSE3=y CONFIG_CRYPTO_SHA256=y CONFIG_CRYPTO_SHA512=y CONFIG_CRYPTO_AES_NI_INTEL=y CONFIG_CRYPTO_USER_API=y CONFIG_CRYPTO_USER_API_HASH=y CONFIG_CRYPTO_USER_API_SKCIPHER=y CONFIG_CRYPTO_USER_API_RNG=y CONFIG_CRYPTO_USER_API_AEAD=y CONFIG_CRYPTO_HASH_INFO=y CONFIG_CRYPTO_LIB_AES=y CONFIG_CRYPTO_LIB_SHA256=y |
