Log: Add initial Raspberry Pi 3 support RPI3 kernel config builds kernel compatible with latest upstream device tree and firmware: https://github.com/raspberrypi/firmware/tree/master/boot As of today it's 597c662a613df1144a6bc43e5f4505d83bd748ca Default console is PL01x, so pi3-disable-bt dt overlay should be configured in config.txt and stock U-Boot should be patched to use proper serial port. Yet unsupported: SMP, VCHIQ, RNG driver. RNG requires some work due to upstream device tree incompatibility. Multiple people contributed to this work over time: db@, loos@, manu@ Added: head/sys/arm64/broadcom/ head/sys/arm64/broadcom/bcm2837/ head/sys/arm64/broadcom/bcm2837/files.bcm2837 (contents, props changed) head/sys/arm64/conf/RPI3 (contents, props changed) Modified: head/sys/arm/broadcom/bcm2835/bcm2835_vcbus.h head/sys/conf/options.arm64 Modified: head/sys/arm/broadcom/bcm2835/bcm2835_vcbus.h ============================================================================== --- head/sys/arm/broadcom/bcm2835/bcm2835_vcbus.h Fri Oct 14 03:32:20 2016 (r307256) +++ head/sys/arm/broadcom/bcm2835/bcm2835_vcbus.h Fri Oct 14 03:37:35 2016 (r307257) @@ -37,7 +37,7 @@ #define BCM2835_VCBUS_IO_BASE 0x7E000000 #define BCM2835_VCBUS_SDRAM_UNCACHED 0xC0000000 -#ifdef SOC_BCM2836 +#if defined(SOC_BCM2836) || defined(SOC_BCM2837) #define BCM2835_ARM_IO_BASE 0x3f000000 #define BCM2835_VCBUS_SDRAM_BASE BCM2835_VCBUS_SDRAM_UNCACHED #else Added: head/sys/arm64/broadcom/bcm2837/files.bcm2837 ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/sys/arm64/broadcom/bcm2837/files.bcm2837 Fri Oct 14 03:37:35 2016 (r307257) @@ -0,0 +1,4 @@ +# $FreeBSD$ + +arm/broadcom/bcm2835/bcm2836.c standard +kern/kern_clocksource.c standard Added: head/sys/arm64/conf/RPI3 ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ head/sys/arm64/conf/RPI3 Fri Oct 14 03:37:35 2016 (r307257) @@ -0,0 +1,160 @@ +# +# +# RPI3 -- Custom configuration for the Raspberry Pi 3 +# +# For more information on this file, please read the config(5) manual page, +# and/or the handbook section on Kernel Configuration Files: +# +# http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html +# +# The handbook is also available locally in /usr/share/doc/handbook +# if you've installed the doc distribution, otherwise always see the +# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the +# latest information. +# +# An exhaustive list of options and more detailed explanations of the +# device lines is also present in the ../../conf/NOTES and NOTES files. +# If you are in doubt as to the purpose or necessity of a line, check first +# in NOTES. +# +# $FreeBSD$ + +cpu ARM64 +ident RPI3 + +files "../../arm/broadcom/bcm2835/files.bcm283x" +files "../broadcom/bcm2837/files.bcm2837" + +makeoptions DEBUG=-g # Build kernel with gdb(1) debug symbols +#makeoptions WITH_CTF=1 # Run ctfconvert(1) for DTrace support + +options SCHED_ULE # ULE scheduler +options PREEMPTION # Enable kernel thread preemption +options INET # InterNETworking +options INET6 # IPv6 communications protocols +options IPSEC # IP (v4/v6) security +options TCP_HHOOK # hhook(9) framework for TCP +options TCP_OFFLOAD # TCP offload +options SCTP # Stream Control Transmission Protocol +options FFS # Berkeley Fast Filesystem +options SOFTUPDATES # Enable FFS soft updates support +options UFS_ACL # Support for access control lists +options UFS_DIRHASH # Improve performance on big directories +options UFS_GJOURNAL # Enable gjournal-based UFS journaling +options QUOTA # Enable disk quotas for UFS +options MD_ROOT # MD is a potential root device +options NFSCL # Network Filesystem Client +options NFSD # Network Filesystem Server +options NFSLOCKD # Network Lock Manager +options NFS_ROOT # NFS usable as /, requires NFSCL +options MSDOSFS # MSDOS Filesystem +options CD9660 # ISO 9660 Filesystem +options PROCFS # Process filesystem (requires PSEUDOFS) +options PSEUDOFS # Pseudo-filesystem framework +options GEOM_PART_GPT # GUID Partition Tables. +options GEOM_RAID # Soft RAID functionality. +options GEOM_LABEL # Provides labelization +options SCSI_DELAY=5000 # Delay (in ms) before probing SCSI +options KTRACE # ktrace(1) support +options STACK # stack(9) support +options SYSVSHM # SYSV-style shared memory +options SYSVMSG # SYSV-style message queues +options SYSVSEM # SYSV-style semaphores +options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions +options PRINTF_BUFR_SIZE=128 # Prevent printf output being interspersed. +options KBD_INSTALL_CDEV # install a CDEV entry in /dev +options HWPMC_HOOKS # Necessary kernel hooks for hwpmc(4) +options AUDIT # Security event auditing +options CAPABILITY_MODE # Capsicum capability mode +options CAPABILITIES # Capsicum capabilities +options MAC # TrustedBSD MAC Framework +options KDTRACE_FRAME # Ensure frames are compiled in +options KDTRACE_HOOKS # Kernel DTrace hooks +options VFP # Floating-point support +options RACCT # Resource accounting framework +options RACCT_DEFAULT_TO_DISABLED # Set kern.racct.enable=0 by default +options RCTL # Resource limits +# SMP is not there yet +# options SMP +options INTRNG + +# Debugging support.
