[ref:deadcode]) * adapt remote_event_signal to arm64 caching behaviours (vchiq_kmod.c) * refactor synchronization around remote_event_signal, forcing a wmb to be on the safe side; thereby make it look more like what linux does [ref:sync] (vchiq_{core,kmod}.c); and make a comment in vchiq_core.c true (wasn't before) * add a few more syncs to be on the safe side (vchiq_2835_arm.c) * use arm64 dcache invalidation mechanisms (vchiq_2835_arm.c) * explicitly invalidate pages on arm64 post bulk-read (vchiq_2835_arm.c) * support bulk transfers on rpi-4 (aka "long address space" transfers), by hard-coding their vc offset (0) and different bit-shift [ref:longbulk] (vchiq_2835_arm.c) * refactor a loop-of-constant-test (vchiq_2835_arm.c) * use the correct (hard-coded) cache-line size on arm64 * rework the handling of chipset "features" to account for the extra behaviours with 64 bit chipsets. (vchiq_kmod.c) * add sysctl-s (log, arm_log) to control debug (vchiq_kmod.c) * add example kernel config (GENERIC-VCHIQ)Fixes: * Rework error handling in create_pagelist, avoiding a potential panic when freeing memory that had been dmamem_alloc, a potential null dereference, and a leak when having problems pinning pages (vchiq_2835_arm.c) * fix a confusion about the behaviour cv_wait_sig that lead to uninterruptible looping (vchiq_bsd.c) * implement detection of fatal signals (vchiq_bsd.c) * fix a confusion with the name of a variable introduced by #a0b8746 that could lead to a panic when closing the cdev file (vchiq_arm.c) * release user connection when destructing cdevpriv and avoid user processes sharing connection data, which lead to stalls and data corruption. (vchiq_arm.c)Update bcm2835_audio to work on 64bit systems: * update VC audio fields (vc_vchi_audioserv_defs.h, bcm2835_audio.c) * repurpose the hitherto unused callback field to help push a 64 bit pointer in (bcm2835_audio.c) * increase (hopefully) the robustness of the code that shifts data to VC (bcm2835_audio.c) * add a sysctl to control the amount of debugging info output by bcm2835_audio.cTested on zero, zero2 and 4+ with ping, functional, bulk and control vchiq_test-s, and omxplayer [ref:dsb]: https://github.com/raspberrypi/linux/commit/35b7ebda57affcfd3616d39d5a727a4495b31123 [ref:sems]: https://github.com/raspberrypi/linux/commit/24a4262afb10907fce3cdbc3ae336fcf4cdaece5 [ref:sizes]: https://github.com/raspberrypi/linux/commit/e64568b8ea6c04e747e432c17ce2452652075216 [ref:sizes2]: https://github.com/raspberrypi/linux/commit/f9bee6dd24addfa00c2c8d50c25b73efbfbb28ba [ref:deadcode]: https://github.com/raspberrypi/linux/commit/14f4d72fb799a9b3170a45ab80d4a3ddad541960 [ref:sync]: https://github.com/raspberrypi/linux/commit/51c071265079319583e4c6e8c61e09660300d0bf [ref:longbulk]: https://github.com/raspberrypi/linux/commit/37f6f19a83722c9b866cecb5e455b2e16e5bbc6bDifferential Revision: https://reviews.freebsd.org/D37878Submitted by: Marco Devesas Campos <devesas.campos@gmail.com> List of files: /freebsd/sys/arm64/conf/std.broadcom Mon, 20 Oct 2025 04:50:19 +0200 Marco Devesas Campos <devesas.campos@gmail.com> http://kernelsources.org:8080/source/history/freebsd/sys/arm64/conf/std.broadcom#589951c76a3ff5d3b1105af03d66e676c83dbffc arm64: conf: std.broadcom: Add dwcotg and smscAdd the dwcotg and smsc usb to ethernet driver to std.broadcom.Those are used in RPI3PR: 257593 List of files: /freebsd/sys/arm64/conf/std.broadcom Thu, 05 Aug 2021 13:16:23 +0200 Emmanuel Vadot <manu@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/arm64/conf/std.broadcom#0f2c633164a6af70db8a8ecf4f70f61d241e7529 arm64: Add per SoC family kernel configThere is multiple reason for this :- This makes it easier to see which driver is needed for each SoC- This makes it easier to create a custom config for one SoC- This really reduce boot time (which some people might want)Some explaination about the files :- std.arm64 contains all standard kernel option- std.dev contains all the standard kernel devices- std.<soc> contains all drivers needed to boot on this SoC family- <SOC> includes std.arm64, std.dev and std.<soc>- GENERIC includes std.arm64, std.dev and all std.<soc>Sponsored by: Diablotin SystemsMFC After: 2 monthsReviewed by: mmel, cognet, impDifferential Revision: https://reviews.freebsd.org/D30474 List of files: /freebsd/sys/arm64/conf/std.broadcom Fri, 05 Feb 2021 21:41:06 +0100 Emmanuel Vadot <manu@FreeBSD.org>
