Add asmcmmio.c/asmcmmio.h implementing the MMIO transport:key read/write, getinfo, getbyindex, and a poll-based wait withexponential backoff.The driver probes for MMIO at attach time by checking the LDKN firmwareversion key; if MMIO is available it is used, otherwise the standardI/O port backend is used.T2 fan speeds use IEEE 754 floats instead of fpe2 fixed-point.Per-fan manual mode uses F%dMd keys instead of the FS! bitmask.Battery charge limit is exposed via dev.asmc.N.battery_charge_limit.Tested on: MacBookPro16,2 (A2251, iBridge2,10) MacBookPro15,4 (A2159, iBridge2,8) MacBookAir8,2 (A1932, iBridge2,5) Mac mini 8,1 (A1993, iBridge2,7) iMac20,2 (A2115, iBridge2,16) iMacPro1,1 (A1862, iBridge1,1)MFC after: 2 weeksReviewed by: ngie, adrianDifferential Revision: https://reviews.freebsd.org/D57086 List of files: /freebsd/sys/modules/asmc/Makefile Wed, 03 Jun 2026 07:57:49 +0200 Abdelkader Boudih <freebsd@seuros.com> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#5d7862fb998f48ba71dac7e34106aaad350db348 asmc(4): Add support for backlight(9) interfaceMFC after: 1 month List of files: /freebsd/sys/modules/asmc/Makefile Sun, 29 Mar 2026 21:00:59 +0200 Vladimir Kondratyev <wulf@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#f224591746bdaf14ad5f63de4738a3146cc2f55f Add ASMC_DEBUG make optionThis allows folks to enable debug statements in asmc(4) using kernelconfigs via the `options ASMC_DEBUG` directive.While here, remove a duplicate `device vt_efifb` directive in `NOTES`as it's already handled in the `GENERIC` configMFC after: 1 weekDifferential Revision: https://reviews.freebsd.org/D54511 List of files: /freebsd/sys/modules/asmc/Makefile Sun, 04 Jan 2026 09:27:57 +0100 Enji Cooper <ngie@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#e9ac41698b2f322d55ccf9da50a3596edb2c1800 Remove residual blank line at start of MakefileThis is a residual of the $FreeBSD$ removal.MFC After: 3 days (though I'll just run the command on the branches)Sponsored by: Netflix List of files: /freebsd/sys/modules/asmc/Makefile Mon, 15 Jul 2024 06:46:32 +0200 Warner Losh <imp@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#031beb4e239bfce798af17f5fe8dba8bcaf13d99 sys: Remove $FreeBSD$: one-line sh patternRemove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/ List of files: /freebsd/sys/modules/asmc/Makefile Wed, 16 Aug 2023 19:54:58 +0200 Warner Losh <imp@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#a0638b33f7ae4e7435e9cac57541d2cc262432f7 Yank crufty INTR_FILTER optionIt was introduced to the tree in r169320 and r169321 in May 2007.It never got much use and never became a kernel default. The codeduplicates the default path quite a bit, with slight modifications. Justyank out the cruft. Whatever goals were being aimed for can probably be metwithin the existing framework, without a flag day option.Mostly mechanical change: 'unifdef -m -UINTR_FILTER'.Reviewed by: mmacySponsored by: Dell EMC IsilonDifferential Revision: https://reviews.freebsd.org/D15546 List of files: /freebsd/sys/modules/asmc/Makefile Thu, 24 May 2018 19:06:00 +0200 Conrad Meyer <cem@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#193d9e768ba63fcfb187cfd17f461f7d41345048 sys/modules: normalize .CURDIR-relative paths to SRCTOPThis simplifies make output/logicTested with: `cd sys/modules; make ALL_MODULES=` on amd64MFC after: 1 monthSponsored by: Dell EMC Isilon List of files: /freebsd/sys/modules/asmc/Makefile Sat, 04 Mar 2017 11:10:17 +0100 Enji Cooper <ngie@FreeBSD.org> http://kernelsources.org:8080/source/history/freebsd/sys/modules/asmc/Makefile#01b18fc48a687e81b6c02d7e462220424abcae39 Remove isa_if.h.
