ddfc9c4c - newbus: Move from bus_child_{pnpinfo,location}_src to bus_child_{pnpinfo,location} with sbuf

Wed, 23 Jun 2021 02:27:57 +0000

newbus: Move from bus_child_{pnpinfo,location}_src to bus_child_{pnpinfo,location} with sbufNow that the upper layers all go through a layer to tie into theseinformation functions that translates an sbuf into char * and len. Thecurrent interface suffers issues of what to do in cases of truncation,etc. Instead, migrate all these functions to using struct sbuf and theseissues go away. The caller is also in charge of any memory allocationand/or expansion that's needed during this process.Create a bus_generic_child_{pnpinfo,location} and make it default. Itjust returns success. This is for those busses that have no informationfor these items. Migrate the now-empty routines to using this asappropriate.Document these new interfaces with man pages, and oversight from before.Reviewed by: jhb, bcrSponsored by: NetflixDifferential Revision: https://reviews.freebsd.org/D29937 List of files: /freebsd-14.2/sys/powerpc/powernv/opal_dev.c

Thu, 10 Sep 2020 01:49:53 +0000

[PowerPC] Fix setting of time in OPALThere were multiple bugs in the OPAL RTC code which had never beendiscovered, as the default configuration of OPAL machines is tohave the BMC / FSP control the RTC.* Fix calling convention for setting the time -- the variables are passeddirectly in CPU registers, not via memory.* Fix bug in the bcd encoding routines.

e2e050c8 - Extract eventfilter declarations to sys/_eventfilter.h

Mon, 20 May 2019 00:38:23 +0000

Extract eventfilter declarations to sys/_eventfilter.hThis allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces headerpollution substantially.EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .cfiles into appropriate headers (e.g., sys/proc.h, powernv/opal.h).As a side effect of reduced header pollution, many .c files and headers nolonger contain needed definitions. The remainder of the patch addressesadding appropriate includes to fix those files.LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required bysys/mutex.h since r326106 (but silently protected by header pollution priorto this change).No functional change (intended). Of course, any out of tree modules thatrelied on header pollution for sys/eventhandler.h, sys/lock.h, orsys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

911a9260 - powerpc/powernv: Add OPAL heartbeat thread

Tue, 02 Apr 2019 04:00:01 +0000

powerpc/powernv: Add OPAL heartbeat threadSummary:OPAL needs to be kicked periodically in order for the firmware to makeprogress on its tasks. To do so, create a heartbeat thread to perform this taskevery N milliseconds, defined by the device tree. This task is also a centrallocation to handle all messages received from OPAL.Reviewed By: luporlDifferential Revision: https://reviews.freebsd.org/D19743 List of files: /freebsd-14.2/sys/powerpc/powernv/opal_dev.c

dac618a6 - powerpc/powernv: Add asynchronous token management for powernv

Fri, 01 Mar 2019 02:49:47 +0000

powerpc/powernv: Add asynchronous token management for powernvThe OPAL firmware only supports a finite number of in-flight asynchronousoperations. Rather than have each subsystem try to manage its own, use acentral management service to hand out tokens.More work can be done to improve asynchronous behavior, such as funnelingthings through a future OPAL heartbeat handler, but capabilities will beadded as needed.Augment the existing consumers (i2c and sensors) to use this new API.MFC after: 4 weeks List of files: /freebsd-14.2/sys/powerpc/powernv/opal_dev.c

78f4e2fe - powerpc64/powernv: re-read RTC after polling

Wed, 08 Aug 2018 21:19:07 +0000

powerpc64/powernv: re-read RTC after pollingIf OPAL_RTC_READ is busy and does not return the information on the first run,as returning OPAL_BUSY_EVENT, the system will crash since ymd and hmsm variablewill contain junk values.This is happening because we were not calling OPAL_RTC_READ again afterOPAL_POLL_EVENTS' return, which would finally replace the old/junk hmsm and ymdvalues.The code was also mixing OPAL_RTC_READ and OPAL_POLL_EVENTS return values.This patch fix this logic and guarantee that we call OPAL_RTC_READ afterOPAL_POLL_EVENTS return, and guarantee the code will only proceed ifOPAL_RTC_READ returns OPAL_SUCCESS.Reviewed by: jhibbitsApproved by: jhibbits (mentor)Differential Revision: https://reviews.freebsd.org/D16617 List of files: /freebsd-14.2/sys/powerpc/powernv/opal_dev.c
