* acpi: Make taskqueue only run on BSPAymeric Wibo6 days1-1/+5
| | | | | | | | | | | | | | This is needed because when we add the suspend-to-idle loop, we only want to break the BSP out of idle to process the taskqueue while keeping all the others idled. Currently assuming BSP to be CPU0, which may not always be the case on non-x86.

* pci_cfgreg: Add a PCI domain argument to the low-level register APIJohn Baldwin2023-11-291-3/+3
| | | | | | | | | | | | | | | | | | | | | | | This commit changes the API of pci_cfgreg(read|write) to add a domain argument (referred to as a segment in ACPI parlance) (note that this is not the same as a NUMA domain, but something PCI-specific). This does not yet enable access to domains other than 0, but updates the API to support domains. Places that use hard-coded bus/slot/function addresses have been updated to hardcode a domain of 0. A few places that have the PCI domain (segment) available such as the acpi_pcib_acpi.c Host-PCI bridge driver pass the PCI domain. The hpt27xx(4) and hptnr(4) drivers fail to attach to a device not on domain 0 since they provide APIs to their binary blobs that only permit bus/slot/function addressing. The x86 non-ACPI PCI bus drivers all hardcode a domain of 0 as they do not support multiple domains. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D42827

* Do not check whether AcpiOsGetTimer() is called during boot.Jung-uk Kim2017-10-101-3/+0
| | | | | | | | | | | | | From ACPICA 20170929, AcpiOsGetTimer() should be available early because While() loop timeout mechanism was reimplemented with it. Unfortunately, it means AcpiLoadTables() may cause panic when a While() loop is executed. After having lengthy discussions with ACPICA developers, I have concluded that dummy timecounter is good enough for the purpose and it is the least intrusive solution for now. Also, they reminded me the ACPI specification implies OS timer function should be available before loading tables. Notes: svn path=/head/; revision=324501
* Defer ACPI taskqueue creation to SI_SUB_KICK_SCHEDULER.Mark Johnston2017-07-051-1/+1
| | | | | | | | | | | | | | This addresses a deadlock during boot when EARLY_AP_STARTUP is configured: a taskqueue thread may call pause() with an ACPI mutex held, and thread0 may block on this mutex before configuring the eventtimer. In this case the taskqueue thread will sleep forever waiting for its callout to fire. PR: 220277 Submitted by: jhb MFC after: 3 days Notes: svn path=/head/; revision=320690

* Use polling spin loops for timeouts during early boot.John Baldwin2016-05-161-0/+34
| | | | | | | | | | | | | | | | | Some ACPI operations such as mutex acquires and event waits accept a timeout. The ACPI OSD layer implements these timeouts by using regular sleep timeouts. However, this doesn't work during early boot before event timers are setup. Instead, use polling combined with DELAY() to spin. This fixes booting on upcoming Intel systems with Kaby Lake processors.

* Extend the meaning of the CTLFLAG_TUN flag to automatically check ifHans Petter Selasky2014-06-271-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | there is an environment variable which shall initialize the SYSCTL during early boot. This works for all SYSCTL types both statically and dynamically created ones, except for the SYSCTL NODE type and SYSCTLs which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to be used in the case a tunable sysctl has a custom initialisation function allowing the sysctl to still be marked as a tunable. The kernel SYSCTL API is mostly the same, with a few exceptions for some special operations like iterating childrens of a static/extern SYSCTL node. This operation should probably be made into a factored out common macro, hence some device drivers use this. The reason for changing the SYSCTL API was the need for a SYSCTL parent OID pointer and not only the SYSCTL parent OID list pointer in order to quickly generate the sysctl path. The motivation behind this patch is to avoid parameter loading cludges inside the OFED driver subsystem. Instead of adding special code to the OFED driver subsystem to post-load tunables into dynamically created sysctls, we generalize this in the kernel. Other changes: - Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask" to "hw.pcic.intr_mask". - Removed redundant TUNABLE statements throughout the kernel. - Some minor code rewrites in connection to removing not needed TUNABLE statements. - Added a missing SYSCTL_DECL(). - Wrapped two very long lines. - Avoid malloc()/free() inside sysctl string handling, in case it is called to initialize a sysctl from a tunable, hence malloc()/free() is not ready when sysctls from the sysctl dataset are registered. - Bumped FreeBSD version to indicate SYSCTL API change.
