* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-2/+3
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
* spdx: initial adoption of licensing ID tags.Pedro F. Giffuni2017-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Initially, only tag files that use BSD 4-Clause "Original" license. RelNotes: yes Differential Revision: https://reviews.freebsd.org/D13133 Notes: svn path=/head/; revision=325966

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many internal structure changes for the FireWire driver. - Compute CRC in CROM parsing. - Add support for configuration ROM build. - Simplify dummy buffer handling. - busdma conversion - Use swi_taskqueue_giant for -current. Mark the interrupt routine as MPSAFE. - AR buffer handling. Don't reallocate AR buffer but just recycle it. Don't malloc and copy per packet in fwohci_arcv(). Pass packet to fw_rcv() using iovec. Application must prepare receiving buffer in advance. - Change fw_bind API so that application should pre-allocate xfer structure. - Add fw_xfer_unload() for recycling struct fw_xfer. - Add post_busreset hook - Remove unused 'sub' and 'act_type' in struct fw_xfer. - Remove npacket from struct fw_bulkxfer. - Don't call back handlers in fwochi_arcv() if the packet has not drained in AT queue - Make firewire works on big endian platform. - Use native endian for packet header and remove unnecessary ntohX/htonX. - Remove FWXFERQ_PACKET mode. We don't use it anymore. - Remove unnecessary restriction of FWSTMAXCHUNK. - Don't set root node for phy config packet if the root node is not cycle master capable but set myself for root node. We should be the root node after next bus reset.

* MFp4(simokawa_sbp branch)Hidetoshi Shimokawa2003-02-271-0/+4
| | | | | | | | | | | | | | | | | | | | | | Improve SBP device probeing: - Wait 2 sec before issuing LOGIN ORB expecting the reconnection hold timer expires. - Serialize management ORB and scanning LUN by CAM on each target. This should fix the problem for devices which have multiple LUNs. Test device is donated by: Jaye Mathisen <mrcpu@internetcds.com> - Freeze SIM queue for 2 sec after BUS RESET. - Retry with LOGIN rather than RECONNECT after LOGIN is not completed for BUS RESET. - Use appropriate CAM status for BUS RESET and DEVICE RESET. - Let CAM to scan targets after BUS REST. - Implement CAM scan target function. - Keep our own devq freeze count. - Let CAM to know that SBP does tagged queuing. These should be merged to RELENG_4 before 4.8-RELEASE. Notes: svn path=/head/; revision=111615
* Cleanup of the d_mmap_t interface.Maxime Henrion2003-02-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Get rid of the useless atop() / pmap_phys_address() detour. The device mmap handlers must now give back the physical address without atop()'ing it. - Don't borrow the physical address of the mapping in the returned int. Now we properly pass a vm_offset_t * and expect it to be filled by the mmap handler when the mapping was successful. The mmap handler must now return 0 when successful, any other value is considered as an error. Previously, returning -1 was the only way to fail. This change thus accidentally fixes some devices which were bogusly returning errno constants which would have been considered as addresses by the device pager. - Garbage collect the poorly named pmap_phys_address() now that it's no longer used. - Convert all the d_mmap_t consumers to the new API. I'm still not sure wheter we need a __FreeBSD_version bump for this, since and we didn't guarantee API/ABI stability until 5.1-RELEASE.
