* MFC r298890:kib2016-05-081-1/+0
| | | | | | Make it explicit that D_MEM cdevsw d_flag is to signify that the driver is (or behaves identically to) /dev/mem. Remove the D_MEM flag from random drivers.

| | | | | | | | dev_ref() in the clone handlers that still use it. - Don't set SI_CHEAPCLONE flag, it's not used anywhere neither in devfs (for anything real) Reviewed by: kib
* Update d_mmap() to accept vm_ooffset_t and vm_memattr_t.rnoland2009-12-291-2/+3
| | | | | | | | | | | | | This replaces d_mmap() with the d_mmap2() implementation and also changes the type of offset to vm_ooffset_t. Purge d_mmap2(). All driver modules will need to be rebuilt since D_VERSION is also bumped. Reviewed by: jhb@ MFC after: Not in this lifetime...

* Replace all calls to minor() with dev2unit().ed2008-09-271-1/+1
| | | | | | | | | | | | | | | After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere. This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware. Reviewed by: kib

| | | | | | | | | | | | | event handler, dev_clone, which accepts a credential argument. Implementors of the event can ignore it if they're not interested, and most do. This avoids having multiple event handler types and fall-back/precedence logic in devfs. This changes the kernel API for /dev cloning, and may affect third party packages containg cloning kernel modules. Requested by: phk MFC after: 3 days

* MFp4(simokawa_firewire):simokawa2003-04-171-294/+83
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Spotted by: Yoshihiro Tabira <tabira@scd.mei.co.jp> - Improve self id handling Tested on: i386, sparc64 and i386 with forced bounce buffer

* MFp4(simokawa_sbp branch)simokawa2003-02-271-0/+8
| | | | | | | | | | | | | | | | | | | 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.
* Cleanup of the d_mmap_t interface.mux2003-02-251-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | - 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.
