* Explicitly hold a reference to the cdev we have just cloned. Thisphk2005-03-311-0/+1
| | | | | closes the race where the cdev was reclaimed before it ever made it back to devfs lookup.

* Second half of the dev_t cleanup.phk2004-06-171-1/+1
| | | | | | | | | | | The big lines are: NODEV -> NULL NOUDEV -> NODEV udev_t -> dev_t udev2dev() -> findcdev() Various minor adjustments including handling of userland access to kernel space struct cdev etc.

Submitted by: Stefan Farfeleder <stefan@fafoe.narf.at> - Compatibility for RELENG_4 and DragonFly. * firewire - Timestamp just before queuing. - Retry bus probe if it fails. - Use device_printf() for debug message. - Invalidiate CROM while update. - Don't process minimum/invalid CROM. * sbp - Add ORB_SHORTAGE flag. - Add sbp.tags tunable. - Revive doorbell support. It's not enabled by default.
* Fix a bug introduced in rev 1.33(mega API change).simokawa2004-03-241-1/+1
| | | | | | | Because xfer->send.payload is a pointer to the buffer, '&' shouldn't be there. Submitted by: John Weisgerber <weisgerberj@gsilumonics.com> PR: misc/64623
* Device megapatch 4/6:phk2004-02-211-3/+3
| | | | | | | | Introduce d_version field in struct cdevsw, this must always be initialized to D_VERSION. Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.
* Device megapatch 1/6:phk2004-02-211-2/+0
| | | | | | | Free approx 86 major numbers with a mostly automatically generated patch. A number of strategic drivers have been left behind by caution, and a few because they still (ab)use their major number.
* Add missing free() in exception handlers.simokawa2004-01-221-2/+2
| | | | Reported by: Stanford Metacompilation research group
* Respect a return code of fwmem_open().simokawa2003-11-071-3/+3
|
* Fix for FW_ASYREQ.simokawa2003-10-241-39/+36
| | | | | | - set send.pay_len correctly. - copy response only if needed. - remove unnecessary 'err = 0'.
* MFp4: Change struct fw_xfer to reduce memory copy in fwmem_*() functions.simokawa2003-10-021-21/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | And many changes. * all - Major change of struct fw_xfer. o {send,recv}.buf is splitted into hdr and payload. o Remove unnecessary fields. o spd is moved under send and recv. - Remove unnecessary 'volatile' keyword. - Add definition of rtcode and extcode. * firewire.c - Ignore FWDEVINVAL devices in fw_noderesolve_nodeid(). - Check the existance of the bind before call STAILQ_REMOVE(). - Fix bug in the fw_bindadd(). - Change element of struct fw_bind for simplicity. - Check rtcode of response packet. - Reduce split transaction timeout to 200 msec. (100msec is the default value in the spec.) - Set watchdog timer cycle to 10 Hz. - Set xfer->tv just before calling fw_get_tlabel(). * fwohci.c - Simplifies fwohci_get_plen(). * sbp.c - Fix byte order of multibyte scsi_status informations. - Split sbp.c and sbp.h. - Unit number is not necessary for FIFO¤ address. - Reduce LOGIN_DELAY and SCAN_DELAY to 1 sec. - Add some constants defineded in SBP-2 spec. * fwmem.c - Introduce fwmem_strategy() and reduce memory copy.
* Fix a bug in fwdev_clone().simokawa2003-10-011-1/+1
| | | | Spotted by: grog
* Change device name notation.simokawa2003-08-051-8/+95
| | | | | | - /dev/fw{,mem}X.Y represents the Y'th unit on the X'th bus. - /dev/fw{,mem}X is an alias of fw{,mem}X.0 for compatibility. - Clone devices.
* Clean up fwdev.simokawa2003-08-011-208/+224
| | | | | Allocate iso DMA channel dynamically. This allows us to have more /dev/fw* than number of DMA channels for asyn. transactions and etc.

* 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)simokawa2003-03-061-6/+7
| | | | | | | | | | Improve if_fwe performance. - Simplify mbuf handling by using bulkxfer. Now, it uses mbuf clusters for RX buffer as usual ethernet drivers. - Recycle struct xfer buffer and don't call malloc at runtime. - Count input and output errors. - Handle a mbuf chain longer than 6 correctly. - Increase queue length.
* Gigacommit to improve device-driver source compatibility betweenphk2003-03-031-13/+10
| | | | | | | | | | | | | branches: Initialize struct cdevsw using C99 sparse initializtion and remove all initializations to default values. This patch is automatically generated and has been tested by compiling LINT with all the fields in struct cdevsw in reverse order on alpha, sparc64 and i386. Approved by: re(scottl)

* 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. Discussed with: alc, phk, jake Reviewed by: peter Compile-tested on: LINT (i386), GENERIC (alpha and sparc64) Runtime-tested on: i386

| | | | | | | | | - Fix overwrite problem of freed buffers. It was rare but could happen when fwohci_arcv() is called before fwohci_txd() is called for the transcation. - Drain AT queues and pend AR queues on SID receive rather than BUS reset to make sure DMA actually stops. - Do agent reset in sbp_timeout().
