* Mega busdma API commit.Scott Long2003-07-011-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg. Lockfunc allows a driver to provide a function for managing its locking semantics while using busdma. At the moment, this is used for the asynchronous busdma_swi and callback mechanism. Two lockfunc implementations are provided: busdma_lock_mutex() performs standard mutex operations on the mutex that is specified from lockfuncarg. dftl_lock() is a panic implementation and is defaulted to when NULL, NULL are passed to bus_dma_tag_create(). The only time that NULL, NULL should ever be used is when the driver ensures that bus_dmamap_load() will not be deferred. Drivers that do not provide their own locking can pass busdma_lock_mutex,&Giant args in order to preserve the former behaviour. sparc64 and powerpc do not provide real busdma_swi functions, so this is largely a noop on those platforms. The busdma_swi on is64 is not properly locked yet, so warnings will be emitted on this platform when busdma callback deferrals happen. If anyone gets panics or warnings from dflt_lock() being called, please let me know right away. Reviewed by: tmm, gibbs Notes: svn path=/head/; revision=117126

* One minor bugfix:Mike Smith2000-04-201-4/+18
| | | | | | | | | | | | | | | - Free resources in all the possible attachment failure cases. One critical bugfix: - Fix a race where it was possible to get out of synch with the log messages from the controller, if the controller hung up for any period of time (eg. while resetting a SCSI bus). This would result in an endless string of console errors, bringing the machine to a halt. Notes: svn path=/head/; revision=59447

* Remove B_READ, B_WRITE and B_FREEBUF and replace them with a newPoul-Henning Kamp2000-03-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set. B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes. Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL. Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading. This change is a step in the direction towards a stackable BIO capability. A lot of this patch were machine generated (Thanks to style(9) compliance!) Vinum users: Greg has not had time to test this yet, be careful. Notes: svn path=/head/; revision=58345
* Update to the latest development version of the Mylex driver. Changes inMike Smith2000-03-181-124/+438
| | | | | | | | | | | | | | | | | | | | | this version include: - Support for version 2.x firmware (2.42 or later recommended). This means we are the only open-source driver supporting these adapters. This code has only been tested on a Digital KZPCA adapter in an Alpha system, but is believed to be correct. NOTE: EISA adapters are not yet supported. - Support the BIOS/Firmware initialisation handshake protocol. This allows the driver to bring the card up to operational state even if the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system). - A working command pasthrough interface. This allows a user-space configuration tool (under development) to issue arbitrary commands to the controller or to devices in the system. Notes: svn path=/head/; revision=58188

* Updates resulting from new documentation from Mylex and some cleaning:Mike Smith1999-12-221-60/+88
| | | | | | | | | | | | | | | | | | | | | - Don't keep private copies of some of the data fields from the ENQUIRY and ENQUIRY2 commands. Instead, standardise on the ENQUIRY2 command for initial adapter information, and keep a copy of the entire structure. Refer to it where appropriate. - Move all of the controller description functionality into a new function. Print lots more controller data if bootverbose is set. Add knowledge of the DAC960 PR, PT, PTL0 and PRL controllers, rename the 960PTL -> PTL0 and 1100P -> 1100PVX. - Correctly terminate an error message. The controller interface procedures have been reviewed against the Mylex-supplied documentation; no changes appear necessary at this time. Notes: svn path=/head/; revision=54979

* Major update to the Mylex DAC960 driver adding new hardware supportMike Smith1999-12-111-164/+227
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and fixing some major bugs. - Add support for the v5 firmware interface, used by the DAC1164P (tested) and AcceleRAID 352 (untested but should work). We now cover all of the Mylex family's protocols except for v2 (used by EISA and Alpha-compatible cards). - Fix an accounting bug which resulted in endless 'poll still busy' messages. In situations of high controller load the count of poll commands could be incremented without actually successfully launching a command. This totally removes the accounting for status poll commnads; it was its own worst enemy. - Add some simple reentry prevention locks to processing of the waiting and completed command queues to prevent races which could result in I/O being done or completed twice (both are fatal). This highlights a need for simple locking primitives in both the UP and SMP kernels. - Streamline the handling of command completion to reduce the amount of redundant work being done. Remove the code which tests for commands that have gone missing in action; nobody has ever seen one of these and it wouldn't have worked properly anyhow. - Handle disconnection of drives from the controller in the detach, not shutdown method. This avoids problems flushing the cache in a panic when a drive is mounted. - Don't call bus_generic_detach when disconnecting drives; it doesn't actually do anything useful. - Increment the log message index regardless of whether we actually retrieved one or not. If we run into a message that we can't fetch, we don't want to spin endlessly complaining about the fact. - Don't assume that interrupts will work when we're flushing the controller. We may think they are enabled, but in eg. a panic situation the controller may not be able to deliver an interrupt. Notes: svn path=/head/; revision=54419
* Remove the 'ivars' arguement to device_add_child() andMatthew N. Dodd1999-12-031-1/+2
| | | | | | | | | | | | | | | | | | | device_add_child_ordered(). 'ivars' may now be set using the device_set_ivars() function. This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc. Despite my best efforts I've probably forgotten something so let me know if this breaks anything. I've been running with this change for months and its been quite involved actually isolating all the changes from the rest of the local changes in my tree.
