* - Change ichsmb(4) to follow the format of all the other smbus controllersjhb2009-02-031-10/+10
| | | | | | | | | | | | | for slave addressing by using left-adjusted slave addresses (i.e. xxxxxxx0b). - Require the low bit of the slave address to always be zero in smb(4) to help catch broken applications. - Adjust some code in the IPMI driver to not convert the slave address for SSIF to a right-adjusted address. I (or possibly ambrisko@) added this in the past to (unknowingly) work around the bug in ichsmb(4). Submitted by: Andriy Gapon <avg of icyb.net.ua> (1,2) MFC after: 1 month

* Various updates to most of the smbus(4) drivers:jhb2007-01-112-45/+35
| | | | | | | | | | | | | | | | | | - Use printf() and device_printf() instead of log() in ichsmb(4). - Create the mutex sooner during ichsmb(4) attach. - Attach the interrupt handler later during ichsmb(4) attach to avoid races. - Don't try to set PCIM_CMD_PORTEN in ichsmb(4) attach as the PCI bus driver does this already. - Add locking to alpm(4), amdpm(4), amdsmb(4), intsmb(4), nfsmb(4), and viapm(4). - Axe ALPM_SMBIO_BASE_ADDR, it's not really safe to write arbitrary values into BARs, and the PCI bus layer will allocate resources now if needed. - Merge intpm(4) and intsmb(4) into just intsmb(4). Previously, intpm(4) attached to the PCI device and created an intsmb(4) child. Now, intsmb(4) just attaches to PCI directly. - Change several intsmb functions to take a softc instead of a device_t to make things simpler.
* Minor overhaul of SMBus support:jhb2006-09-111-12/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Change smbus_callback() to pass a void * rather than caddr_t. - Change smbus_bread() to pass a pointer to the count and have it be an in/out parameter. The input is the size of the buffer (same as before), but on return it will contain the actual amount of data read back from the bus. Note that this value may be larger than the input value. It is up to the caller to treat this as an error if desired. - Change the SMB_BREAD ioctl to write out the updated struct smbcmd which will contain the actual number of bytes read in the 'count' field. To preserve the previous ABI, the old ioctl value is mapped to SMB_OLD_BREAD which doesn't copy the updated smbcmd back out to userland. I doubt anyone actually used the old BREAD anyway as it was rediculous to do a bulk-read but not tell the using program how much data was actually read. - Make the smbus driver and devclass public in the smbus module and push all the DRIVER_MODULE()'s for attaching the smbus driver to various foosmb drivers out into the foosmb modules. This makes all the foosmb logic centralized and allows new foosmb modules to be self-contained w/o having to hack smbus.c everytime a new smbus driver is added. - Add a new SMB_EINVAL error bit and use it in place of EINVAL to return an error for bad arguments (such as invalid counts for bread and bwrite). - Map SMB bus error bits to EIO in smbus_error(). - Make the smbus driver call bus_generic_probe() and require child drivers such as smb(4) to create device_t's via identify routines. Previously, smbus just created one anonymous device during attach, and if you had multiple drivers that could attach it was just random chance as to which driver got to probe for the sole device_t first. - Add a mutex to the smbus(4) softc and use it in place of dummy splhigh() to protect the 'owner' field and perform necessary synchronization for smbus_request_bus() and smbus_release_bus(). - Change the bread() and bwrite() methods of alpm(4), amdpm(4), and viapm(4) to only perform a single transaction and not try to use a loop of multiple transactions for a large request. The framing and commands to use for a large transaction depend on the upper-layer protocol (such as SSIF for IPMI over SMBus) from what I can tell, and the smb(4) driver never allowed bulk read/writes of more than 32-bytes anyway. The other smb drivers only performed single transactions. - Fix buffer overflows in the bread() methods of ichsmb(4), alpm(4), amdpm(4), amdsmb(4), intpm(4), and nfsmb(4). - Use SMB_xxx errors in viapm(4). - Destroy ichsmb(4)'s mutex after bus_generic_detach() to avoid problems from child devices making smb upcalls that would use the mutex during their detach methods.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mtx_enter(lock, type) becomes: mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks) mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized) similarily, for releasing a lock, we now have: mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN. We change the caller interface for the two different types of locks because the semantics are entirely different for each case, and this makes it explicitly clear and, at the same time, it rids us of the extra `type' argument. The enter->lock and exit->unlock change has been made with the idea that we're "locking data" and not "entering locked code" in mind. Further, remove all additional "flags" previously passed to the lock acquire/release routines with the exception of two: MTX_QUIET and MTX_NOSWITCH The functionality of these flags is preserved and they can be passed to the lock/unlock routines by calling the corresponding wrappers: mtx_{lock, unlock}_flags(lock, flag(s)) and mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN locks, respectively. Re-inline some lock acq/rel code; in the sleep lock case, we only inline the _obtain_lock()s in order to ensure that the inlined code fits into a cache line. In the spin lock case, we inline recursion and actually only perform a function call if we need to spin. This change has been made with the idea that we generally tend to avoid spin locks and that also the spin locks that we do have and are heavily used (i.e. sched_lock) do recurse, and therefore in an effort to reduce function call overhead for some architectures (such as alpha), we inline recursion for this case. Create a new malloc type for the witness code and retire from using the M_DEV type. The new type is called M_WITNESS and is only declared if WITNESS is enabled. Begin cleaning up some machdep/mutex.h code - specifically updated the "optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently need those. Finally, caught up to the interface changes in all sys code. Contributors: jake, jhb, jasone (in no particular order)
