* Change and clean the mutex lock interface.bmilekic2001-02-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* Fix support for cardbus cards:wpaul2000-10-301-1/+3
| | | | | | | | | | - Add DRIVER_MODULE() declaration to make this driver a child of cardbus - Handle different width EEPROMs The CIS parser still barfs when scanning this card, but it seems to probe/attach correctly anyway. I can't do a traffic test just yet since I don't have a proper crossover cable handy.
* Add PCI IDs for some additional cardbus cards. Yes, there really iswpaul2000-10-281-0/+1
| | | | | | | a RealTek 8139 cardbus device. Unfortunately it doesn't quite work yet because the CIS parser barfs on it. Submitted by msmith, with some small tweaks by me.

| | | | | | | | takes care of all the 10/100 and gigE PCI drivers that I've done. Next will be the wireless drivers, then the USB ones. I may pick up some stragglers along the way. I'm sort of playing this by ear: if anyone spots any places where I've screwed up horribly, please let me know.
* Make some tweaks to the RealTek driver:wpaul1999-10-211-1/+3
| | | | | | | | | | | | | | | | | | - Fix a bug in rl_rxeof() handler: in the case where the packet wraps from the end of the receive buffer back to the beginning, we need to insure that at least sizeof(ether_header) bytes make it into the first mbuf. If we don't, then doing eh = mtod(m, struct ether_header *) loses. To avoid this, we use m_pullup() to suck at least MHLEN - RL_ETHER_ALIGN bytes into the first mbuf, which should also help small packets fit into a single mbuf. Pointed out by: Philip A. Prindeville <philipp@zembu.com> - Make the transmit threshold autotuning: start off with a small value and jack it up when TX underruns are detected. - Also improve TX error recovery: kick the chip in the head with a reset/init sequence to make sure it recovers afer a transmit error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | few changes: - there was a bug in rl_list_tx_init(): it was calculating the registers to initialize incorrectly. Not a problem on the x86 where unaligned access are allowed, but a problem on the alpha. - set rl_btag accordingly depending on the machine type - rl_rxeof() needs to be sure to longword-align the packet data. This is a little tricky since we copy the data out of the receive buffer using m_devget(), however there's no way to tell m_devget() to fill in the mbufs starting at a particular offset. To get around this, we tell m_devget to copy bytes+2 bytes starting at offset offset-2. This results in the proper alignment, and we can trim off the two leading bytes afterwards with m_adj(). We also allocate some extra space before the start of the receive buffer so that we don't get into trouble in the case where offset == 0. - redefine vtophys() in if_rlreg.h for the alpha. Making this chipset work on the alpha is sort of the inverse of putting a jet engine on a rowboat (putting a propeller on a 747?) but when you can get these things for $5 a pop, it's hard to stop people from buying them.

* Merge in some updates for the RealTek driver, mainly:wpaul1999-04-121-27/+53
| | | | | | - Rewrite the transmit section to be a little less bogus. - Set ifq_maxlen correctly. RL_TX_LIST_CNT - 1 is wrong, because for the RealTek, RL_TX_LIST_CNT is 4. Set it to IFQ_MAXLEN instead.
* Add support for still more cheapo 10/100 cards: Delta Electronics andwpaul1999-02-231-6/+26
| | | | | | | | | | Addtron appear to have their own VIA Rhine II and RealTek 8139 boards with custom PCI vendor and device IDs. This commit updates the PCI vendor and device lists in the vr and rl drivers so that we can probe the additional devices. Found by: nosing around the PCI vendor and device code list at: http://www.halcyon.com/scripts/jboemler/pci/pcicode

* The Accton 1207D adapter uses a chip called the MXP 5030 (or 5038)wpaul1998-11-181-3/+11
| | | | | | | | | | | | | | which is either a RealTek 8139 in disguise or a RealTek workalike. This commit fixes the PCI vendor/device ID for this device and updates the description string to reflect the actual identity of the device. I also changed the transmit encapsulation routine to always to buffer copies on transmit. We end up doing this 99% of the time anyway. I also tweaked the code that pads packets out to the minimum length (60) bytes. I was fixing up the m_pkthdr.len value but not m_len. I don't think this makes that much difference in the grand scheme of things, but it makes me feel better.
* Add driver support for PCI fast ethernet adapters based on thewpaul1998-10-181-0/+564
RealTek 8129/8139 chipset like I've been threatening. Update kernel configs, userconfig.c, relnotes and sysinstall. No man page yet; comming soon. I consider this driver stable enough that I want to give it some exposure in -current.
