* Do not report MAC, TX, and RX stats via sysctl(8) with BCM5705+.Jung-uk Kim2007-11-161-7/+6
| | | | | | | | | | | | The register layout is little different from memory-mapped stats in the previous generation chips. In fact, it is bad because registers in this range are cleared after reading them. Reviewed by: scottl MFC after: 3 days Notes: svn path=/head/; revision=173675
* Make the PCI code aware of PCI domains (aka PCI segments) so we canMarius Strobl2007-09-301-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | support machines having multiple independently numbered PCI domains and don't support reenumeration without ambiguity amongst the devices as seen by the OS and represented by PCI location strings. This includes introducing a function pci_find_dbsf(9) which works like pci_find_bsf(9) but additionally takes a domain number argument and limiting pci_find_bsf(9) to only search devices in domain 0 (the only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order to no longer report false positives when searching for siblings and dupe devices in the same domain respectively. Along with this change the sole host-PCI bridge driver converted to actually make use of PCI domain support is uninorth(4), the others continue to use domain 0 only for now and need to be converted as appropriate later on. Note that this means that the format of the location strings as used by pciconf(8) has been changed and that consumers of <sys/pciio.h> potentially need to be recompiled.

| | | | | | | | | | | | | | | | sysctl_handle_int is not sizeof the int type you want to export. The type must always be an int or an unsigned int. Remove the instances where a sizeof(variable) is passed to stop people accidently cut and pasting these examples. In a few places this was sysctl_handle_int was being used on 64 bit types, which would truncate the value to be exported. In these cases use sysctl_handle_quad to export them and change the format to Q so that sysctl(1) can still print them. Notes: svn path=/head/; revision=170289

* - Add support/quirks for the on-board BGEs found in Sun Blade 1500Marius Strobl2007-04-302-34/+98
| | | | | | | | | | | | | | | | | | | | Blade 2500, Fire V210 and probably some other sparc64 machines. These chips are typically not fitted with an EEPROM which means that we have to obtain the MAC address via OFW and that some chip tests will just always fail. These changes are based on the respective code found in OpenBSD with some additional info obtained from OpenSolaris and some style suggestions by jkim@. They also have the desired side-effect of respecting the 'local-mac-address?' system configuration variable for the affected BGEs. - In bge_attach() factor out calling bge_release_resources() before going to the fail label into the fail label as well as replace a magic 6 with ETHER_ADDR_LEN.

* Avoid a race and a pessimization in bge_intr():Bruce Evans2006-12-201-6/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - moved the synchronizing bus read to after the bus write for the first interrupt ack so that it actually synchronizes everything necessary. We were acking not only the status update that triggered the interrupt together with any status updates that occurred before we got around to the bus write for the ack, but also any status updates that occur after we do the bus write but before the write reaches the device. The corresponding race for the second interrupt ack resulted in sometimes returning from the interrupt handler with acked but unserviced interrupt events. Such events then remain unserviced until further events cause another interrupt or the watchdog times out. The race was often lost on my 5705, apparently since my 5705 has broken event coalescing which causes a status update for almost every packet, so another status update is quite likely to occur while the interrupt handler is running. Watchdog timeouts weren't very noticeable, apparently because bge_txeof() has one of the usual bugs resetting the watchdog. - don't disable device interrupts while bge_intr() is running. Doing this just had the side effects of: - entering a device mode in which different coalescing parameters apply. Different coalescing parameters can be used to either inhibit or enhance the chance of getting another status update while in the interrupt handler. This feature is useless with the current organization of the interrupt handler but might be useful with a taskqueue handler. - giving a race for ack+reenable/return. This cannot be handled by simply rearranging the order of bus accesses like the race for ack+keepenable/entry. It is necessary to sync the ack and then check for new events. - taking longer, especially with the extra code to avoid the race on ack+reenable/return.

* - Correct collision counter for BCM5705+. This register is read/clear.Jung-uk Kim2006-12-111-10/+13
| | | | | | | | | | | | | | | | | | | - Correct RX packet drop counter for BCM5705+. This register is read/clear and it wraps very quickly under heavy packet drops because only the lower ten bits are valid according to the documentation. However, it seems few more bits are actually valid and the rest bits are always zeros[1]. Therefore, we don't mask them off here. To get accurate packet drop count, we need to check the register from bge_rxeof(). It is commented out for now, not to penalize normal operation. Actual performance impact should be measured later. - Correct integer casting from u_long to uint32_t. Casting is not really needed for all supported platforms but we better do this correctly[2].
