| H A D | vlan.4 | diff 89431 Wed Jan 16 14:33:58 MST 2002 ambrisko Add VLAN for the dc(4) driver (ie long frame). The patch is 2 parts. One to notify the system that the MTU for VLAN can be 1500 so the vlan will automatically be configured with a 1500 MTU the other is to ignore the error case if the received frame is to long. The frame size notification came from code in the SIS driver, and the support for long frames derived from the NetBSD Tulip driver. Tested on: 4 port D-Link adapter DFE-570TX 4 Intel 21143 Netgear card with 82c169 PNIC 10/100BaseTX Reviewed by: ru (manpage), wpaul (not objected to), archie Approved by: imp Obtained from: NetBSD |

| H A D | if_em.h | diff 154204 Tue Jan 10 22:30:25 MST 2006 scottl Significant performance improvements for the if_em driver: - Only update the rx ring consumer pointer after running through the rx loop, not with each iteration through the loop. - If possible, use a fast interupt handler instead of an ithread handler. Use the interrupt handler to check and squelch the interrupt, then schedule a taskqueue to do the actual work. This has three benefits: - Eliminates the 'interrupt aliasing' problem found in many chipsets by allowing the driver to mask the interrupt in the NIC instead of the OS masking the interrupt in the APIC. - Allows the driver to control the amount of work done in the interrupt handler. This results in what I call 'adaptive polling', where you get the latency benefits of a quick response to interrupts with the interrupt mitigation and work partitioning of polling. Polling is still an option in the driver, but I consider it orthogonal to this work. - Don't hold the driver lock in the RX handler. The handler and all data associated is effectively serialized already. This eliminates the cost of dropping and reaquiring the lock for every receieved packet. The result is much lower contention for the driver lock, resulting in lower CPU usage and lower latency for interactive workloads. The amount of work done in the taskqueue is controlled by the sysctl dev.em.N.rx_processing_limit and tunable hw.em.rx_process_limit Setting these to -1 effectively removes the limit. The fast interrupt and taskqueue can be disabled by defining NO_EM_FASTINTR. This work has been shown to increase fast-forwarding from ~570 kpps to ~750 kpps (note that the same NIC hardware seems unable to transmit more than 800 kpps, so this increase appears to be limited almost solely by the hardware). Gains have been shown in other workloads, ranging from better performance to elimination of over-saturation livelocks. Thanks to Andre Opperman for his time and resources from his network performance project in performing much of the testing. Thanks to Gleb Smirnoff and Danny Braniss for their help in testing also. |

| H A D | locore.s | diff 570 Sun Oct 10 04:07:57 MDT 1993 rgrimes SYSPDROFF and SYSPDREND are now calculated using KERNBASE, KERNSIZE and PDRSHIFT. The SYSTEM constant that was defined in this file has been replaced with KERNBASE from param.h. Changed almost all # style comments to /* */ C style comments. Several comments cleaned up so that they make a little more since. In the comments that describe C calling conventions to assembler routines used a comma space sequence to seperate arguments and removed the space between the function name and the argument list. Removed useless comments like /* clr eax */. Changed all comma space sequences on assemble instructions to just be comma. Removed spaces after $ operators to make the file consistent, this may need to change again (ie: $KERNBASE should probably be $(KERNBASE), but for now it all seems to work just fine.) This may become a problem with the C pre-processor. Changed several double blank lines to single blank lines that where used to seperate the I/O routines, these routines are blocked enough that we don't need double blank lines between them. Changed sequence of I/O routines to be all input functions, all output functions instead of just the opposite. Moved the SHOW_A_LOT debug stuff to near the end of the file. Changed two occurances of the constant 0xfff to NBPG-1. |
