Unlike as with cas(4) this only serves to speed up the the device attach though and can only be determined via the OFW device tree but not from the VPD. - Don't touch the MIF when using a SERDES. - Add some missing bus space barriers, mainly in the PCS code path. 2009-06-23T20:36:59Z Marius Strobl marius@FreeBSD.org 2009-06-23T20:36:59Z urn:sha1:9ba2b298dfda78b6669281507b314a4c441cd706 the PHYs as some PHY drivers use it (but probably shouldn't). How gem(4) has worked with brgphy(4) on powerpc without this so far is unclear to me. - Introduce a dying flag which is set during detach and checked in gem_ioctl() in order to prevent active BPF listeners to clear promiscuous mode which may lead to the tick callout being restarted which will trigger a panic once it's actually gone. - In gem_stop() reset rather than just disable the transmitter and receiver in order to ensure we're not unloading DMA maps still in use by the hardware. [1] - The blanking time is specified in PCI clocks so we should use twice the value when operating at 66MHz. - Spell some 2 as ETHER_ALIGN and a 19 as GEM_STATUS_TX_COMPLETION_SHFT to make the actual intentions clear. - As we don't unload the peak attempts counter ignore its overflow interrupts. - Remove a stale setting of a variable to GEM_TD_INTERRUPT_ME which isn't used afterwards. - For optimum performance increment the TX kick register in multiples of 4 if possible as suggested by the documentation. - Partially revert r164931; drivers should only clear the watchdog timer if all outstanding TX descriptors are done. - Fix some debugging strings. - Add a missing BUS_DMASYNC_POSTWRITE in gem_rint(). - As the error paths in the interrupt handler are generally unlikely predict them as false. - Add support for the SBus version of the GEM controller. [2] - Add some lock assertions. - Improve some comments. - Fix some more or less cosmetic issues in the code of the PCI front-end. - Change some softc members to be unsigned where more appropriate and remove unused ones.
