* Extend the rman(9) API to support altering an existing resource.John Baldwin2011-04-292-0/+161
| | | | | | | | | | | | | | | | | | | | | Specifically, these changes allow a resource to back a relocatable and resizable resource such as the I/O window decoders in PCI-PCI bridges. - rman_adjust_resource() can adjust the start and end address of an existing resource. It only succeeds if the newly requested address space is already free. It also supports shrinking a resource in which case the freed space will be marked unallocated in the rman. - rman_first_free_region() and rman_last_free_region() return the start and end addresses for the first or last unallocated region in an rman, respectively. This can be used to determine by how much the resource backing an rman must be adjusted to accomodate an allocation request that does not fit into the existing rman. While here, document the rm_start and rm_end fields in struct rman, rman_is_region_manager(), the bound argument to rman_reserve_resource_bound(), and rman_init_from_resource().

* Detect VMware guest and set the TSC frequency as reported by the hypervisor.Jung-uk Kim2011-04-291-17/+101
| | | | | | | | | | VMware products virtualize TSC and it run at fixed frequency in so-called "apparent time". Although virtualized i8254 also runs in apparent time, TSC calibration always gives slightly off frequency because of the complicated timer emulation and lost-tick correction mechanism.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | persist state and the retransmit timer. However, the code that implements "bad retransmit recovery" only checks t_rxtshift to see if an ACK has been received in during the first retransmit timeout window. As a result, if ticks has wrapped over to a negative value and a socket is in the persist state, it can incorrectly treat an ACK from the remote peer as a "bad retransmit recovery" and restore saved values such as snd_ssthresh and snd_cwnd. However, if the socket has never had a retransmit timeout, then these saved values will be zero, so snd_ssthresh and snd_cwnd will be set to 0. If the socket is in fast recovery (this can be caused by excessive duplicate ACKs such as those fixed by 220794), then each ACK that arrives triggers either NewReno or SACK partial ACK handling which clamps snd_cwnd to be no larger than snd_ssthresh. In effect, the socket's send window is permamently stuck at 0 even though the remote peer is advertising a much larger window and pending data is only sent via TCP window probes (so one byte every few seconds). Fix this by adding a new TCP pcb flag (TF_PREVVALID) that indicates that the various snd_*_prev fields in the pcb are valid and only perform "bad retransmit recovery" if this flag is set in the pcb. The flag is set on the first retransmit timeout that occurs and is cleared on subsequent retransmit timeouts or when entering the persist state.

* Introduce AR9130 (HOWL) WMAC support to the FreeBSD HAL.Adrian Chadd2011-04-2819-93/+1376
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AR9130 is an AR9160/AR5416 family WMAC which is glued directly to the AR913x SoC peripheral bus (APB) rather than via a PCI/PCIe bridge. The specifics: * A new build option is required to use the AR9130 - AH_SUPPORT_AR9130. This is needed due to the different location the RTC registers live with this chip; hopefully this will be undone in the future. This does currently mean that enabling this option will break non-AR9130 builds, so don't enable it unless you're specifically building an image for the AR913x SoC. * Add the new probe, attach, EEPROM and PLL methods specific to Howl. * Add a work-around to ah_eeprom_v14.c which disables some of the checks for endian-ness and magic in the EEPROM image if an eepromdata block is provided. This'll be fixed at a later stage by porting the ath9k probe code and making sure it doesn't break in other setups (which my previous attempt at this did.) * Sprinkle Howl modifications throughput the interrupt path - it doesn't implement the SYNC interrupt registers, so ignore those. * Sprinkle Howl chip powerup/down throughout the reset path; the RTC methods were * Sprinkle some other Howl workarounds in the reset path. * Hard-code an alternative setup for the AR_CFG register for Howl, that sets up things suitable for Big-Endian MIPS (which is the only platform this chip is glued to.) This has been tested on the AR913x based TP-Link WR-1043nd mode, in legacy, HT/20 and HT/40 modes. Caveats: * 2ghz has only been tested. I've not seen any 5ghz radios glued to this chipset so I can't test it. * AR5416_INTERRUPT_MITIGATION is not supported on the AR9130. At least, it isn't implemented in ath9k.
