2015-05-21sfc: Change entity reset on MC reboot to a new datapath-only reset.Jon Cooper
Currently we do an entity reset when we detect an MC reboot. This messes up SRIOV because it leaves VFs orphaned. The extra reset is rather redundant anyway, since the MC reboot will have basically reset everything. This change replaces the entity reset after MC reboot with a simpler datapath reset that reallocates resources but doesn't perform the entity reset.

2014-04-16sfc:On MCDI timeout, issue an FLR (and mark MCDI to fail-fast)Edward Cree
When an MCDI command times out (whether or not we find it completed when we poll), call efx_mcdi_abandon(), which tells all subsequent MCDI calls to fail-fast, and queues up an FLR. Because an FLR doesn't lead to receiving any reboot even from the MC (unlike most other types of reset), we have to call efx_ef10_reset_mc_allocations. In efx_start_all(), if a reset (of any kind) is pending, we bail out. Without this, attempts to reconfigure (e.g. change mtu) can cause driver/mc state inconsistency if the first MCDI call triggers an FLR. For similar reasons, on EF10, in efx_reset_down(method=RESET_TYPE_MCDI_TIMEOUT), set the number of active queues to zero before calling efx_stop_all(). And, on farch, in efx_reset_up(method=RESET_TYPE_MCDI_TIMEOUT), set active_queues and flushes pending & outstanding to zero. efx_mcdi_mode_{poll,event}() should not take us out of fail-fast mode. Instead, this is done by efx_mcdi_reset() after the FLR completes. The new FLR reset_type RESET_TYPE_MCDI_TIMEOUT doesn't really fit into the hierarchy of reset 'scopes' whereby efx_reset() decides some resets subsume others. Thus, it uses separate logic. Also, fixed up some inconsistency around RESET_TYPE_MC_BIST, which was in the wrong place in that hierarchy. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S.

2013-12-12sfc: Add MC BISTs to ethtool offline self test on EF10Jon Cooper
To run BISTs the MC goes down in to a special mode where it will only respond to MCDI from the testing PF, and TX, RX and event queues are torn down. Other PFs get a message as it goes down to tell them it's going down. When the other PFs get this message, they check the soft status register to tell when the MC has rebooted after BIST mode and they can start recovery. [bwh: Convert the test result to 1 or -1 as for earlier NICs] Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2013-08-27sfc: Add EF10 support for TX/RX DMA error events handling.Alexandre Rames
Also, since we handle all DMA errors in the same way, merge RESET_TYPE_(RX|TX)_DESC_FETCH into RESET_TYPE_DMA_ERROR. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
2013-03-07sfc: Add AER and EEH support for SienaAlexandre Rames
The Linux side of EEH is triggered by MMIO reads, but this driver's data path does not issue any MMIO reads (except in legacy interrupt mode). Therefore add a monitor function to poll EEH periodically. When preparing to reset the device based on our own error detection, also poll EEH and defer to its recovery mechanism if appropriate. [bwh: Use a separate condition for the initial link poll; fix some style errors] Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
