2015-04-15fm10k: reset head instead of calling update_max_sizeJeff Kirsher1-2/+16
When we forcefully shutdown the mailbox, we then go about resetting max size to 0, and clearing all messages in the FIFO. Instead, we should just reset the head pointer so that the FIFO becomes empty, rather than changing the max size to 0. This helps prevent increment in tx_dropped counter during mailbox negotiation, which is confusing to viewers of Linux ethtool statistics output.

The use of dropped doesn't really mean dropped mailbox messages, but rather specifically messages which were too large to fit in the remote Rx FIFO.

2015-04-15fm10k: update xcast mode before synchronizing multicast addressesJeff Kirsher1-11/+11
When the PF receives a request to update a multicast address for the VF, it checks the enabled multicast mode first. Fix a bug where the VF tried to set a multicast address before requesting the required xcast mode. This ensures the multicast addresses are honored as long as the xcast mode was allowed.

Add a header comment explaining why we have the somewhat crazy mailbox flow. This flow is necessary as it prevents the PF<->SM mailbox from being flooded by the VF messages, which normally trigger a message to the PF.

2015-04-15fm10k: don't handle mailbox events in iov_event path and always process mailboxJeff Kirsher2-32/+5
Since we already schedule the service task, we can just wait for this task to handle the mailbox events from the VF. This reduces some complex code flow, and makes it so we have a single path for handling the VF messages. There is a possibility that we have a slight delay in handling VF messages, but it should be minimal. The result of tx_complete and !rx_ready is insufficient to determine whether we need to process the mailbox. There is a possible race condition whereby the VF fills up the mbmem for us, but we have already recently processed the mailboxes in the interrupt. During this time, the interrupt is disabled. Thus, our Rx FIFO is empty, but the mbmem now has data in it. Since we continually check whether Rx FIFO is empty, we then never call process. This results in the possibility to prevent PF from handling the VF mailbox messages. Instead, just call process every time, despite the fact that we may or may not have anything to process for the VF. There should be minimal overhead for doing this, and it resolves an issue where the VF never comes up due to never getting response for its SET_LPORT_STATE message.

2015-04-15fm10k: use separate workqueue for fm10k driverJeff Kirsher3-1/+16
Since we run the watchdog periodically, which might take a while and potentially monopolize the system default workqueue, create our own separate work queue. This also helps reduce and stabilize latency between scheduling the work in our interrupt and actually performing the work. Still use a timer for the regular scheduled interval but queue the work onto its own work queue. It seemed overkill to create a single workqueue per interface, so we just spawn a single work queue for all interfaces upon driver load. For this reason, use a multi-threaded workqueue with one thread per processor, rather than single threaded queue.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "Some clean ups and small fixes, but the biggest change is the addition of the TRACE_DEFINE_ENUM() macro that can be used by tracepoints. Tracepoints have helper functions for the TP_printk() called __print_symbolic() and __print_flags() that lets a numeric number be displayed as a a human comprehensible text. What is placed in the TP_printk() is also shown in the tracepoint format file such that user space tools like perf and trace-cmd can parse the binary data and express the values too. Unfortunately, the way the TRACE_EVENT() macro works, anything placed in the TP_printk() will be shown pretty much exactly as is. The problem arises when enums are used. That's because unlike macros, enums will not be changed into their values by the C pre-processor. Thus, the enum string is exported to the format file, and this makes it useless for user space tools. The TRACE_DEFINE_ENUM() solves this by converting the enum strings in the TP_printk() format into their number, and that is what is shown to user space. For example, the tracepoint tlb_flush currently has this in its format file: __print_symbolic(REC->reason, { TLB_FLUSH_ON_TASK_SWITCH, "flush on task switch" }, { TLB_REMOTE_SHOOTDOWN, "remote shootdown" }, { TLB_LOCAL_SHOOTDOWN, "local shootdown" }, { TLB_LOCAL_MM_SHOOTDOWN, "local mm shootdown" }) After adding: TRACE_DEFINE_ENUM(TLB_FLUSH_ON_TASK_SWITCH); TRACE_DEFINE_ENUM(TLB_REMOTE_SHOOTDOWN); TRACE_DEFINE_ENUM(TLB_LOCAL_SHOOTDOWN); TRACE_DEFINE_ENUM(TLB_LOCAL_MM_SHOOTDOWN); Its format file will contain this: __print_symbolic(REC->reason, { 0, "flush on task switch" }, { 1, "remote shootdown" }, { 2, "local shootdown" }, { 3, "local mm shootdown" })" * tag 'trace-v4.1' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: (27 commits) tracing: Add enum_map file to show enums that have been mapped writeback: Export enums used by tracepoint to user space v4l: Export enums used by tracepoints to user space SUNRPC: Export enums in tracepoints to user space mm: tracing: Export enums in tracepoints to user space irq/tracing: Export enums in tracepoints to user space f2fs: Export the enums in the tracepoints to userspace net/9p/tracing: Export enums in tracepoints to userspace x86/tlb/trace: Export enums in used by tlb_flush tracepoint tracing/samples: Update the trace-event-sample.h with TRACE_DEFINE_ENUM() tracing: Allow for modules to convert their enums to values tracing: Add TRACE_DEFINE_ENUM() macro to map enums to their values tracing: Update trace-event-sample with TRACE_SYSTEM_VAR documentation tracing: Give system name a pointer brcmsmac: Move each system tracepoints to their own header iwlwifi: Move each system tracepoints to their own header mac80211: Move message tracepoints to their own header tracing: Add TRACE_SYSTEM_VAR to xhci-hcd tracing: Add TRACE_SYSTEM_VAR to kvm-s390 tracing: Add TRACE_SYSTEM_VAR to intel-sst ...

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid Pull HID updates from Jiri Kosina: - quite a few firmware fixes for RMI driver by Andrew Duggan - huion and uclogic drivers have been substantially overlaping in functionality laterly. This redundancy is fixed by hid-huion driver being merged into hid-uclogic; work done by Benjamin Tissoires and Nikolai Kondrashov - i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg - Some of the quirks, that got separated into individual drivers, have historically had EXPERT dependency. As HID subsystem matured (as well as the individual drivers), this made less and less sense. This dependency is now being removed by patch from Jean Delvare - Logitech lg4ff driver received a couple of improvements for mode switching, by Michal Malý - multitouch driver now supports clickpads, patches by Benjamin Tissoires and Seth Forshee - hid-sensor framework received a substantial update; namely support for Custom and Generic pages is being added; work done by Srinivas Pandruvada - wacom driver received substantial update; it now supports i2c-conntected devices (Mika Westerberg), Bamboo PADs are now properly supported (Benjamin Tissoires), much improved battery reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng) - small assorted fixes and device ID additions * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (68 commits) HID: sensor: Update document for custom sensor HID: sensor: Custom and Generic sensor support HID: debug: fix error handling in hid_debug_events_read() Input - mt: Fix input_mt_get_slot_by_key HID: logitech-hidpp: fix error return code HID: wacom: Add support for Cintiq 13HD Touch HID: logitech-hidpp: add a module parameter to keep firmware gestures HID: usbhid: yet another mouse with ALWAYS_POLL HID: usbhid: more mice with ALWAYS_POLL HID: wacom: set stylus_in_proximity before checking touch_down HID: wacom: use wacom_wac_finger_count_touches to set touch_down HID: wacom: remove hardcoded WACOM_QUIRK_MULTI_INPUT HID: pidff: effect can't be NULL HID: add quirk for PIXART OEM mouse used by HP HID: add HP OEM mouse to quirk ALWAYS_POLL HID: wacom: ask for a in-prox report when it was missed HID: hid-sensor-hub: Fix sparse warning HID: hid-sensor-hub: fix attribute read for logical usage id HID: plantronics: fix Kconfig default HID: pidff: support more than one concurrent effect ...
2015-04-14ACPI / battery: Fix doubly added battery on system suspendKrzysztof Kozlowski1-1/+1
Commit 297d716f6260 ("power_supply: Change ownership from driver to core") inverted the logic in battery_notify(). As an effect already present battery was re-added on each system suspend or hibernation.
