* mt7601u: use EWMA to calculate avg_rssiStanislaw Gruszka2018-04-243-6/+13
| | | | | | | | | | | | | avr_rssi is not calculated correctly as we do not divide result by 256 (mt76 sum avg_rssi1 and avg_rssi2 and divide by 512). However dividing by 256 will make avg_rssi almost the same as last rssi value - not really an average. So use EWMA to calculate avg_rssi. I've chosen weight_rcp=4 to convergence quicker on signal strength changes.

| * mt7601u: use firmware_request_cache() to address cache on rebootLuis R. Rodriguez2018-03-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | request_firmware_cache() will ensure the firmware is available on resume from suspend if on reboot the device retains the firmware. This optimization is in place given otherwise on reboot we have to reload the firmware, the opmization saves us about max 1s, minimum 10ms. Cantabile has reported back this fixes his woes with both suspend and hibernation.

The main changes are: 1) Add raw BPF tracepoint API in order to have a BPF program type that can access kernel internal arguments of the tracepoints in their raw form similar to kprobes based BPF programs. This infrastructure also adds a new BPF_RAW_TRACEPOINT_OPEN command to BPF syscall which returns an anon-inode backed fd for the tracepoint object that allows for automatic detach of the BPF program resp. unregistering of the tracepoint probe on fd release, from Alexei. 2) Add new BPF cgroup hooks at bind() and connect() entry in order to allow BPF programs to reject, inspect or modify user space passed struct sockaddr, and as well a hook at post bind time once the port has been allocated. They are used in FB's container management engine for implementing policy, replacing fragile LD_PRELOAD wrapper intercepting bind() and connect() calls that only works in limited scenarios like glibc based apps but not for other runtimes in containerized applications, from Andrey. 3) BPF_F_INGRESS flag support has been added to sockmap programs for their redirect helper call bringing it in line with cls_bpf based programs. Support is added for both variants of sockmap programs, meaning for tx ULP hooks as well as recv skb hooks, from John. 4) Various improvements on BPF side for the nfp driver, besides others this work adds BPF map update and delete helper call support from the datapath, JITing of 32 and 64 bit XADD instructions as well as offload support of bpf_get_prandom_u32() call. Initial implementation of nfp packet cache has been tackled that optimizes memory access (see merge commit for further details), from Jakub and Jiong. 5) Removal of struct bpf_verifier_env argument from the print_bpf_insn() API has been done in order to prepare to use print_bpf_insn() soon out of perf tool directly. This makes the print_bpf_insn() API more generic and pushes the env into private data. bpftool is adjusted as well with the print_bpf_insn() argument removal, from Jiri. 6) Couple of cleanups and prep work for the upcoming BTF (BPF Type Format). The latter will reuse the current BPF verifier log as well, thus bpf_verifier_log() is further generalized, from Martin. 7) For bpf_getsockopt() and bpf_setsockopt() helpers, IPv4 IP_TOS read and write support has been added in similar fashion to existing IPv6 IPV6_TCLASS socket option we already have, from Nikita. 8) Fixes in recent sockmap scatterlist API usage, which did not use sg_init_table() for initialization thus triggering a BUG_ON() in scatterlist API when CONFIG_DEBUG_SG was enabled. This adds and uses a small helper sg_init_marker() to properly handle the affected cases, from Prashant. 9) Let the BPF core follow IDR code convention and therefore use the idr_preload() and idr_preload_end() helpers, which would also help idr_alloc_cyclic() under GFP_ATOMIC to better succeed under memory pressure, from Shaohua. 10) Last but not least, a spelling fix in an error message for the BPF cookie UID helper under BPF sample code, from Colin. ==================== Signed-off-by: David S.

This patch does not fix a reported issue but makes the usb access more robust to concurrent operations on the same register since it is theoretically possible that read and write accesses of mt7601u_rmw/mt7601u_rmc can be interleaved with a different write operation on the same register. Moreover using __mt7601u_rr and __mt7601u_vendor_single_wr in mt7601u_rmw/mt7601u_rmc allows to grab vendor_req_mutex mutex once instead of twice Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@redhat.com> Acked-by: Jakub Kicinski <kubakici@wp.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not.

|/ | | | | | | | | | | | | | | As we're running out of hardware capability flags pretty quickly, convert them to use the regular test_bit() style unsigned long bitmaps. This introduces a number of helper functions/macros to set and to test the bits, along with new debugfs code. The occurrences of an explicit __clear_bit() are intentional, the drivers were never supposed to change their supported bits on the fly. We should investigate changing this to be a per-frame flag.

* add mt7601u driverJakub Kicinski2015-05-2826-0/+7930
Add support for the simplest of MediaTek Wi-Fi devices - MT7601U. It is a single stream bgn chip with no bells or whistles. This driver is partially based on Felix's mt76 but IMHO it doesn't make sense to merge the two right now because MT7601U is a design somewhere between old Ralink devices and new Mediatek chips. There wouldn't be all that much code sharing with the devices mt76 supports. Situation may obviously change when someone decides to extend m76 with support for the more recent USB dongles. The driver supports only station mode. I'm hoping to add AP support when time allows. This driver sat on GitHub for quite a while and got some testing there: http://github.com/kuba-moo/mt7601u Signed-off-by: Jakub Kicinski <kubakici@wp.pl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
