Rakesh Pillai d9f1b99f4c UPSTREAM: ath10k: Add interrupt summary based CE processing ... [ Upstream commit b92aba35d39d10d8a6bdf2495172fd490c598b4a ] Currently the NAPI processing loops through all the copy engines and processes a particular copy engine is the copy completion is set for that copy engine. The host driver is not supposed to access any copy engine register after clearing the interrupt status register. This might result in kernel crash like the one below [ 1159.220143] Call trace: [ 1159.220170] ath10k_snoc_read32+0x20/0x40 [ath10k_snoc] [ 1159.220193] ath10k_ce_per_engine_service_any+0x78/0x130 [ath10k_core] [ 1159.220203] ath10k_snoc_napi_poll+0x38/0x8c [ath10k_snoc] [ 1159.220270] net_rx_action+0x100/0x3b0 [ 1159.220312] __do_softirq+0x164/0x30c [ 1159.220345] run_ksoftirqd+0x2c/0x64 [ 1159.220380] smpboot_thread_fn+0x1b0/0x288 [ 1159.220405] kthread+0x11c/0x12c [ 1159.220423] ret_from_fork+0x10/0x18 To avoid such a scenario, we generate an interrupt summary by reading the copy completion for all the copy engine before actually processing any of them. This will avoid reading the interrupt status register for any CE after the interrupt status is cleared.
