I've found bug in my implementation and fixed it. Today evening I'll test if my patch fixes performance anyhow (I need physical access). Larry: I've found two mistakes/lacks in the specs. 1) http://bcm-v4.sipsolutions.net/802.11/PmuSpurAvoid This routine ignores my BCM43224. However from wl MMIO dump I can see it should make some ops on my chip. Example log from wl: write32 0xfaaff660 <- 0x00000000 write32 0xfaaff664 <- 0x11100010 write32 0xfaaff660 <- 0x00000001 write32 0xfaaff664 <- 0x000c0c06 write32 0xfaaff660 <- 0x00000002 write32 0xfaaff664 <- 0x03000a08 write32 0xfaaff660 <- 0x00000003 write32 0xfaaff664 <- 0x00000000 write32 0xfaaff660 <- 0x00000004 write32 0xfaaff664 <- 0x200005c0 write32 0xfaaff660 <- 0x00000005 write32 0xfaaff664 <- 0x88888815 read32 0xfaaff600 -> 0x00000381 write32 0xfaaff600 <- 0x00000781 2) http://bcm-v4.sipsolutions.net/802.11/PHY/N/ChanspecSetup There is condition: "If the chip is greater than 0x4349 and less then 0x4356". This should but applied "too"/"instead" for BCM43224 at least. wl executes that commands for my BCM43224: write16 0xfaafc62e <- 0x8889 write16 0xfaafc630 <- 0x0008 -- Rafał _______________________________________________ b43-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/b43-dev
