For PCIe it is logged when PCIE debug +level is enabled. For SDIO it is logged when user specifies a non-zero +console interval through debugfs. This patch tries to make it a +bit more consistent. The firmware console output is only logged when +FWCON debug level is enabled. + +Reviewed-by: Hante Meuleman <meuleman@broadcom.com> +Reviewed-by: Franky (Zhenhui) Lin <frankyl@broadcom.com> +Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> +Reviewed-by: Pontus Fuchs <pontusf@broadcom.com> +Signed-off-by: Arend van Spriel <arend@broadcom.com> +--- + +--- a/drivers/net/wireless/brcm80211/brcmfmac/debug.h ++++ b/drivers/net/wireless/brcm80211/brcmfmac/debug.h +@@ -37,6 +37,7 @@ + #define BRCMF_SDIO_VAL 0x00020000 + #define BRCMF_MSGBUF_VAL 0x00040000 + #define BRCMF_PCIE_VAL 0x00080000 ++#define BRCMF_FWCON_VAL 0x00100000 + + /* set default print format */ + #undef pr_fmt +@@ -78,6 +79,7 @@ do { \ + #define BRCMF_GLOM_ON() (brcmf_msg_level & BRCMF_GLOM_VAL) + #define BRCMF_EVENT_ON() (brcmf_msg_level & BRCMF_EVENT_VAL) + #define BRCMF_FIL_ON() (brcmf_msg_level & BRCMF_FIL_VAL) ++#define BRCMF_FWCON_ON() (brcmf_msg_level & BRCMF_FWCON_VAL) + + #else /* defined(DEBUG) || defined(CPTCFG_BRCM_TRACING) */ + +@@ -90,6 +92,7 @@ do { \ + #define BRCMF_GLOM_ON() 0 + #define BRCMF_EVENT_ON() 0 + #define BRCMF_FIL_ON() 0 ++#define BRCMF_FWCON_ON() 0 + + #endif /* defined(DEBUG) || defined(CPTCFG_BRCM_TRACING) */ + +--- a/drivers/net/wireless/brcm80211/brcmfmac/pcie.c ++++ b/drivers/net/wireless/brcm80211/brcmfmac/pcie.c +@@ -644,7 +644,7 @@ static void brcmf_pcie_bus_console_init( + addr = console->base_addr + BRCMF_CONSOLE_BUFSIZE_OFFSET; + console->bufsize = brcmf_pcie_read_tcm32(devinfo, addr); + +- brcmf_dbg(PCIE, "Console: base %x, buf %x, size %d\n", ++ brcmf_dbg(FWCON, "Console: base %x, buf %x, size %d\n", + console->base_addr, console->buf_addr, console->bufsize); + } + +@@ -656,6 +656,9 @@ static void brcmf_pcie_bus_console_read( + u8 ch; + u32 newidx; + ++ if (!BRCMF_FWCON_ON()) ++ return; ++ + console = &devinfo->shared.console; + addr = console->base_addr + BRCMF_CONSOLE_WRITEIDX_OFFSET; + newidx = brcmf_pcie_read_tcm32(devinfo, addr); +@@ -677,7 +680,7 @@ static void brcmf_pcie_bus_console_read( + } + if (ch == '\n') { + console->log_str[console->log_idx] = 0; +- brcmf_dbg(PCIE, "CONSOLE: %s", console->log_str); ++ pr_debug("CONSOLE: %s", console->log_str); + console->log_idx = 0; + } + } +--- a/drivers/net/wireless/brcm80211/brcmfmac/sdio.c ++++ b/drivers/net/wireless/brcm80211/brcmfmac/sdio.c +@@ -123,6 +123,7 @@ struct rte_console { + + #define BRCMF_FIRSTREAD (1 << 6) + ++#define BRCMF_CONSOLE 10 /* watchdog interval to poll console */ + + /* SBSDIO_DEVICE_CTL */ + +@@ -3204,6 +3205,8 @@ static void brcmf_sdio_debugfs_create(st + if (IS_ERR_OR_NULL(dentry)) + return; + ++ bus->console_interval = BRCMF_CONSOLE; ++ + brcmf_debugfs_add_entry(drvr, "forensics", brcmf_sdio_forensic_read); + brcmf_debugfs_add_entry(drvr, "counters", + brcmf_debugfs_sdio_count_read); +@@ -3613,7 +3616,7 @@ static void brcmf_sdio_bus_watchdog(stru + } + #ifdef DEBUG + /* Poll for console output periodically */ +- if (bus->sdiodev->state == BRCMF_SDIOD_DATA && ++ if (bus->sdiodev->state == BRCMF_SDIOD_DATA && BRCMF_FWCON_ON() && + bus->console_interval != 0) { + bus->console.count += BRCMF_WD_POLL_MS; + if (bus->console.count >= bus->console_interval) { |
