From df4473fadcfe53fcab212b167f4df20bbeb175db Mon Sep 17 00:00:00 2001 From: Sai Prakash Ranjan Date: Thu, 29 Aug 2019 14:28:28 -0600 Subject: coresight: cpu-debug: Add support for Qualcomm Kryo Add support for coresight CPU debug module on Qualcomm Kryo CPUs. This patch adds the UCI entries for Kryo CPUs found on MSM8996 which shares the same PIDs as ETMs. Without this, below error is observed on MSM8996: [ 5.429867] OF: graph: no port node found in /soc/debug@3810000 [ 5.429938] coresight-etm4x: probe of 3810000.debug failed with error -22 [ 5.435415] coresight-cpu-debug 3810000.debug: Coresight debug-CPU0 initialized [ 5.446474] OF: graph: no port node found in /soc/debug@3910000 [ 5.448927] coresight-etm4x: probe of 3910000.debug failed with error -22 [ 5.454681] coresight-cpu-debug 3910000.debug: Coresight debug-CPU1 initialized [ 5.487765] OF: graph: no port node found in /soc/debug@3a10000 [ 5.488007] coresight-etm4x: probe of 3a10000.debug failed with error -22 [ 5.493024] coresight-cpu-debug 3a10000.debug: Coresight debug-CPU2 initialized [ 5.501802] OF: graph: no port node found in /soc/debug@3b10000 [ 5.512901] coresight-etm4x: probe of 3b10000.debug failed with error -22 [ 5.513192] coresight-cpu-debug 3b10000.debug: Coresight debug-CPU3 initialized Signed-off-by: Sai Prakash Ranjan Tested-by: Leo Yan Signed-off-by: Mathieu Poirier Link: https://lore.kernel.org/r/20190829202842.580-4-mathieu.poirier@linaro.org Signed-off-by: Greg Kroah-Hartman --- drivers/hwtracing/coresight/coresight-cpu-debug.c | 33 +++++++++++------------ 1 file changed, 16 insertions(+), 17 deletions(-) (limited to 'drivers/hwtracing/coresight/coresight-cpu-debug.c') diff --git a/drivers/hwtracing/coresight/coresight-cpu-debug.c b/drivers/hwtracing/coresight/coresight-cpu-debug.c index 2463aa7ab4f6..96544b348c27 100644 --- a/drivers/hwtracing/coresight/coresight-cpu-debug.c +++ b/drivers/hwtracing/coresight/coresight-cpu-debug.c @@ -646,24 +646,23 @@ static int debug_remove(struct amba_device *adev) return 0; } +static const struct amba_cs_uci_id uci_id_debug[] = { + { + /* CPU Debug UCI data */ + .devarch = 0x47706a15, + .devarch_mask = 0xfff0ffff, + .devtype = 0x00000015, + } +}; + static const struct amba_id debug_ids[] = { - { /* Debug for Cortex-A53 */ - .id = 0x000bbd03, - .mask = 0x000fffff, - }, - { /* Debug for Cortex-A57 */ - .id = 0x000bbd07, - .mask = 0x000fffff, - }, - { /* Debug for Cortex-A72 */ - .id = 0x000bbd08, - .mask = 0x000fffff, - }, - { /* Debug for Cortex-A73 */ - .id = 0x000bbd09, - .mask = 0x000fffff, - }, - { 0, 0 }, + CS_AMBA_ID(0x000bbd03), /* Cortex-A53 */ + CS_AMBA_ID(0x000bbd07), /* Cortex-A57 */ + CS_AMBA_ID(0x000bbd08), /* Cortex-A72 */ + CS_AMBA_ID(0x000bbd09), /* Cortex-A73 */ + CS_AMBA_UCI_ID(0x000f0205, uci_id_debug), /* Qualcomm Kryo */ + CS_AMBA_UCI_ID(0x000f0211, uci_id_debug), /* Qualcomm Kryo */ + {}, }; static struct amba_driver debug_driver = { -- cgit v1.2.3
