As per our understanding, Till ACP firmware starts responding to the driver's IPC messages, FW won't acquire the HW lock. Adding delay in post_fw_run() callback seems to not a correct solution, as there are no IPC messages will be sent from host till FW boot ready is received. Is fail to acquire the HW lock is for first host IPC message? > > Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea(a)collabora.com> > --- > sound/soc/sof/amd/acp.c | 1 + > sound/soc/sof/amd/acp.h | 1 + > sound/soc/sof/amd/vangogh.c | 18 ++++++++++++++++++ > 3 files changed, 20 insertions(+) > > diff --git a/sound/soc/sof/amd/acp.c b/sound/soc/sof/amd/acp.c > index 33648ff8b83365e76d7d90e52c2cb8f884a2fe72..9e13c96528be3371e063072513c118cfc8b93fe8 100644 > --- a/sound/soc/sof/amd/acp.c > +++ b/sound/soc/sof/amd/acp.c > @@ -27,6 +27,7 @@ MODULE_PARM_DESC(enable_fw_debug, "Enable Firmware debug"); > static struct acp_quirk_entry quirk_valve_galileo = { > .signed_fw_image = true, > .skip_iram_dram_size_mod = true, > + .post_fw_run_delay = true, > }; > > const struct dmi_system_id acp_sof_quirk_table[] = { > diff --git a/sound/soc/sof/amd/acp.h b/sound/soc/sof/amd/acp.h > index 800594440f73914e7b8ccaf86369ac686e1da630..2a19d82d6200223cdfccd49fbcf1b52968ae1230 100644 > --- a/sound/soc/sof/amd/acp.h > +++ b/sound/soc/sof/amd/acp.h > @@ -220,6 +220,7 @@ struct sof_amd_acp_desc { > struct acp_quirk_entry { > bool signed_fw_image; > bool skip_iram_dram_size_mod; > + bool post_fw_run_delay; > }; > > /* Common device data struct for ACP devices */ > diff --git a/sound/soc/sof/amd/vangogh.c b/sound/soc/sof/amd/vangogh.c > index 8e2672106ac60a22824836a944503a05616f8661..d5f1dddd43e72dd62b3d031130193e6125edf9df 100644 > --- a/sound/soc/sof/amd/vangogh.c > +++ b/sound/soc/sof/amd/vangogh.c > @@ -11,6 +11,7 @@ > * Hardware interface for Audio DSP on Vangogh platform > */ > > +#include <linux/delay.h> > #include <linux/platform_device.h> > #include <linux/module.h> > > @@ -136,6 +137,20 @@ static struct snd_soc_dai_driver vangogh_sof_dai[] = { > }, > }; > > +static int sof_vangogh_post_fw_run_delay(struct snd_sof_dev *sdev) > +{ > + /* > + * Resuming from suspend in some cases my cause the DSP firmware > + * to enter an unrecoverable faulty state.
