From bc23ca35cfb18b0a98afa42de1df1efc7e2e9f8f Mon Sep 17 00:00:00 2001 From: Jeeja KP Date: Fri, 11 Mar 2016 10:12:53 +0530 Subject: ASoC: Intel: Skylake: Move Skylake dsp ops & loader ops The code loading for Skylake and other platforms is different, so add a dsp_ops and a loader_ops which can be defined for each platform. Move the dsp init, cleanup and loader ops (alloc and free dma) to these ops Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul Signed-off-by: Mark Brown --- sound/soc/intel/skylake/skl-messages.c | 62 +++++++++++++++++++++++++++++----- sound/soc/intel/skylake/skl.h | 12 ++++++- 2 files changed, 64 insertions(+), 10 deletions(-) (limited to 'sound/soc/intel') diff --git a/sound/soc/intel/skylake/skl-messages.c b/sound/soc/intel/skylake/skl-messages.c index 737934cc620d..79c5089b85d6 100644 --- a/sound/soc/intel/skylake/skl-messages.c +++ b/sound/soc/intel/skylake/skl-messages.c @@ -72,17 +72,47 @@ static void skl_dsp_enable_notification(struct skl_sst *ctx, bool enable) skl_ipc_set_large_config(&ctx->ipc, &msg, (u32 *)&mask); } +static struct skl_dsp_loader_ops skl_get_loader_ops(void) +{ + struct skl_dsp_loader_ops loader_ops; + + memset(&loader_ops, 0, sizeof(struct skl_dsp_loader_ops)); + + loader_ops.alloc_dma_buf = skl_alloc_dma_buf; + loader_ops.free_dma_buf = skl_free_dma_buf; + + return loader_ops; +}; + +static const struct skl_dsp_ops dsp_ops[] = { + { + .id = 0x9d70, + .loader_ops = skl_get_loader_ops, + .init = skl_sst_dsp_init, + .cleanup = skl_sst_dsp_cleanup + }, +}; + +static int skl_get_dsp_ops(int pci_id) +{ + int i; + + for (i = 0; i < ARRAY_SIZE(dsp_ops); i++) { + if (dsp_ops[i].id == pci_id) + return i; + } + + return -EINVAL; +} + int skl_init_dsp(struct skl *skl) { void __iomem *mmio_base; struct hdac_ext_bus *ebus = &skl->ebus; struct hdac_bus *bus = ebus_to_hbus(ebus); - int irq = bus->irq; struct skl_dsp_loader_ops loader_ops; - int ret; - - loader_ops.alloc_dma_buf = skl_alloc_dma_buf; - loader_ops.free_dma_buf = skl_free_dma_buf; + int irq = bus->irq; + int ret, index; /* enable ppcap interrupt */ snd_hdac_ext_bus_ppcap_enable(&skl->ebus, true); @@ -95,8 +125,14 @@ int skl_init_dsp(struct skl *skl) return -ENXIO; } - ret = skl_sst_dsp_init(bus->dev, mmio_base, irq, + index = skl_get_dsp_ops(skl->pci->device); + if (index < 0) + return -EINVAL; + + loader_ops = dsp_ops[index].loader_ops(); + ret = dsp_ops[index].init(bus->dev, mmio_base, irq, skl->fw_name, loader_ops, &skl->skl_sst); + if (ret < 0) return ret; @@ -106,18 +142,26 @@ int skl_init_dsp(struct skl *skl) return ret; } -void skl_free_dsp(struct skl *skl) +int skl_free_dsp(struct skl *skl) { struct hdac_ext_bus *ebus = &skl->ebus; struct hdac_bus *bus = ebus_to_hbus(ebus); - struct skl_sst *ctx = skl->skl_sst; + struct skl_sst *ctx = skl->skl_sst; + int index; /* disable ppcap interrupt */ snd_hdac_ext_bus_ppcap_int_enable(&skl->ebus, false); - skl_sst_dsp_cleanup(bus->dev, ctx); + index = skl_get_dsp_ops(skl->pci->device); + if (index < 0) + return -EIO; + + dsp_ops[index].cleanup(bus->dev, ctx); + if (ctx->dsp->addr.lpe) iounmap(ctx->dsp->addr.lpe); + + return 0; } int skl_suspend_dsp(struct skl *skl) diff --git a/sound/soc/intel/skylake/skl.h b/sound/soc/intel/skylake/skl.h index 1ca1911f1587..39e16fa7a92b 100644 --- a/sound/soc/intel/skylake/skl.h +++ b/sound/soc/intel/skylake/skl.h @@ -90,6 +90,16 @@ struct skl_dma_params { u8 stream_tag; }; +struct skl_dsp_ops { + int id; + struct skl_dsp_loader_ops (*loader_ops)(void); + int (*init)(struct device *dev, void __iomem *mmio_base, + int irq, const char *fw_name, + struct skl_dsp_loader_ops loader_ops, + struct skl_sst **skl_sst); + void (*cleanup)(struct device *dev, struct skl_sst *ctx); +}; + int skl_platform_unregister(struct device *dev); int skl_platform_register(struct device *dev); @@ -100,7 +110,7 @@ struct nhlt_specific_cfg *skl_get_ep_blob(struct skl *skl, u32 instance, int skl_nhlt_update_topology_bin(struct skl *skl); int skl_init_dsp(struct skl *skl); -void skl_free_dsp(struct skl *skl); +int skl_free_dsp(struct skl *skl); int skl_suspend_dsp(struct skl *skl); int skl_resume_dsp(struct skl *skl); #endif /* __SOUND_SOC_SKL_H */ -- cgit v1.2.3
