From b0bd0a92b8158ea9c809d885e0f0c21518bdbd14 Mon Sep 17 00:00:00 2001 From: Srinivasan Shanmugam Date: Tue, 25 Jul 2023 18:34:49 +0530 Subject: [PATCH] drm/amdgpu: Prefer dev_* variant over printk in amdgpu_atpx_handler.c MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Changed from printk to dev_* variants so that we get better debug info when there are multiple GPUs in the system. Fixes other style issue: ERROR: open brace '{' following function definitions go on the next line WARNING: printk() should include KERN_ facility level Cc: Christian König Cc: Alex Deucher Signed-off-by: Srinivasan Shanmugam Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher --- drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c | 35 ++++++++++++++++-------- 1 file changed, 23 insertions(+), 12 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c index d6d986b..6f241c5 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_atpx_handler.c @@ -74,24 +74,29 @@ struct atpx_mux { u16 mux; } __packed; -bool amdgpu_has_atpx(void) { +bool amdgpu_has_atpx(void) +{ return amdgpu_atpx_priv.atpx_detected; } -bool amdgpu_has_atpx_dgpu_power_cntl(void) { +bool amdgpu_has_atpx_dgpu_power_cntl(void) +{ return amdgpu_atpx_priv.atpx.functions.power_cntl; } -bool amdgpu_is_atpx_hybrid(void) { +bool amdgpu_is_atpx_hybrid(void) +{ return amdgpu_atpx_priv.atpx.is_hybrid; } -bool amdgpu_atpx_dgpu_req_power_for_displays(void) { +bool amdgpu_atpx_dgpu_req_power_for_displays(void) +{ return amdgpu_atpx_priv.atpx.dgpu_req_power_for_displays; } #if defined(CONFIG_ACPI) -void *amdgpu_atpx_get_dhandle(void) { +void *amdgpu_atpx_get_dhandle(void) +{ return amdgpu_atpx_priv.dhandle; } #endif @@ -113,6 +118,8 @@ static union acpi_object *amdgpu_atpx_call(acpi_handle handle, int function, union acpi_object atpx_arg_elements[2]; struct acpi_object_list atpx_arg; struct acpi_buffer buffer = { ACPI_ALLOCATE_BUFFER, NULL }; + struct acpi_device *adev = container_of(handle, struct acpi_device, handle); + struct device *dev = &adev->dev; atpx_arg.count = 2; atpx_arg.pointer = &atpx_arg_elements[0]; @@ -134,8 +141,8 @@ static union acpi_object *amdgpu_atpx_call(acpi_handle handle, int function, /* Fail only if calling the method fails and ATPX is supported */ if (ACPI_FAILURE(status) && status != AE_NOT_FOUND) { - printk("failed to evaluate ATPX got %s\n", - acpi_format_exception(status)); + dev_err(dev, "failed to evaluate ATPX got %s\n", + acpi_format_exception(status)); kfree(buffer.pointer); return NULL; } @@ -176,6 +183,8 @@ static void amdgpu_atpx_parse_functions(struct amdgpu_atpx_functions *f, u32 mas static int amdgpu_atpx_validate(struct amdgpu_atpx *atpx) { u32 valid_bits = 0; + struct acpi_device *adev = container_of(atpx->handle, struct acpi_device, handle); + struct device *dev = &adev->dev; if (atpx->functions.px_params) { union acpi_object *info; @@ -190,7 +199,7 @@ static int amdgpu_atpx_validate(struct amdgpu_atpx *atpx) size = *(u16 *) info->buffer.pointer; if (size < 10) { - printk("ATPX buffer is too small: %zu\n", size); + dev_err(dev, "ATPX buffer is too small: %zu\n", size); kfree(info); return -EINVAL; } @@ -223,11 +232,11 @@ static int amdgpu_atpx_validate(struct amdgpu_atpx *atpx) atpx->is_hybrid = false; if (valid_bits & ATPX_MS_HYBRID_GFX_SUPPORTED) { if (amdgpu_atpx_priv.quirks & AMDGPU_PX_QUIRK_FORCE_ATPX) { - printk("ATPX Hybrid Graphics, forcing to ATPX\n"); + dev_info(dev, "ATPX Hybrid Graphics, forcing to ATPX\n"); atpx->functions.power_cntl = true; atpx->is_hybrid = false; } else { - printk("ATPX Hybrid Graphics\n"); + dev_info(dev, "ATPX Hybrid Graphics\n"); /* * Disable legacy PM methods only when pcie port PM is usable, * otherwise the device might fail to power off or power on. @@ -260,6 +269,8 @@ static int amdgpu_atpx_verify_interface(struct amdgpu_atpx *atpx) struct atpx_verify_interface output; size_t size; int err = 0; + struct acpi_device *adev = container_of(atpx->handle, struct acpi_device, handle); + struct device *dev = &adev->dev; info = amdgpu_atpx_call(atpx->handle, ATPX_FUNCTION_VERIFY_INTERFACE, NULL); if (!info) @@ -278,8 +289,8 @@ static int amdgpu_atpx_verify_interface(struct amdgpu_atpx *atpx) memcpy(&output, info->buffer.pointer, size); /* TODO: check version? */ - printk("ATPX version %u, functions 0x%08x\n", - output.version, output.function_bits); + dev_info(dev, "ATPX version %u, functions 0x%08x\n", + output.version, output.function_bits); amdgpu_atpx_parse_functions(&atpx->functions, output.function_bits); -- 2.7.4
