From e596b90338126d08a8d90f08e79bb644b8c9f2b6 Mon Sep 17 00:00:00 2001 From: Yong Zhao Date: Wed, 20 Sep 2017 18:10:19 -0400 Subject: [PATCH] drm/amdkfd: Reuse CHIP_* from amdgpu v2 There are already CHIP_* definitions under amd_shared.h file on amdgpu side, so KFD should reuse them rather than defining new ones. Using enum for asic type requires default cases on switch statements to prevent compiler warnings. WARN on unsupported ASICs. It should never get there because KFD should not be initialized on unsupported devices. v2: Replace BUG() with WARN and error return Signed-off-by: Yong Zhao Signed-off-by: Felix Kuehling Signed-off-by: Oded Gabbay --- .../drm/amd/amdkfd/kfd_device_queue_manager.c | 4 ++++ drivers/gpu/drm/amd/amdkfd/kfd_kernel_queue.c | 18 ++++++++++++------ drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager.c | 3 +++ drivers/gpu/drm/amd/amdkfd/kfd_priv.h | 9 +++------ 4 files changed, 22 insertions(+), 12 deletions(-) diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c b/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c index 87f8742dcd8c..fe0f0de0ef86 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c +++ b/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager.c @@ -1130,6 +1130,10 @@ struct device_queue_manager *device_queue_manager_init(struct kfd_dev *dev) case CHIP_KAVERI: device_queue_manager_init_cik(&dqm->ops_asic_specific); break; + default: + WARN(1, "Unexpected ASIC family %u", + dev->device_info->asic_family); + goto out_free; } if (!dqm->ops.initialize(dqm)) diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_kernel_queue.c b/drivers/gpu/drm/amd/amdkfd/kfd_kernel_queue.c index d53d32a91a16..8b0c0645d7c0 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_kernel_queue.c +++ b/drivers/gpu/drm/amd/amdkfd/kfd_kernel_queue.c @@ -303,14 +303,20 @@ struct kernel_queue *kernel_queue_init(struct kfd_dev *dev, case CHIP_KAVERI: kernel_queue_init_cik(&kq->ops_asic_specific); break; + default: + WARN(1, "Unexpected ASIC family %u", + dev->device_info->asic_family); + goto out_free; } - if (!kq->ops.initialize(kq, dev, type, KFD_KERNEL_QUEUE_SIZE)) { - pr_err("Failed to init kernel queue\n"); - kfree(kq); - return NULL; - } - return kq; + if (kq->ops.initialize(kq, dev, type, KFD_KERNEL_QUEUE_SIZE)) + return kq; + + pr_err("Failed to init kernel queue\n"); + +out_free: + kfree(kq); + return NULL; } void kernel_queue_uninit(struct kernel_queue *kq) diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager.c b/drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager.c index b1ef1368c3bb..dfd260ef81ff 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager.c +++ b/drivers/gpu/drm/amd/amdkfd/kfd_mqd_manager.c @@ -31,6 +31,9 @@ struct mqd_manager *mqd_manager_init(enum KFD_MQD_TYPE type, return mqd_manager_init_cik(type, dev); case CHIP_CARRIZO: return mqd_manager_init_vi(type, dev); + default: + WARN(1, "Unexpected ASIC family %u", + dev->device_info->asic_family); } return NULL; diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_priv.h b/drivers/gpu/drm/amd/amdkfd/kfd_priv.h index f0ca60f27d9a..5ebe565fecb3 100644 --- a/drivers/gpu/drm/amd/amdkfd/kfd_priv.h +++ b/drivers/gpu/drm/amd/amdkfd/kfd_priv.h @@ -33,6 +33,8 @@ #include #include +#include "amd_shared.h" + #define KFD_SYSFS_FILE_MODE 0444 #define KFD_MMAP_DOORBELL_MASK 0x8000000000000 @@ -112,11 +114,6 @@ enum cache_policy { cache_policy_noncoherent }; -enum asic_family_type { - CHIP_KAVERI = 0, - CHIP_CARRIZO -}; - struct kfd_event_interrupt_class { bool (*interrupt_isr)(struct kfd_dev *dev, const uint32_t *ih_ring_entry); @@ -125,7 +122,7 @@ struct kfd_event_interrupt_class { }; struct kfd_device_info { - unsigned int asic_family; + enum amd_asic_type asic_family; const struct kfd_event_interrupt_class *event_interrupt_class; unsigned int max_pasid_bits; unsigned int max_no_of_hqd;
