  - drm/amdkfd更正移轉 DMA 對應方向。SVM DMA 裝置對應方向應設定為與 DMA 取消對應設定相同，否則 DMA 核心將報告下列警告。在完成此解決方案之前已討論過此 KFD 移轉案例中的 DMA 對應類型 (資料流型或一致)其後為 https://lore.kernel.org/all/04d4ab32 -45a1-4b88-86ee-fb0f35a0ca40@amd.com/T/。
    由於在存取 的 DMA 緩衝區中沒有 dma_sync_single_for_*()因為此移轉作業應該是正確且自動的同步。請注意在 DMA 同步的多種快取同步原則中未必有效能問題。因此為了簡化 DMA 方向設定對齊讓我們將 DMA 對應方向設定為 BIDIRECTIONAL。 [ 150.834218] 警告CPU8 PID1812在 kernel/dma/debug.c:1028 check_unmap+0x1cc/0x930 [ 150.834225] 連結於 amdgpu(OE) amdxcp drm_exec(OE) gpu_sched drm_buddy(OE) drm_ttm_helper 的模組(OE) ttm(OE) drm_suballoc_helper(OE) drm_display_helper(OE) drm_kms_helper(OE) i2c_algo_bit rpcsec_gss_krb5 auth_rpcgss nfsv4 nfs lockd grace netfs xt_conntrack xt_MASQUERADE nf_conntrack_netlink xfrm_user xfrm_algo iptable_nat xt_addrtype iptable_filter br_netfilter nvme_fabrics overlay nfnetlink_cttimeout nfnetlink openvswitch nsh nf_conncount nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 libcrc32c bridge stp llc sch_fq_codel intel_rapl_msr amd_atl intel_rapl_common snd_hda_codec_realtek snd_hda_codec_generic snd_hda_scodec_component snd_hda_codec_hdmi snd_hda_intel snd_intel_dspcfg edac_mce_amd snd_pci_acp6x snd_hda_codec snd_acp_config snd_hda_core snd_hwdep snd_soc_acpi kvm_amd sunrpc snd_pcm kvm binfmt_misc snd_seq_midi crct10dif_pclmul snd_seq_midi_event ghash_clmulni_intel sha512_ssse3 snd_rawmidi nls_iso8859_1 sha256_ssse3 sha1_ssse3 snd_seq aesni_intel snd_seq_device crypto_simd snd_timer cryptd input_leds [ 150.834310] wmi_bmof serio_raw k10temp rapl snd sp5100_tco ipmi_devintf soundcore ccp ipmi_msghandler cm32181 industrialio mac_hid msr parport_pc ppdev lp parport efi_pstore drm(OE) ip_tables x_tables pci_stub crc32_pclmul nvme ahci libahci i2c_piix4 r8169 nvme_core i2c_designware_pci realtek i2c_ccgx_ucsi video wmi hid_generic cdc_ether usbnet usbhid hid r8152 mii [ 150.834354] CPU8 PID1812 Commrocrtst64 污染G OE 6.10.0-custom #492 [ 150.834358] 硬體名稱AMD Majolica-RN/Majolica-RNBIOS RMJ1009A 2021 年 6 月 13 日 [ 150.834360] RIP 0010:check_unmap+0x1cc/0x930 [ 150.834363] 程式碼c0 4c 89 4d c8 e8 34 bf 86 00 4c 8b 4d c8 4c 8b 45 c0 48 8b 4d b8 48 89 c6 41 57 4c 89 ea 48 c7 c7 80 49 b4 84 e8 b4 81 f3 ff <0f> 0b 48 c7 c7 04 83 ac 84 e8 76 ba fc ff 41 8b 76 4c 49 8d 7e 50 [ 150.834365] RSP
