From: Ray Wu <ray.wu(a)amd.com> [Why] Different platforms use differnet NBIO header files, causing display code to use differnt offset and read wrong accelerated status.

[PATCH v2] net: macb: Relocate mog_init_rings() callback from macb_mac_link_up() to macb_open()

by Xiaolei Wang

In the non-RT kernel, local_bh_disable() merely disables preemption, whereas it maps to an actual spin lock in the RT kernel. Consequently, when attempting to refill RX buffers via netdev_alloc_skb() in macb_mac_link_up(), a deadlock scenario arises as follows: Chain caused by macb_mac_link_up(): &bp->lock --> (softirq_ctrl.lock) Chain caused by macb_start_xmit(): (softirq_ctrl.lock) --> _xmit_ETHER#2 --> &bp->lock Notably, invoking the mog_init_rings() callback upon link establishment is unnecessary. Instead, we can exclusively call mog_init_rings() within the ndo_open() callback. This adjustment resolves the deadlock issue. Given that mog_init_rings() is only applicable to non-MACB_CAPS_MACB_IS_EMAC cases, we can simply move it to macb_open() and simultaneously eliminate the MACB_CAPS_MACB_IS_EMAC check.

[PATCH] wifi: ath11k: fix qmi memory allocation logic for CALDB region

by Alexandru Gagniuc

Memory region assignment in ath11k_qmi_assign_target_mem_chunk() assumes that: 1. firmware will make a HOST_DDR_REGION_TYPE request, and 2. this request is processed before CALDB_MEM_REGION_TYPE In this case CALDB_MEM_REGION_TYPE, can safely be assigned immediately after the host region. However, if the HOST_DDR_REGION_TYPE request is not made, or the reserved-memory node is not present, then res.start and res.end are 0, and host_ddr_sz remains uninitialized. The physical address should fall back to ATH11K_QMI_CALDB_ADDRESS. That doesn't happen: resource_size(&res) returns 1 for an empty resource, and thus the if clause never takes the fallback path. ab->qmi.target_mem[idx].paddr is assigned the uninitialized value of host_ddr_sz + 0 (res.start). Use "if (res.end > res.start)" for the predicate, which correctly falls back to ATH11K_QMI_CALDB_ADDRESS.

[PATCH v3 01/10] crypto: virtio: Add spinlock protection with virtqueue notification

by Bibo Mao

When VM boots with one virtio-crypto PCI device and builtin backend, run openssl benchmark command with multiple processes, such as openssl speed -evp aes-128-cbc -engine afalg -seconds 10 -multi 32 openssl processes will hangup and there is error reported like this: virtio_crypto virtio0: dataq.0:id 3 is not a head! It seems that the data virtqueue need protection when it is handled for virtio done notification. If the spinlock protection is added in virtcrypto_done_task(), openssl benchmark with multiple processes works well.
