The ASIC's CPU is working in LE so when running in a BE host, the driver needs to do the proper endianness swapping when preparing this array. In addition, this patch also fixes the endianness of a couple of kernel log debug messages that print values of packets Signed-off-by: Ben Segal Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay Signed-off-by: Sasha Levin --- drivers/misc/habanalabs/goya/goya.c | 33 +++++++++++++++++++++-------- 1 file changed, 24 insertions(+), 9 deletions(-) diff --git a/drivers/misc/habanalabs/goya/goya.c b/drivers/misc/habanalabs/goya/goya.c index 9216cc3599178..ac6b252a1ddcb 100644 --- a/drivers/misc/habanalabs/goya/goya.c +++ b/drivers/misc/habanalabs/goya/goya.c @@ -3311,9 +3311,11 @@ static int goya_validate_dma_pkt_no_mmu(struct hl_device *hdev, int rc; dev_dbg(hdev->dev, "DMA packet details:\n"); - dev_dbg(hdev->dev, "source == 0x%llx\n", user_dma_pkt->src_addr); - dev_dbg(hdev->dev, "destination == 0x%llx\n", user_dma_pkt->dst_addr); - dev_dbg(hdev->dev, "size == %u\n", user_dma_pkt->tsize); + dev_dbg(hdev->dev, "source == 0x%llx\n", + le64_to_cpu(user_dma_pkt->src_addr)); + dev_dbg(hdev->dev, "destination == 0x%llx\n", + le64_to_cpu(user_dma_pkt->dst_addr)); + dev_dbg(hdev->dev, "size == %u\n", le32_to_cpu(user_dma_pkt->tsize)); ctl = le32_to_cpu(user_dma_pkt->ctl); user_dir = (ctl & GOYA_PKT_LIN_DMA_CTL_DMA_DIR_MASK) >> @@ -3342,9 +3344,11 @@ static int goya_validate_dma_pkt_mmu(struct hl_device *hdev, struct packet_lin_dma *user_dma_pkt) { dev_dbg(hdev->dev, "DMA packet details:\n"); - dev_dbg(hdev->dev, "source == 0x%llx\n", user_dma_pkt->src_addr); - dev_dbg(hdev->dev, "destination == 0x%llx\n", user_dma_pkt->dst_addr); - dev_dbg(hdev->dev, "size == %u\n", user_dma_pkt->tsize); + dev_dbg(hdev->dev, "source == 0x%llx\n", + le64_to_cpu(user_dma_pkt->src_addr)); + dev_dbg(hdev->dev, "destination == 0x%llx\n", + le64_to_cpu(user_dma_pkt->dst_addr)); + dev_dbg(hdev->dev, "size == %u\n", le32_to_cpu(user_dma_pkt->tsize)); /* * WA for HW-23. @@ -3384,7 +3388,8 @@ static int goya_validate_wreg32(struct hl_device *hdev, dev_dbg(hdev->dev, "WREG32 packet details:\n"); dev_dbg(hdev->dev, "reg_offset == 0x%x\n", reg_offset); - dev_dbg(hdev->dev, "value == 0x%x\n", wreg_pkt->value); + dev_dbg(hdev->dev, "value == 0x%x\n", + le32_to_cpu(wreg_pkt->value)); if (reg_offset != (mmDMA_CH_0_WR_COMP_ADDR_LO & 0x1FFF)) { dev_err(hdev->dev, "WREG32 packet with illegal address 0x%x\n", @@ -4252,6 +4257,8 @@ static int goya_unmask_irq_arr(struct hl_device *hdev, u32 *irq_arr, size_t total_pkt_size; long result; int rc; + int irq_num_entries, irq_arr_index; + __le32 *goya_irq_arr; total_pkt_size = sizeof(struct armcp_unmask_irq_arr_packet) + irq_arr_size; @@ -4269,8 +4276,16 @@ static int goya_unmask_irq_arr(struct hl_device *hdev, u32 *irq_arr, if (!pkt) return -ENOMEM; - pkt->length = cpu_to_le32(irq_arr_size / sizeof(irq_arr[0])); - memcpy(&pkt->irqs, irq_arr, irq_arr_size); + irq_num_entries = irq_arr_size / sizeof(irq_arr[0]); + pkt->length = cpu_to_le32(irq_num_entries); + + /* We must perform any necessary endianness conversation on the irq + * array being passed to the goya hardware + */ + for (irq_arr_index = 0, goya_irq_arr = (__le32 *) &pkt->irqs; + irq_arr_index < irq_num_entries ; irq_arr_index++) + goya_irq_arr[irq_arr_index] = + cpu_to_le32(irq_arr[irq_arr_index]); pkt->armcp_pkt.ctl = cpu_to_le32(ARMCP_PACKET_UNMASK_RAZWI_IRQ_ARRAY << ARMCP_PKT_CTL_OPCODE_SHIFT); -- 2.20.1
