A reset can therefore leave stale\ndeferred bits behind, and migration can silently drop them.\n\nClear pending_intr_sts on reset and include it in VMState while keeping\ncompatibility with older migration streams.\n\nFixes: 7e82393ed058 (\"hw/i2c/aspeed: fix lost interrupts on back-to-back commands\")\nSigned-off-by: GuoHan Zhao <zhaoguohan@kylinos.cn>\n---\n hw/i2c/aspeed_i2c.c | 4 +++-\n 1 file changed, 3 insertions(+), 1 deletion(-)", "diff": "diff --git a/hw/i2c/aspeed_i2c.c b/hw/i2c/aspeed_i2c.c\nindex 5d18f8d49ea4..90f83a03fd4f 100644\n--- a/hw/i2c/aspeed_i2c.c\n+++ b/hw/i2c/aspeed_i2c.c\n@@ -1134,10 +1134,11 @@ static const MemoryRegionOps aspeed_i2c_bus_pool_ops = {\n \n static const VMStateDescription aspeed_i2c_bus_vmstate = {\n .name = TYPE_ASPEED_I2C,\n- .version_id = 6,\n+ .version_id = 7,\n .minimum_version_id = 6,\n .fields = (const VMStateField[]) {\n VMSTATE_UINT32_ARRAY(regs, AspeedI2CBus, ASPEED_I2C_NEW_NUM_REG),\n+ VMSTATE_UINT32_V(pending_intr_sts, AspeedI2CBus, 7),\n VMSTATE_UINT8_ARRAY(pool, AspeedI2CBus, ASPEED_I2C_BUS_POOL_SIZE),\n VMSTATE_UINT64(dma_dram_offset, AspeedI2CBus),\n VMSTATE_END_OF_LIST()\n@@ -1510,6 +1511,7 @@ static void aspeed_i2c_bus_reset(DeviceState *dev)\n AspeedI2CBus *s = ASPEED_I2C_BUS(dev);\n \n memset(s->regs, 0, sizeof(s->regs));\n+ s->pending_intr_sts = 0;\n i2c_end_transfer(s->bus);\n }\n \n", "prefixes": [] }
