Let me read through the report carefully. + +The issue is with the intel-hda component in QEMU, specifically regarding the stream reset bits being broken. The user provided a detailed description from the HD audio spec, explaining how the Stream Reset bit should work. According to the spec, when you write a 1 to this bit, it triggers a reset, and the hardware reports back a 1 until it's done resetting, then it goes back to 0. Software needs to read these bits to verify the state. + +However, in the current QEMU code, after setting the stream control (st->ctl) with SD_STS_FIFO_READY shifted left by 24 bits, the bit immediately becomes 0 instead of remaining 1 during the reset process. This causes the driver to either timeout or hang because it never sees the bit as 1. + +Looking at the provided code snippet from intel-hda.c: + +if (st->ctl & 0x01) { + /* reset */ + dprint(d, 1, "st #%d: reset\n", reg->stream); + st->ctl = SD_STS_FIFO_READY << 24; +} + +So when a reset is requested by setting the bit to 1, the code immediately sets st->ctl to a value that makes the bit 0. This doesn't align with how real hardware behaves, where the bit transitions from 1 to 0 after reset completion. + +Now, considering the possible categories: mistranslation, assembly lowering, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor, or other. + +This bug is related to how a specific hardware component (intel-hda) in QEMU handles stream resets. The issue arises from incorrect handling of the reset bit in the code, leading to improper state reporting. This seems to be a problem with the device's emulation not adhering to the specifications, causing it to misbehave compared to real hardware. + +Therefore, the most fitting category is 'device' because it pertains to how a specific hardware component (intel-hda) is being emulated incorrectly in QEMU. +</think> + +The bug report describes an issue with the intel-hda device emulation where the stream reset bits are not functioning as per the specification. The problem lies in the incorrect handling of these bits, leading to improper state transitions which cause the driver to malfunction.
