The report mentions that the stream reset bits are broken because when you set them, they don't read back as 1. This is causing timeouts or hangs in the driver. + +Looking at the code provided from intel-hda.c, specifically the function intel_hda_set_st_ctl(), it seems like whenever the control bit (st->ctl) has the least significant bit set (0x01), it's supposed to trigger a reset. But according to the code, when that happens, st->ctl is immediately set to SD_STS_FIFO_READY shifted left by 24 bits. So instead of setting the stream reset bit to 1 and keeping it there until hardware reports back, the code just sets it to 0 right away. + +The user compared this behavior with real hardware, which correctly follows the spec: writing a 1 causes the bit to stay at 1 until the hardware is in reset. So QEMU's emulation isn't matching that, causing issues for drivers that expect the correct sequence of bits being set and cleared. + +Now, thinking about whether this is user-mode or system-mode related. System-mode bugs typically involve lower-level operations like device drivers, kernel code, peripherals, etc., which have higher privileges. Since this issue involves emulating hardware (Intel HDA) in QEMU, which interacts with the virtual machine's OS at a low level, it seems to fall under system-mode. The problem affects how the audio subsystem is handled, which is part of the system's device drivers and not something that would be managed in user applications. + +Therefore, this bug is related to system-mode operations. +</think> + +system \ No newline at end of file |
