This version of the patch adds new option "werror" to -drive flag. Possible values are: report - report errors to a guest as IO errors ignore - continue as if nothing happened stop - stop VM on any error and retry last command on resume enospc - stop vm on ENOSPC error and retry last command on resume all other errors are reported to a guest.

2009-01-08IDE: Return zero when reading error register with slave selected (Justin ↵aliguori1-1/+2
Chevrier) During hardware detection Openserver issues commands to slaves on both primary and secondary ports. We already return a zero for the status register in this situation but after reading the status register the Openserver installer proceeds to check the value of the error register. Currently we return the existing value in the register. This confuses the installer and it tries to access the slave units later on. When the command that gets issued later gets ignored the installer freezes. The patch below returns zero when reading the error register if a slave unit is selected. Openserver can now successfully be installed using the emulated IDE hard drive.

This patch adds emulation for a CompactFlash on sh4/r2d board. The device is CF, but wired to be worked as True-IDE mode, and connected directly to SH bus. So, this code is to support generally mmio based IDEs which are supported by "pata_platform" driver in linux kernel.

2008-11-19Fix media detection on emulated CDROM (Gary Grebus)aliguori1-1/+3
This patch tweaks the ATAPI CDROM emulation to fix an annoyance seen when running a variety of Linux guests: the desktop GUI shows a CDROM device as present, but is unable to automount the media and display its contents. The patch adds the PLAY_AUDIO capability bit to the data returned by MODE_SENSE commands. That convinces the guest kernel to determine what kind of media is present. Arguably Linux could be smarter about this, but it's my guess there are few (if any) hardware CDROM drives that don't set the bit, and there are a large number of Linux distros that exhibit this problem.

The DIAGNOSE command in the qemu IDE implementation has an error when use dfor packet devices. The status register value is dependant on the drive being a packet device or not, this patch corrects the returned status. From the ATA/PI specification (V6 draft): "If the device implements the PACKET command feature set, the device SHALL clear bits 6,5,4,3,2 and 0 in the Status register to zero." A selection of physical devices have been checked and do conform to the specifications behaviour.
