10 years agotarget-arm: Fix errors in writes to generic timer control registers
Peter Maydell [Mon, 9 Jun 2014 14:43:26 +0000 (15:43 +0100)]
target-arm: Fix errors in writes to generic timer control registers

The code for handling writes to the generic timer control registers
had several bugs:
 * ISTATUS (bit 2) is read-only but we forced it to zero on any write
 * the check for "was IMASK (bit 1) toggled?" incorrectly used '&' where
   it should be '^'
 * the handling of IMASK was inverted: we should set the IRQ if
   ISTATUS is set and IMASK is clear, not if both are set

The combination of these bugs meant that when running a Linux guest
that uses the generic timers we would fairly quickly end up either
forgetting that the timer output should be asserted, or failing to
set the IRQ when the timer was unmasked. The result is that the guest
never gets any more timer interrupts.

2. user creates a snapshot of the VDI before the write request is completed

4. the driver reload an inode object of the new active VDI, then issues a write
   request again
5. the second write request can be completed
6. driver decide the request is COW or not with the below conditional branch:
      if (s->inode.data_vdi_id[idx] != s->inode.vdi_id) {
7. the ID of the written object and VID of the new active VDI is different, so
   the driver updates data_vdi_id[idx] and writes inode object

10 years agoqdev: Display warning about unused -global

qdev: Display warning about unused -global

For example: with "-vga cirrus"; "-global vga.vgamem_mb=16" is just
ignored when "-global cirrus-vga.vgamem_mb=16" is not.

This is currently clear when the wrong property is provided:
