2012-10-17virtio-net: use qemu_get_buffer() in a temp bufferJuan Quintela
qemu_fseek() is known to be wrong. Would be removed on the next commit. This code should never been used (value has been MAC_TABLE_ENTRIES since 2009). Signed-off-by: Juan Quintela <quintela@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>
2012-10-17i440fx: avoid destroying memory regions within a transactionAvi Kivity
Calling memory_region_destroy() within a transaction is illegal, since the memory API is allowed to continue to dispatch to a region until the transaction commits. 440fx does that however when managing PAM registers. This bug is benign, since the regions are all aliases (which the memory core tends to throw anyway), and since we don't do concurrent dispatch yet, but instead of relying on that, tighten ship ahead of the coming concurrency storm. Fix by having a predefined set of regions, of which one will be enabled at any time. Signed-off-by: Avi Kivity <avi@redhat.com>

2012-10-15xen_pt: use separate MemoryListeners for memory and I/OAvi Kivity
Using an unfiltered memory listener will cause regions to be reported fails multiple times if we have more than two address spaces. Use a separate listener for memory and I/O, and utilize MemoryListener's address space filtering to fix this. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15vhost: use MemoryListener filtering to only monitor RAM address spaceAvi Kivity
Instead of checking manually, let the listener filter for us. This prepares us for DMA address spaces. Signed-off-by: Avi Kivity <avi@redhat.com>

Rename the gic_state struct to match QEMU's coding style conventions for structure names, since the impending KVM-for-ARM patches will create another subclass of it.

2012-10-12zynq_slcr: Fixed ResetValues enumPeter A. G. Crosthwaite
There is a gap in the reset region of the address space at offset 0x208. This throws out all these enum values by one when translating them to address offsets.

2012-10-12hw/ds1338: Implement state save/restorePeter Maydell
Implement state save/restore for the DS1338. This requires the usual minor adjustment of types in the state struct to get fixed-width ones with vmstate macros. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-12hw/ds1338: Remove 'now' field from state structPeter Maydell
The 'struct tm now' field in the state structure is in fact only ever used as a temporary (the actual RTC state is held in 'offset'). Remove it from the state structure in favour of using local variables to avoid confusion about whether it needs to be saved on migration. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-12hw/ds1338: Recapture current time when register pointer wraps aroundPeter Maydell
The DS1338 datasheet documents that the current time is captured into the secondary registers when the register pointer wraps round to zero as well as at a START condition. Implement this. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-12hw/ds1338: Fix mishandling of register pointerPeter Maydell
Correct several deficiencies in the handling of the register pointer: * it should wrap around after 0x3f, not 0xff * guard against the caller handing us an out of range pointer (on h/w this can never happen, because only a 7 bit value is transferred over the I2C bus) * there was confusion over whether nvram[] holds only the 56 bytes of guest-accessible NVRAM, or also the secondary registers which hold the value of the clock captured at the start of a multibyte read. Correct to consistently be the latter, by fixing the array size and the offset used for NVRAM writes. * ds1338_send was attempting to use 'data' as both the data and the register offset simultaneously, which meant that writes to any register were broken; fix to use the register pointer.

2012-10-12cadence_ttc: Fix 'clear on read' behaviorSoren Brinkmann
A missing call to qemu_set_irq() when reading the IRQ register required SW to write to the IRQ register to acknowledge an interrupt. With this patch the behavior is fixed: - Reading the interrupt register clears it and updates the timers interrupt status - Writes to the interrupt register are ignored Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com> Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-10-11uhci: Raise interrupt when requested even for non active tdsHans de Goede
According to the spec we must raise an interrupt when one is requested even for non active tds. Linux depends on this, for bulk transfers it runs an inactivity timer to work around a bug in early uhci revisions, when we take longer then 200 ms to process a packet, this timer goes of, and as part of the handling Linux then unlinks the qh, and relinks it after the frindex has increased by atleast 1, the problem is Linux only checks for the frindex increases on an interrupt, and we don't send that, causing the qh to go inactive for more then 32 frames, at which point we consider the packet cancelled.
