2012-10-13target-sparc: Don't compute full flags value so oftenRichard Henderson4-19/+26
Avoid speculatively computing flags before every potentially trapping operation and instead do the flags computation when a trap actually occurs. This gives approximately 30% speedup in emulation. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2012-10-12arm_gic: Rename gic_state to GICStatePeter Maydell4-43/+43
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. Crosthwaite1-1/+1
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 Maydell1-5/+22
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 Maydell1-20/+21
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 Maydell1-17/+42
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 Maydell1-7/+13
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 Brinkmann1-1/+1
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 Goede1-1/+9
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.

Allow multiple qdev_init_gpio_in() calls for the one device. The first call will define GPIOs 0-N-1, the next GPIOs N- ... . Allows different GPIOs to be handled with different handlers.

Removed assertion that only one device is attached to the SSI bus. When multiple devices are attached, all slaves have their transfer function called for transfers. Each device is responsible for knowing whether or not its CS is active, and if not returning 0. The returned data is the logical or of all responses from the (mulitple) devices.

2012-10-09qemu-ga: use state dir from CONFIG_QEMU_LOCALSTATEDIRLuiz Capitulino1-2/+2
Has the side effect of changing the default directory used to save the freeze status file from /tmp to ${prefix}/var/run. This is a beneficial change for two reasons: 1. FHS states that programs must not assume that files in /tmp will still exist between invocations of the program. This defeats the purpose of the freeze status file 2. FHS dictates that /var/run must be cleaned on boot, this ensures that a stale freeze status file will be removed on boot Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Reviewed-by: Michael Roth <mdroth@linux.vnet.ibm.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>

Blue Swirl reports that Clang doesn't like the structure we define to avoid dynamic allocation for a number of calls to VFIO_DEVICE_SET_IRQS. Adding an element after a variable sized type is a GNU extension. Switch back to dynamic allocation, which really isn't a problem since this is only done on interrupt setup changes.
