2012-03-19vnc: Fix packed boolean struct membersStefan Weil
This patch fixes warnings reported by splint: For variables which are packed in a single bit, a signed data type like 'int' does not make much sense. There is no obvious reason why the two values should be packed, so I removed the packing and changed the data type to bool because both are used as boolean values. v2: Some versions of gcc complain after this modification, for example gcc (Debian 4.4.5-8) 4.4.5): ui/vnc-auth-sasl.c: In function ‘vnc_sasl_client_cleanup’: ui/vnc-auth-sasl.c:34: error: suggest parentheses around assignment used as truth value Obviously, the compiler does not like code which does bool = unsigned = bool = 0 Splitting that code in three statements works.

2012-03-17w64: Fix data type of next_tb and tcg_qemu_tb_execStefan Weil
next_tb is the numeric value of a tcg target (= QEMU host) address. Using tcg_target_ulong instead of unsigned long shows this and makes the code portable for hosts with an unusual size of long (w64). The type cast '(long)(next_tb & ~3)' was not needed (casting unsigned long to long does not change the bits, and nor does casting long to pointer for most (= all non w64) hosts. It is removed here. Macro or function tcg_qemu_tb_exec is used to set next_tb. The function also returns next_tb. Therefore tcg_qemu_tb_exec must return a tcg_target_ulong.

2012-03-16hw/pxa2xx.c: Fix handling of pxa2xx_i2c variable offset within regionPeter Maydell
The pxa2xx I2C controller can have its registers at an arbitrary offset within the MemoryRegion it creates. We use this to create two controllers, one which covers a region of size 0x10000 with registers starting at an offset 0x1600 into that region, and a second one which covers a region of size just 0x100 with the registers starting at the base of the region. The implementation of this offsetting uses two qdev properties, "offset" (which sets the offset which must be subtracted from the address to get the offset into the actual register bank) and "size", which is the size of the MemoryRegion. We were actually using "offset" for two purposes: firstly the required one of handling the registers not being at the base of the MemoryRegion, and secondly as a workaround for a deficiency of QEMU. Until commit 5312bd8b3, if a MemoryRegion was mapped at a non-page boundary, the address passed into the read and write functions would be the offset from the start of the page, not the offset from the start of the MemoryRegion. So when calculating the value to set the "offset" qdev property we included a rounding to a page boundary. Following commit 5312bd8b3 MemoryRegion read/write functions are now correctly passed the offset from the base of the region, and our workaround now means we're subtracting too much from addresses, resulting in warnings like "pxa2xx_i2c_read: Bad register 0xffffff90". The fix for this is simply to remove the rounding to a page boundary; this allows us to slightly simplify the expression since base - (base & (~region_size)) == base & region_size The qdev property "offset" itself must remain because it is still performing its primary job of handling register banks not being at the base of the MemoryRegion.

2012-03-16hw/pxa2xx_lcd.c: drop target_phys_addr_t usage in device stateMitsyanko Igor
Pxa2xx LCD controller is intended to work with 32-bit bus and it has no knowledge of system's physical address size, so it should not use target_phys_addr_t in it's state. Convert three variables in DMAChannel state from target_phys_addr_t to uint32_t, use VMSTATE_UINT32 instead of VMSTATE_UINTTL for these variables. We can do this safely because: 1) pxa2xx has 32-bit physical address; 2) rest of the code in file never assumes converted variables to have any size different from uint32_t; 3) we shouldn't have used VMSTATE_UINTTL in the first place because this macro is for target_ulong type (which can be different from target_phys_addr_t).

After commit 5312bd8b3152 we got memory region relative offsets into our mmio callbacks instead of page boundary based offsets.

2012-03-15pseries: Configure PCI bridge using propertiesDavid Gibson
Currently, the function spapr_create_phb() uses its parameters to initialize the correct memory windows for the new PCI Host Bridge (PHB). This is not the way things are supposed to be done with qdevs, and means you can't create extra PHBs easily using -device. Since pSeries machines can and do have many PHBs with various configurations, this is a real limitation, not just a theoretical. This patch, therefore, alters the PHB initialization code to use qdev properties to set these parameters of the new bridge, moving most of the code from spapr_create_phb() to spapr_phb_init(). While we're at it, we change the naming of each PCI bus and its associated memory regions to be less arbitrary and make it easier to relate the guest and qemu views of memory to each other.

2012-03-15kvm: Comparison with ioctl number macros needs to be unsignedDavid Gibson
In kvm-all.c we store an ioctl cmd number in the irqchip_inject_ioctl field of KVMState, which has type 'int'. This seems to make sense since the ioctl() man page says that the cmd parameter has type int. However, the kernel treats ioctl numbers as unsigned - sys_ioctl() takes an unsigned int, and the macros which generate ioctl numbers expand to unsigned expressions. Furthermore, some ioctls (IOC_READ ioctls on x86 and IOC_WRITE ioctls on powerpc) have bit 31 set, and so would be negative if interpreted as an int. This has the surprising and compile-breaking consequence that in kvm_irqchip_set_irq() where we do: return (s->irqchip_inject_ioctl == KVM_IRQ_LINE) ? 1 : event.status; We will get a "comparison is always false due to limited range of data type" warning from gcc if KVM_IRQ_LINE is one of the bit-31-set ioctls, which it is on powerpc. So, despite the fact that the man page and posix say ioctl numbers are signed, they're actually unsigned. The kernel uses unsigned, the glibc header uses unsigned long, and FreeBSD, NetBSD and OSX also use unsigned long ioctl numbers in the code. Therefore, this patch changes the variable to be unsigned, fixing the compile. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>

2012-03-15pseries: Add support for level interrupts to XICSDavid Gibson
The pseries "xics" interrupt controller, like most interrupt controllers can support both message (i.e. edge sensitive) interrupts and level sensitive interrupts, but it needs to know which are which. When I implemented the xics emulation for qemu, the only devices we supported were the PAPR virtual IO devices. These devices only use message interrupts, so they were the only ones I implemented in xics. Since then, however, we have added support for PCI devices, which use level sensitive interrupts. It turns out the message interrupt logic still actually works most of the time for these, but there are circumstances where we can lost interrupts due to the incorrect interrupt logic. This patch, therefore, implements the correct xics level-sensitive interrupt logic. The type of the interrupt is set when a device allocates a new xics interrupt.

2012-03-15pseries: Don't try to munmap() a malloc()ed TCE tableDavid Gibson
For the pseries machine, TCE (IOMMU) tables can either be directly malloc()ed in qemu or, when running on a KVM which supports it, mmap()ed from a KVM ioctl. The latter option is used when available, because it allows the (frequent bottlenext) H_PUT_TCE hypercall to be KVM accelerated. However, even when KVM is persent, TCE acceleration is not always possible. Only KVM HV supports this ioctl(), not KVM PR, or the kernel could run out of contiguous memory to allocate the new table. In this case we need to fall back on the malloc()ed table. When a device is removed, and we need to remove the TCE table, we need to either munmap() or free() the table as appropriate for how it was allocated. The code is supposed to do that, but we buggily fail to initialize the tcet->fd variable in the malloc() case, which is used as a flag to determine which is the right choice. This patch fixes the bug, and cleans up error messages relating to this path while we're at it.
