2014-02-26target-arm: Store AIF bits in env->pstate for AArch32Peter Maydell1-2/+2
To avoid complication in code that otherwise would not need to care about whether EL1 is AArch32 or AArch64, we should store the interrupt mask bits (CPSR.AIF in AArch32 and PSTATE.DAIF in AArch64) in one place consistently regardless of EL1's mode. Since AArch64 has an extra enable bit (D for debug exceptions) which isn't visible in AArch32, this means we need to keep the enables in env->pstate. (This is also consistent with the general approach we're taking that we handle 32 bit CPUs as being like AArch64/ARMv8 CPUs but which only run in 32 bit mode.)

Implement the AArch64 TTBR* registers. For v7 these were already 64 bits to handle LPAE, but implemented as two separate uint32_t fields. Combine them into a single uint64_t which can be used for all purposes. Since this requires touching every use, take the opportunity to rename the field to the architectural name.

The ethernet device in the musicpal only has two tx queues, but we modelled it with four CTDP registers, presumably a cut and paste from the rx queue registers. Since the tx_queue[] array is only 2 entries long this allowed a guest to overrun this buffer. Remove the nonexistent registers.

2014-01-08arm/xilinx_zynq: Always instantiate the GEMsPeter Crosthwaite1-11/+6
Don't conditionalise GEM instantiation on networking attachments. The device should always be present even if not attached to a network. This allows for probing of the device by expectant guests (such as OS's). This is needed because sysbus (or AXI in Xilinx's real hw case) is not self identifying so the guest has no dynamic way of detecting device absence. Also allows for testing of the GEM in loopback mode with -net none.

QEMU uses the reversed mapping and does not map 'space' to two different matrix positions. Some other keys are either missing or might be mapped wrongly (cf. Linux kernel code).

2013-12-23sysbus: Set cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+0
device_add plugs devices into suitable bus. For "real" buses, that actually connects the device. For sysbus, the connections need to be made separately, and device_add can't do that. The device would be left unconnected, and could not possibly work. Quite a few, but not all sysbus devices already set cannot_instantiate_with_device_add_yet in their class init function. Set it in their abstract base's class init function sysbus_device_class_init(), and remove the now redundant assignments from device class init functions.

2013-12-23qdev: Replace no_user by cannot_instantiate_with_device_add_yetMarkus Armbruster1-1/+1
In an ideal world, machines can be built by wiring devices together with configuration, not code. Unfortunately, that's not the world we live in right now. We still have quite a few devices that need to be wired up by code. If you try to device_add such a device, it'll fail in sometimes mysterious ways. If you're lucky, you get an unmysterious immediate crash. To protect users from such badness, DeviceClass member no_user used to make device models unavailable with -device / device_add, but that regressed in commit 18b6dad. The device model is still omitted from help, but is available anyway. Attempts to fix the regression have been rejected with the argument that the purpose of no_user isn't clear, and it's prone to misuse. This commit clarifies no_user's purpose. Anthony suggested to rename it cannot_instantiate_with_device_add_yet_due_to_internal_bugs, which I shorten somewhat to keep checkpatch happy. While there, make it bool. Every use of cannot_instantiate_with_device_add_yet gets a FIXME comment asking for rationale. The next few commits will clean them all up, either by providing a rationale, or by getting rid of the use. With that done, the regression fix is hopefully acceptable.

For AArch64 we will obviously require a different set of primary and secondary boot loader code fragments. However currently we hardcode the offsets into the loader code where we must write the entrypoint and other data into arm_load_kernel().

2013-12-17Fix NOR flash device ID readingRoy Franz1-3/+3
Fix NOR flash manufacturer and device ID reading. This now properly takes into account device widths and device max widths as required. The reading of these IDs uses the same max_width dependent addressing as CFI queries. The old code remains for chips that don't specify a device width, as the new code relies on a device width being set in order to properly operate. The existing code seems very broken. Only ident0 and ident1 are used in the new code, as other fields relate to the lock state of blocks in flash. The VExpress flash configuration has been updated to match the new code, as the existing definition was 'wrong' in order to return the expected results with the broken device ID code.

2013-12-10hw/arm: Add 'virt' platformPeter Maydell2-1/+445
Add 'virt' platform support corresponding to arch/arm/mach-virt in the Linux kernel tree. This has no platform-specific code but can use any device whose kernel driver is is able to work purely from a device tree node. We use this to instantiate a minimal set of devices: a GIC and some virtio-mmio transports.
