Asahi Lina	c746549c2e	hv: Map RAM via tracer infra, handle carveouts in Python Previously RAM was mapped ad-hoc, but this can end up interacting poorly with the tracer infrastructure which we are now using for RAM too. Move to mapping guest RAM via the tracer infra, and also unmap the TZ carveouts in the Python side so it knows about them. This is a HV ABI break.

Kyle Evans	0ba2027e5e	proxyclient: tools: add a FreeBSD loader The differences are documented in the script itself, but the main odd bit is that we pass the provided kernel as an initramfs. Our modified loader will probe for the initramfs start/end props in FDT and put up a memdisk that we load the kernel from. This choice was made for two reasons: 1.) Avoid ad-hoc interpretations of a memory region in m1n1, it doesn't care if we actually passed it an initramfs or not anyways. 2.) We already had some code on hand to do this in our loader, so I suspect we've done similar shenanigans elsewhere anyways. This also requires a U-Boot change to allow bootefi of an arbitrary location, as long the size is provided. The alignment constraints for loader/kernel were kept arbitrarily. The kernel will be bounced anyways by loader. I don't recall what alignment requirements UEFI payloads have, but 2M seems reasonable.

Kyle Evans	3b68165900	proxyclient: tools: fix linux U-Boot support -t is optional, we may not have a tty_dev, so we can avoid trying to grab the baudrate from it if it's unspecified. We don't want to use dtb_addr for booti; this is the unmodified payload. m1n1 will load it and add bits to it at a separate address for passing on to U-Boot. For booti purposes, we actually want the augmented FDT rather than the user-specified. Signed-off-by: Kyle Evans <kevans@FreeBSD.org>	2022-04-16 19:18:06 +09:00

Vincent Duvert	1a95a9fc17	Shell: do not access properties on startup Change the way the shell finds methods to add to the locals on startup: the methods are queried on the object’s class, rather than the object itself. This allows detecting if an object’s member is a property and ignore it, rather than accessing the property. Attributes whose name starts by ‘_’ are also now ignored, which avoids importing private methods or Python magic methods in the shell namespace. Fixes spurious accesses to ProxyUtils’s SIMD properties (b, h, etc) on shell startup, which caused a ProxyCommandError if m1n1 is not recent enough.

Janne Grunau	d61bf13cb0	hv: shadow perf monitor IRQ mode and state The development Mac OS kernel panics if the PMCR0 sysreg is in an unexpected state. To avoid that the hypervisor needs to shadow the interrupt mode and interrupt active flag after it mask the PM FIQ. Mac OS reads and writes frequently from PMCR0 and PMC 0/1 so handling in m1n1 is preferred over Python. Signed-off-by: Janne Grunau <j@jannau.net>	2021-06-09 19:47:20 +09:00

The feature is enabled if m1n1 supports it; checksumming is kept enabled for UART communication. * To ensure no packet loss when checksumming is disabled, an extra sentinel value is added after the exchanged data for memory read/write operations.

Hector Martin	b8349819fe	Implement calling code as EL1 This works by clearing HCR_EL2.TGE, and then doing essentially the same thunk/return dance as for EL0 calls. However, since most EL1 exceptions are not routed to EL2, we install hypercall vectors in EL1 to forward them to EL2, and then short circuit the exception return to whatever triggered the original exception.
