2023-03-06riscv: semihosting: replace inline assembly with assembly fileAndre Przywara
So far we used inline assembly to inject the actual instruction that triggers the semihosting service. While this sounds elegant, as it's really only about a few instructions, it has some serious downsides: - We need some barriers in place to force the compiler to issue writes to a data structure before issuing the trap instruction. - We need to convince the compiler to actually fill the structures that we use pointers to. - We need a memory clobber to avoid the compiler caching the data in those structures, when semihosting writes data back. - We need register arguments to make sure the function ID and the pointer land in the right registers. This is all doable, but fragile and somewhat cumbersome. Since we now have a separate function in an extra file anyway, we can do away with all the magic and just write that in an actual assembler. This is much more readable and robust. Signed-off-by: Andre Przywara <andre.przywara@arm.com> Reviewed-by: Sean Anderson <sean.anderson@seco.com>

2023-03-06powerpc, mpc83xx: Remove CONFIG_ELBC_BRx_ORxChristophe Leroy
Commit fe7d654d04 ("mpc83xx: Migrate CONFIG_SYS_{BR, OR}*_PRELIM to Kconfig") converted CONFIG_SYS_{BRx/ORx}_PRELIM to Kconfig by implementing a fine-grained selection of every bit in Kconfig. But commit c7fad78ec0 ("Convert CONFIG_SYS_BR0_PRELIM et al to Kconfig") reworked it so that you now just have to provide the raw value of each register in Kconfig. However, all fine-grained Kconfig items remained allthough they are not used anymore. Remove them all.

2023-03-06arm64: Reduce PT size estimation complexityMarc Zyngier
count_required_pts()'s complexity is high if mappings are not using the largest possible block size (due to some other requirement such as tracking dirty pages, for example). Let's switch to a method that follows the pattern established with the add_map() helper, and make it almost instantaneous instead of taking a large amount of time if 2MB mappings are in use instead of 1GB.

2023-03-06arm64: Reduce add_map() complexityMarc Zyngier
In the add_map() function, for each level it populates, it iterates from the root of the PT tree, making it ineficient if a mapping needs to occur past level 1. Instead, replace it with a recursive (and much simpler) algorithm that keeps the complexity as low as possible. With this, mapping 512GB at level 2 goes from several seconds down to not measurable on an A55 machine. We keep the block mappings at level 1 for now though.

2023-03-06arm64: Initialize TLB memory if CMO_BY_VA_ONLYPierre-Clément Tosi
Memory used to hold the page tables is allocated from the top of RAM with no prior initialization and could therefore hold invalid data. As invalidate_dcache_all() will be called before the MMU has been initialized and as that function relies indirectly on the page tables when using CMO_BY_VA_ONLY, these must be in a valid state from their allocation.

2023-03-06arm: cpu: Add optional CMOs by VAMarc Zyngier
Exposing set/way cache maintenance to a virtual machine is unsafe, not least because the instructions are not permission-checked but also because they are not broadcast between CPUs. Consequently, KVM traps and emulates such maintenance in the host kernel using by-VA operations and looping over the stage-2 page-tables. However, when running under protected KVM, these instructions are not able to be emulated and will instead result in an exception being delivered to the guest. Introduce CONFIG_CMO_BY_VA_ONLY so that virtual platforms can select this option and perform by-VA cache maintenance instead of using the set/way instructions.
