2023-01-23target/arm: Unify checking for M Main Extension in MRS/MSRDavid Reiss
BASEPRI, FAULTMASK, and their _NS equivalents only exist on devices with the Main Extension. However, the MRS instruction did not check this, and the MSR instruction handled it inconsistently (warning BASEPRI, but silently ignoring writes to BASEPRI_NS). Unify this behavior and always warn when reading or writing any of these registers if the extension is not present.

We have two inclusion loops: block/block.h -> block/block-global-state.h -> block/block-common.h -> block/blockjob.h -> block/block.h block/block.h -> block/block-io.h -> block/block-common.h -> block/blockjob.h -> block/block.h I believe these go back to Emanuele's reorganization of the block API, merged a few months ago in commit d7e2fe4aac8. Fortunately, breaking them is merely a matter of deleting unnecessary includes from headers, and adding them back in places where they are now missing.

The new helper always validates the contents of FRM, even if the new rounding mode is not DYN. This is required by the vector unit. Track whether we've validated FRM separately from whether we've updated fp_status with a given rounding mode, so that we can elide calls correctly. This partially reverts d6c4d3f2a69 which attempted the to do the same thing, but with two calls to gen_set_rm(), which is both inefficient and tickles an assertion in decode_save_opc.

2023-01-20target/riscv: Fix up masking of vsip/vsie accessesAndrew Bresticker
The current logic attempts to shift the VS-level bits into their correct position in mip while leaving the remaining bits in-tact. This is both pointless and likely incorrect since one would expect that any new, future VS-level interrupts will get their own position in mip rather than sharing with their (H)S-level equivalent. Fix this, and make the logic more readable, by just making off the VS-level bits and shifting them into position. This also fixes reads of vsip, which would only ever report vsip.VSSIP since the non-writable bits got masked off as well.

2023-01-20target/riscv/cpu.c: do not skip misa logic in riscv_cpu_realize()Daniel Henrique Barboza
All RISCV CPUs are setting cpu->cfg during their cpu_init() functions, meaning that there's no reason to skip all the misa validation and setup if misa_ext was set beforehand - especially since we're setting an updated value in set_misa() in the end. Put this code chunk into a new riscv_cpu_validate_set_extensions() helper and always execute it regardless of what the board set in env->misa_ext. This will put more responsibility in how each board is going to init their attributes and extensions if they're not using the defaults. It'll also allow realize() to do its job looking only at the extensions enabled per se, not corner cases that some CPUs might have, and we won't have to change multiple code paths to fix or change how extensions work.

2023-01-20target/riscv/cpu: set cpu->cfg in register_cpu_props()Daniel Henrique Barboza
There is an informal contract between the cpu_init() functions and riscv_cpu_realize(): if cpu->env.misa_ext is zero, assume that the default settings were loaded via register_cpu_props() and do validations to set env.misa_ext. If it's not zero, skip this whole process and assume that the board somehow did everything. At this moment, all SiFive CPUs are setting a non-zero misa_ext during their cpu_init() and skipping a good chunk of riscv_cpu_realize(). This causes problems when the code being skipped in riscv_cpu_realize() contains fixes or assumptions that affects all CPUs, meaning that SiFive CPUs are missing out. To allow this code to not be skipped anymore, all the cpu->cfg.ext_* attributes needs to be set during cpu_init() time. At this moment this is being done in register_cpu_props(). The SiFive boards are setting their own extensions during cpu_init() though, meaning that they don't want all the defaults from register_cpu_props(). Let's move the contract between *_cpu_init() and riscv_cpu_realize() to register_cpu_props(). Inside this function we'll check if cpu->env.misa_ext was set and, if that's the case, set all relevant cpu->cfg.ext_* attributes, and only that. Leave the 'misa_ext' = 0 case as is today, i.e. loading all the defaults from riscv_cpu_extensions[]. register_cpu_props() can then be called by all the cpu_init() functions, including the SiFive ones. This will make all CPUs behave more in line with what riscv_cpu_realize() expects. This will also make the cpu_init() functions even more alike, but at this moment we would need some design changes in how we're initializing extensions/attributes (e.g. some CPUs are setting cfg options after register_cpu_props(), so we can't simply add the function to a common post_init() hook) to make a common cpu_init() code across all CPUs.

The 'hwaddr' type is defined in "exec/hwaddr.h" as: hwaddr is the type of a physical address (its size can be different from 'target_ulong'). All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx: $ fgrep define include/exec/hwaddr.h #define HWADDR_H #define HWADDR_BITS 64 #define HWADDR_MAX UINT64_MAX #define TARGET_FMT_plx "%016" PRIx64 ^^^^^^ #define HWADDR_PRId PRId64 #define HWADDR_PRIi PRIi64 #define HWADDR_PRIo PRIo64 #define HWADDR_PRIu PRIu64 #define HWADDR_PRIx PRIx64 #define HWADDR_PRIX PRIX64 Since hwaddr's size can be *different* from target_ulong, it is very confusing to read one of its format using the 'TARGET_FMT_' prefix, normally used for the target_long / target_ulong types: $ fgrep TARGET_FMT_ include/exec/cpu-defs.h #define TARGET_FMT_lx "%08x" #define TARGET_FMT_ld "%d" #define TARGET_FMT_lu "%u" #define TARGET_FMT_lx "%016" PRIx64 #define TARGET_FMT_ld "%" PRId64 #define TARGET_FMT_lu "%" PRIu64 Apparently this format was missed during commit a8170e5e97 ("Rename target_phys_addr_t to hwaddr"), so complete it by doing a bulk-rename with: $ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-Id: <20230110212947.34557-1-philmd@linaro.org> [thuth: Fix some warnings from checkpatch.pl along the way] Signed-off-by: Thomas Huth <thuth@redhat.com>

2023-01-13target/arm: allow writes to SCR_EL3.HXEn bit when FEAT_HCX is enabledEvgeny Iakovlev
ARM trusted firmware, when built with FEAT_HCX support, sets SCR_EL3.HXEn bit to allow EL2 to modify HCRX_EL2 register without trapping it in EL3. Qemu uses a valid mask to clear unsupported SCR_EL3 bits when emulating SCR_EL3 write, and that mask doesn't include SCR_EL3.HXEn bit even if FEAT_HCX is enabled and exposed to the guest. As a result EL3 writes of that bit are ignored.

2023-01-11i386: Emit correct error code for 64-bit IDT entryJoe Richey
When in 64-bit mode, IDT entiries are 16 bytes, so `intno * 16` is used for base/limit/offset calculations. However, even in 64-bit mode, the exception error code still uses bits [3,16) for the invlaid interrupt index. This means the error code should still be `intno * 8 + 2` even in 64-bit mode.

2023-01-06RISC-V: Add Zawrs ISA extension supportChristoph Muellner
This patch adds support for the Zawrs ISA extension. Given the current (incomplete) implementation of reservation sets there seems to be no way to provide a full emulation of the WRS instruction (wake on reservation set invalidation or timeout or interrupt). Therefore, we just exit the TB and return to the main loop. The specification can be found here: https://github.com/riscv/riscv-zawrs/blob/main/zawrs.adoc Note, that the Zawrs extension is frozen, but not ratified yet. Changes since v3: * Remove "RFC" since the extension is frozen * Rebase on master and fix integration issues * Fix entry ordering in extension list Changes since v2: * Rebase on master and resolve conflicts * Adjustments according to a specification change * Inline REQUIRE_ZAWRS() since it has only one user Changes since v1: * Adding zawrs to the ISA string that is passed to the kernel Signed-off-by: Christoph Müllner <christoph.muellner@vrull.eu> Reviewed-by: Alistair Francis <alistair.francis@wdc.com> Message-Id: <20221005144948.3421504-1-christoph.muellner@vrull.eu> Signed-off-by: Alistair Francis <alistair.francis@wdc.com>

2023-01-06target/riscv: Fix mret exception cause when no pmp rule is configuredBin Meng
The priv spec v1.12 says: If no PMP entry matches an M-mode access, the access succeeds. If no PMP entry matches an S-mode or U-mode access, but at least one PMP entry is implemented, the access fails. Failed accesses generate an instruction, load, or store access-fault exception. At present the exception cause is set to 'illegal instruction' but should have been 'instruction access fault'.

sstatus register dump is currently missing in riscv_cpu_dump_state(). As sstatus is a copy of mstatus, which is described in the priv spec, it seems redundant to print the same information twice.
