3 | When we added SVE_MTEDESC_SHIFT, we effectively limited the | ||
4 | maximum size of MTEDESC. Adjust SIZEM1 to consume the remaining | ||
5 | bits (32 - 10 - 5 - 12 == 5). Assert that the data to be stored | ||
6 | fits within the field (expecting 8 * 4 - 1 == 31, exact fit). | ||

3 | unaligned accesses and which does not also set .impl.unaligned to | ||
4 | indicate that its read and write functions can do the unaligned | ||
5 | handling themselves. This is a problem, because at the moment the | ||
6 | core memory system does not implement the support for handling | ||
7 | unaligned accesses by doing a series of aligned accesses and | ||
8 | combining them (system/memory.c:access_with_adjusted_size() has a | ||
9 | TODO comment noting this). | ||
3 | 10 | ||
11 | Fortunately raven_io_read() and raven_io_write() will correctly deal | ||
12 | with the case of being passed an unaligned address, so we can fix the | ||
13 | missing unaligned access support by setting .impl.unaligned in the | ||
14 | MemoryRegionOps struct. | ||

1 | The MPS2 SCC device doesn't have any documentation of its properties; | 1 | Armv8.1+ CPUs have the Virtual Host Extension (VHE) which adds a |
---|---|---|---|
2 | add a "QEMU interface" format comment describing them. | 2 | non-secure EL2 virtual timer. We implemented the timer itself in the |
3 | CPU model, but never wired up its IRQ line to the GIC. | ||
4 | |||
5 | Wire up the IRQ line (this is always safe whether the CPU has the | ||
6 | interrupt or not, since it always creates the outbound IRQ line). | ||
7 | Report it to the guest via dtb and ACPI if the CPU has the feature. | ||
8 | |||
9 | The DTB binding is documented in the kernel's | ||
10 | Documentation/devicetree/bindings/timer/arm\,arch_timer.yaml | ||
11 | and the ACPI table entries are documented in the ACPI specification | ||
12 | version 6.3 or later. | ||
13 | |||
14 | Because the IRQ line ACPI binding is new in 6.3, we need to bump the | ||
15 | FADT table rev to show that we might be using 6.3 features. | ||
16 | |||
17 | Note that exposing this IRQ in the DTB will trigger a bug in EDK2 | ||
18 | versions prior to edk2-stable202311, for users who use the virt board | ||
19 | with 'virtualization=on' to enable EL2 emulation and are booting an | ||
20 | EDK2 guest BIOS, if that EDK2 has assertions enabled. The effect is | ||
21 | that EDK2 will assert on bootup: | ||
22 | |||
23 | ASSERT [ArmTimerDxe] /home/kraxel/projects/qemu/roms/edk2/ArmVirtPkg/Library/ArmVirtTimerFdtClientLib/ArmVirtTimerFdtClientLib.c(72): PropSize == 36 || PropSize == 48 | ||
24 | |||
25 | If you see that assertion you should do one of: | ||
26 | * update your EDK2 binaries to edk2-stable202311 or newer | ||
27 | * use the 'virt-8.2' versioned machine type | ||
28 | * not use 'virtualization=on' | ||
29 | |||
30 | (The versions shipped with QEMU itself have the fix.) | ||

1 | The patchset adding the GMAC ethernet to this SoC crossed in the | ||
2 | mail with the patchset cleaning up the NIC handling. When we | ||
3 | create the GMAC modules we must call qemu_configure_nic_device() | ||
4 | so that the user has the opportunity to use the -nic commandline | ||
5 | option to create a network backend and connect it to the GMACs. | ||
1 | 6 | ||
7 | Add the missing call. | ||

1 | Currently QEMU will warn if there is a NIC on the board that | ||
2 | is not connected to a backend. By default the '-nic user' will | ||
3 | get used for all NICs, but if you manually connect a specific | ||
4 | NIC to a specific backend, then the other NICs on the board | ||
5 | have no backend and will be warned about: | ||

15 | Make the WFI helper function return immediately in the usermode | 10 | We might call pmu_counter_enabled() on an M-profile CPU (for example |
16 | emulator. This turns WFI into a NOP, which is OK because: | 11 | from the migration pre/post hooks in machine.c); this should always |
17 | * architecturally "WFI is a NOP" is a permitted implementation | 12 | return false because these CPUs don't set ARM_FEATURE_PMU. |
18 | * aarch64 Linux kernels use the SCTLR_EL1.nTWI bit to trap | ||
19 | userspace WFI and NOP it (though aarch32 kernels currently | ||
20 | just let WFI do whatever it would do) | ||
21 | 13 | ||
22 | We could in theory make the translate.c code special case user-mode | 14 | Avoid the assertion by not calling arm_mdcr_el2_eff() before we |
23 | emulation and NOP the insn entirely rather than making the helper | 15 | have done the early return for "PMU not present". |
24 | do nothing, but because no real world code will be trying to | ||
25 | execute WFI we don't care about efficiency and the helper provides | ||
26 | a single place where we can make the change rather than having | ||
27 | to touch multiple places in translate.c and translate-a64.c. | ||
28 | 16 | ||
29 | Fixes: https://bugs.launchpad.net/qemu/+bug/1926759 | 17 | This fixes an assertion failure if you try to do a loadvm or |
18 | savevm for an M-profile board. | ||

1 | The unallocated_encoding() function is the same in both | 1 | From: Nabih Estefan <nabihestefan@google.com> |
---|---|---|---|
2 | translate-a64.c and translate.c; make the translate.c function global | ||
3 | and drop the translate-a64.c version. To do this we need to also | ||
4 | share gen_exception_insn(), which currently exists in two slightly | ||
5 | different versions for A32 and A64: merge those into a single | ||
6 | function that can work for both. | ||
7 | 2 | ||
8 | This will be useful for splitting up translate.c, which will require | 3 | Fix the nocm_gmac-test.c file to run on a nuvoton 7xx machine instead |
9 | unallocated_encoding() to no longer be file-local. It's also | 4 | of 8xx. Also fix comments referencing this and values expecting 8xx. |
10 | hopefully less confusing to have only one version of the function | ||
11 | rather than two. | ||

1 | 2 | ||
3 | An access fault is raised when the Access Flag is not set in the | ||
4 | looked-up PTE and the AFFD field is not set in the corresponding context | ||
5 | descriptor. This was already implemented for stage 2. Implement it for | ||
6 | stage 1 as well. | ||

5 | has the two arms of the ?: expression reversed. Fix the bug. | 6 | When we implemented this we picked which encoding to |
7 | use based on whether the CPU set ARM_FEATURE_AARCH64. | ||
8 | However this isn't right for three cases: | ||
9 | * the qemu-system-arm 'max' CPU, which is supposed to be | ||
10 | a variant on a Cortex-A57; it ought to use the same | ||
11 | encoding the A57 does and which the AArch64 'max' | ||
12 | exposes to AArch32 guest code | ||
13 | * the Cortex-R52, which is AArch32-only but has the CBAR | ||
14 | at the newer encoding (and where we incorrectly are | ||
15 | not yet setting ARM_FEATURE_CBAR_RO anyway) | ||
16 | * any possible future support for other v8 AArch32 | ||
17 | only CPUs, or for supporting "boot the CPU into | ||
18 | AArch32 mode" on our existing cores like the A57 etc | ||
6 | 19 | ||
7 | Fixes: b6ad6062f1e5 | 20 | Make the decision of the encoding be based on whether |
8 | Reported-by: Rebecca Cran <rebecca@nuviainc.com> | 21 | the CPU implements the ARM_FEATURE_V8 flag instead. |
22 | |||
23 | This changes the behaviour only for the qemu-system-arm | ||
24 | '-cpu max'. We don't expect anybody to be relying on the | ||
25 | old behaviour because: | ||
26 | * it's not what the real hardware Cortex-A57 does | ||
27 | (and that's what our ID register claims we are) | ||
28 | * we don't implement the memory-mapped GICv3 support | ||
29 | which is the only thing that exists at the peripheral | ||
30 | base address pointed to by the register | ||

1 | The VFPGenFixPointFn typedef is unused; delete it. | 1 | Architecturally, the AArch32 MSR/MRS to/from banked register |
---|---|---|---|
2 | instructions are UNPREDICTABLE for attempts to access a banked | ||
3 | register that the guest could access in a more direct way (e.g. | ||
4 | using this insn to access r8_fiq when already in FIQ mode). QEMU has | ||
5 | chosen to UNDEF on all of these. | ||
6 | |||
7 | However, for the case of accessing SPSR_hyp from hyp mode, it turns | ||
8 | out that real hardware permits this, with the same effect as if the | ||
9 | guest had directly written to SPSR. Further, there is some | ||
10 | guest code out there that assumes it can do this, because it | ||
11 | happens to work on hardware: an example Cortex-R52 startup code | ||
12 | fragment uses this, and it got copied into various other places, | ||
13 | including Zephyr. Zephyr was fixed to not use this: | ||
14 | https://github.com/zephyrproject-rtos/zephyr/issues/47330 | ||
15 | but other examples are still out there, like the selftest | ||
16 | binary for the MPS3-AN536. | ||
17 | |||
18 | For convenience of being able to run guest code, permit | ||
19 | this UNPREDICTABLE access instead of UNDEFing it. | ||

1 | On some boards, SCC config register CFG0 bit 0 controls whether | 1 | The MPS2 SCC device is broadly the same for all FPGA images, but has |
---|---|---|---|
2 | parts of the board memory map are remapped. Support this with: | 2 | minor differences in the behaviour of the CFG registers depending on |
3 | * a device property scc-cfg0 so the board can specify the | 3 | the image. In many cases we don't really care about the functionality |
4 | initial value of the CFG0 register | 4 | controlled by these registers and a reads-as-written or similar |
5 | * an outbound GPIO line which tracks bit 0 and which the board | 5 | behaviour is sufficient for the moment. |
6 | can wire up to provide the remapping | 6 | |
7 | For the AN536 the required behaviour is: | ||
8 | |||
9 | * A_CFG0 has CPU reset and halt bits | ||
10 | - implement as reads-as-written for the moment | ||
11 | * A_CFG1 has flash or ATCM address 0 remap handling | ||
12 | - QEMU doesn't model this; implement as reads-as-written | ||
13 | * A_CFG2 has QSPI select (like AN524) | ||
14 | - implemented (no behaviour, as with AN524) | ||
15 | * A_CFG3 is MCC_MSB_ADDR "additional MCC addressing bits" | ||
16 | - QEMU doesn't care about these, so use the existing | ||
17 | RAZ behaviour for convenience | ||
18 | * A_CFG4 is board rev (like all other images) | ||
19 | - no change needed | ||
20 | * A_CFG5 is ACLK frq in hz (like AN524) | ||
21 | - implemented as reads-as-written, as for other boards | ||
22 | * A_CFG6 is core 0 vector table base address | ||
23 | - implemented as reads-as-written for the moment | ||
24 | * A_CFG7 is core 1 vector table base address | ||
25 | - implemented as reads-as-written for the moment | ||
26 | |||
27 | Make the changes necessary for this; leave TODO comments where | ||
28 | appropriate to indicate where we might want to come back and | ||
29 | implement things like CPU reset. | ||
30 | |||
31 | The other aspects of the device specific to this FPGA image (like the | ||
32 | values of the board ID and similar registers) will be set via the | ||
33 | device's qdev properties. | ||

4 | 4 | "Subsystem for Embedded" SoC-equivalent that we model in hw/arm/armsse.c. | |
5 | The trans_* functions here are pure code motion with no changes. | 5 | It's therefore more convenient for us to model it as a completely |

7 | |||
8 | This commit adds the basic skeleton of the board model, and the | ||
9 | code to create all the RAM and ROM. We assume that we're probably | ||
10 | going to want to add more images in future, so use the same | ||

3 | 0x0000_0000, and the QSPI at 0x2800_0000. In the second map, they | ||
4 | are the other way around. | ||
5 | |||
6 | In hardware, the initial mapping can be selected by the user by | ||
7 | writing either "REMAP: BRAM" (the default) or "REMAP: QSPI" in the | ||
8 | board configuration file. The board config file is acted on by the | ||
9 | "Motherboard Configuration Controller", which is an entirely separate | ||
10 | microcontroller on the dev board but outside the FPGA. | ||
11 | |||
12 | The guest can also dynamically change the mapping via the SCC | ||
13 | CFG_REG0 register. | ||
14 | |||
15 | Implement this functionality for QEMU, using a machine property | ||
16 | "remap" with valid values "BRAM" and "QSPI" to allow the user to set | ||
17 | the initial mapping, in the same way they can on the FPGA, and | ||
18 | wiring up the bit from the SCC register to also switch the mapping. | ||
