2023-10-25feat(fpu): add helper routines to read, write, compare FPU registersArunachalam Ganapathy
Add helper routines to read, write, write_rand and compare FPU state and FPU control/status registers. These helper routines can be called by testcases running in NS-EL2, R-EL1, S-EL1 payload. The caller has to pass memory to read/write FPU registers. Signed-off-by: Arunachalam Ganapathy <arunachalam.ganapathy@arm.com> Change-Id: I10ae5487c9f58e46434c1bd5b42fd458ec755045
2023-10-20Merge "test: exercise secure espi interrupt handling"Madhukar Pappireddy
2023-10-13test: exercise secure espi interrupt handlingRaghu Krishnamurthy
Hafnium/SPMC added support for enabling interrupts in the extended SPI range. With the help of an SiP SMC call that can pend an interrupt, this patch adds a test to trigger an espi interrupt when cactus is running and ensure it is handled. Additionally, a dummy device region node representing a fake peripheral has been added to the Cactus SP manifest. It is used to specify properties of the interrupt in the extended SPI range used for the above test scenario.

2023-04-14feat(interrupts): support for registering irq handlersMadhukar Pappireddy
This patch provides support for registering and unregistering handler that is invoked by Cactus SP while processing virtual irq interrupt. For this, we simply repurpose the existing framework that was used to perform tail end of interrupt handling. Also, this patch increases the count of virtual interrupts supported by Cactus SP inline with the corresponding change in Hafnium[1].

TFTF can send a hint to the destination SP to expect that the forwarded sleep command could be preempted by a non-secure interrupt.

2022-09-29feat(interrupts): resume interrupted target vCPUMadhukar Pappireddy
An SP could be interrupted by a NS interrupt whilst handling a direct message request from another SP. The target SP could send a managed exit response, if supported. Consequently, the sender of the direct message request resumes the target SP by allocating CPU cycles using dummy direct message request.

2022-09-29feat(interrupts): add support for handling managed exit through vIRQMadhukar Pappireddy
An SP could specify, through its partition manifest, that the preferred signaling mechanism for it to handle managed exit is vIRQ instead of the default choice (vFIQ). Hence, separate the vIRQ and vFIQ handlers and add support for identifying the source of the direct message request for the current endpoint to send the managed exit response.

2022-03-08fix(tftf): remove invalid_access test from standard testsManish Pandey
Invalid_access test suite performs negative tests by accessing invalid memory and catching it in custom exception handler. This test suite was made part of standard tests which is called for all platforms and each EL3 configuration. This test was failing for the case when EL3 was build with "HANDLE_EA_EL3_FIRST = 1" causing exceptions to be trapped in EL3 and not forwarded to EL2 to be handled by custom exception handler. To avoid this problem, remove this suite from standard test and introduce a new test configuration.

2022-03-01test(cactus): prevent realm region access from swdOlivier Deprez
This change adds TFTF and cactus tests to check a realm region cannot be accessed from secure world. A non-secure buffer is delegated to realm PAS and shared to a secure partition through FF-A memory sharing operations. The SP retrieves the region from the SPM, maps it and attempts a write access. The PE is expected to trigger a GPF data abort caught by a custom exception handler. Exception is trapped at S-EL1 within the secure partition because Hafnium configures HCR_EL2.GPF=0 (and SCR_EL3.GPF=0).

2021-10-04fix(cactus): memory sharing tests failure MPJ-Alves
The last test to share memory functionality tested the FFA_MEMORY_DONATE interface. After donating the memory, the original owner didn't update its stage-1 translation at EL1. Hence, when booting a MP setup, there would be a data abort, as at stage-2 translation the memory region is now owned by the receiver of the test. Share memory region was being allocated part of the BSS section, was being mapped as a static region in the xlat libraries. A static region is not meant to be unmapped. To fix the above points: - allocated a memory region in the partition manifest of all Cactus SPs for the sake of the memory sharing tests. - at stage-1 before using it for the first memory share operation, the sender would map its segment as a dynamic region. - if test included a FFA_MEMORY_DONATE call, after donation the owner unmaps the memory region from its stage-1 translation.
