2020-10-21Update htif.cc (#577)S.Pawan Kumar1-1/+1
Bug fix for final byte in signature output.
2020-10-15reduce sig_len constraint to 4 bytes (#569)Neel Gala2-6/+20
* reduce sig_len constraint to 4 bytes Spike currently asserts that the signature length should always be a multiple of 16-bytes. However, the compliance suite has agreed to upon the signature being a multiple ot 4-bytes. This prevents some of the tests to run on spike since it fails the assertion. The proposed change fixes this issue and reduces the assertion to 4 bytes. * Added size argument to htif arguments and zero padding for signature output. Defaultline size-16. * Modified type of line_size to unsigned. * Renamed size to granularity. * Rename granularity to signature-granularity. Co-authored-by: dracarys99 <spawan1999@gmail.com>
2020-10-10Fix new ELF checks on big endian hosts (#567)Marcus Comstedt1-4/+6
The new macros IS_ELF_... introduced in 80b5b2f5 were not endian safe.

Support loading multiple ELF files via a new payload HTIF option
2020-01-31Support loading multiple ELF files via a new payload HTIF optionJames Clarke2-7/+31
Firmware implementations, such as OpenSBI's fw_jump, make use of this feature on other targets to avoid having to be rebuilt every time the payload is updated.

2020-01-25Refuse to load non-EXEC/non-RISC-V/non-V1 ELFs (#388)Alexander Lent2-0/+10
Stricter validation of ELF binaries improves usability with informative assertions. This prevents users from loading ELF relocatable files and binaries compiled for their (non-RISC-V) workstations, for example. Without this patch, spike would attempt to load nearly any ELF given, but it would usually fail with an error about debug module accesses, since the given ELF causes accesses in the debug module's memory space. Even if spike successfully loaded the ELF file, it would still misbehave during simulation, for example in the case of ELF relocatable files. ELF magic numbers come from official ELF documents: TIS ELF spec v1.2, via Linux Foundation Referenced Specifications See: https://refspecs.linuxbase.org/ RISC-V magic number comes from official RISC-V ELF documents: See: riscv/riscv-elf-psabi-doc@60c25981b62c0b43d16142f8a12c8b1e98e60d4d
