2024-06-12Fix a few compile warningsAndrew Waterman1-16/+16
2023-12-08Use brace initializers for debug_module_config_t defaultsJerry Zhao1-9/+9
2023-12-01Add SBA write delay.Tim Newsome1-2/+3
This is helpful to test OpenOCD behavior when sbbusyerror is set.

2023-07-05Let debugger control hart availabilityTim Newsome1-0/+6
This change lets me test OpenOCD's behavior when harts become available. It only affects how things look to the debugger. Harts that are "unavailable" still execute code as usual. Control is implemented through the 2 LSBs of the DMCUSTOM register in the Debug Module.
2023-06-20debug: Remove debug_module_t::add_device, its redundantJerry Zhao1-2/+0
2023-03-09Switch debug_module to use simif_t instead of sim_tScott Johnson1-3/+3
In keeping with the spirit of simif_t.
2023-02-27Make debug module tolerant of discontiguous hart IDsAndrew Waterman1-6/+3
The general strategy is to avoid iterating over the ID space.
2022-12-16Remove debug_module.h -> mmu.h dependencyJerry Zhao1-1/+2
2022-10-07Add --dm-no-abstract-fpr option.Tim Newsome1-0/+1
Previously FPRs could always be accessed using abstract commands. I need this to get coverage of some OpenOCD code that I broke. (See https://github.com/riscv/riscv-openocd/pull/745)
2022-08-10Fix code indentation in processor.cc, interactive.cc, debug_module.h/ccWeiwei Li1-16/+16
execute.cc, entropy_source.h and v_ext_macros.h
2022-01-06Don't say "master" (#898)Tim Newsome1-1/+1
Requested by "LfX Security - Non Inclusive Language Alerts"
2021-02-04Refactor headersAndrew Waterman1-1/+3
2020-08-11Add option to dissable implicit ebreak in program bufferSamuel Obuch1-0/+1
2019-07-16Writing non-existent CSRs, access FPRs with mstatus.FS=0 (#311)Tim Newsome1-1/+1
* Don't corrupt s0 when abstract CSR write fails. * Support abstract FPR access then mstatus.FS=0 Discussion on the spec list leans towards this being a requirement. Certainly users want their debugger to be able to access all registers regardless of target state.
2019-05-14Clean up debug module options. (#299)Tim Newsome1-12/+14
* Clean up debug module options. 1. Instead of passing each one a few levels deep, create debug_module_config_t which contains them all. 2. Rename all those command line options so they start with --dm for debug module. 3. Add --dm-no-halt-groups to disable halt group support. * Update changelog.
2019-04-04Add --debug-no-abstract-csr (#267)Tim Newsome1-1/+3
This is used to make sure that OpenOCD can work on targets that don't support abstract access to CSR registers. It replaces a simpler hack, which caused #266.
2019-04-02Implement debug hasel support (#287)Tim Newsome1-2/+7
* Implement hasel/hawindow support. This should allow simultaneous resume and halt to work. * Fix anyrunning/anyhalted bits. * Add --without-hasel argument for testing. * Make halt/resume times more equal. Switching threads after every instruction executed in debug mode leads to a lot of extra instructions being executed on the "other" thread when both are really supposed to halt/resume near-simultaneously. Fixed that by adding wfi to debug_rom.S, and implementing it to switch to the other hart as well as check for JTAG input. When resuming, write the hart ID to the debug ROM so that the DM knows which hart actually resumed. (Before simultaneous resume it just assumed the current one.) Also got rid of resume symbol in debug_rom.S since it had no purpose. * Preserve Debug ROM entry points. * Make sure minstret is correct when wfi happens.
2019-03-04Implement halt groups (#280)Tim Newsome1-4/+10
* Update debug_defines from latest spec. * Implement halt groups. This lets the debugger halt multiple harts near simultaneously. * Revert encoding, which I updated accidentally.
2018-12-13Add --dmi-rti and --abstract-rti to test OpenOCD.Tim Newsome1-2/+13
Optionally make spike behave more like real hardware, to automatically test OpenOCD's handling of such hardware.
2018-08-23Add dummy custom debug registers, to test OpenOCD. (#233)Tim Newsome1-0/+3
2018-06-11Update debug_defines.hTim Newsome1-0/+2
Add support for hartselhi parsing, but other parts of the debug code still don't support more than 1024 harts.
2018-03-16Implement debug havereset bitsTim Newsome1-1/+7
2018-03-07Merge pull request #177 from riscv/debug_authTim Newsome1-2/+13
Add debug module authentication.
2018-02-27Add debug module authentication.Tim Newsome1-2/+13
Off by default, enabled with --debug-auth. The protocol is very simple (definitely not secure) to allow debuggers to test their authentication feature. To authenticate a debugger must: 1. Read authdata 2. Write to authdata the value that it just read, plus 1
2018-02-19WIP. Doesn't work.Tim Newsome1-1/+1
2018-02-01Add --debug-sba optionTim Newsome1-1/+2
This lets the user control whether the system bus access implements bus mastering.

2017-12-11Update to latest debug_defines.h.Tim Newsome1-5/+4
2017-12-11Make progbuf a run-time option.Tim Newsome1-6/+12
Also add an implicit ebreak after the program buffer. This is not part of the spec, but hopefully it will be.

2016-05-23Turn off debugging.Tim Newsome1-4/+0
All the printfs would be pretty annoying if you're actually using this to debug something. Also fixed a small jump bug in halt.
