extension specification inconsistencies - Update long_name in Zaamo.yaml to match atomic instruction description - Correct instruction name from amoadd.w to amoadd.d in amoadd.d.yaml - Remove duplicate NOTE sections in Zaamo.yaml documentation These changes align the Zaamo extension specification with proper atomic memory operation naming conventions and eliminate redundant documentation

17 00:00:00 2001 From: Abhijit Das Date: Mon, 11 Aug 2025 19:18:52 +0000 Subject: [PATCH 34/50] feat: reorganize AMO instructions by size between Zaamo and Zabha extensions - Move byte (b) and halfword (h) AMO instructions from Zaamo to Zabha - Update layout templates with conditional definedBy logic for proper extension assignment - Update Rakefile to generate instruction files to correct directories based on size - Zaamo now contains only word (w) and doubleword (d) AMO instructions - Zabha now contains byte (b) and halfword (h) AMO instructions - Maintain backward compatibility while organizing by instruction size as per RISC-V specification Signed-off-by: GitHub --- Rakefile | 32 ++++- .../isa/inst/Zaamo/amoadd.SIZE.AQRL.layout | 2 +- spec/std/isa/inst/Zaamo/amoadd.b.yaml | 135

layout conditionals - Fixed MISA condition logic across all AMO files and layout templates - Corrected redundant parenthetical text in .aqrl files - Simplified layout template conditionals for b,h,w size handling - All 9 layout templates now have consistent logic and formatting - Applied fixes across both Zaamo and Zabha extensions Addresses feedback from @ThinkOpenly and @dhower-qc in PR #921

Sat, 16 Aug 2025 09:55:30 +0000 Subject: [PATCH 38/50] fix: resolve AMO opcode overlaps by fixing base files to use aq=0,rl=0 - Fix base AMO files to use fixed aq=0,rl=0 instead of variables - Update operation calls to use 1'b0,1'b0 instead of aq,rl variables - Add amocas layout template for Zabha (b,h) variants - Generate amocas memory ordering variants (.aq, .rl, .aqrl) - Fix YAML headers in generated amocas files - This resolves the opcode overlap issue mentioned by mentor Signed-off-by: GitHub --- Rakefile | 98 ++++++++++ spec/std/isa/inst/Zaamo/amoadd.d.yaml | 8 +-

atomically loads 64-bits of a data value from address in +xs1, compares the loaded value to a 64-bit value held in a register pair +consisting of xd and xd+1, and if the comparison is bitwise equal, then +stores the 64-bit value held in the register pair xs2 and xs2+1 to the +original address in xs1. The value loaded from memory is placed into the +register pair xd and xd+1. The instruction requires the first register in +the pair to be even numbered; encodings with odd-numbered registers +specified in xs2 and xd are reserved. When the first register of a source +register pair is x0, then both halves of the pair read as zero. When the +first register of a destination register pair is x0, then the entire +register result is discarded and neither destination register is written. + +For RV64, AMOCAS.D atomically loads 64-bits of a data value from address in +xs1, compares the loaded value to a 64-bit value held in xd, and if the +comparison is bitwise equal, then stores the 64-bit value held in xs2 to the +original address in xs1. The value loaded from memory is placed into +register xd. + +Just as for AMOs in the A extension, AMOCAS.D requires that the address held +in xs1 be naturally aligned to the size of the operand (i.e., eight-byte +aligned for doublewords). And the same exception options apply if the +address is not naturally aligned. + +Just as for AMOs in the A extension, the AMOCAS.D optionally provides release +consistency semantics, using the aq and rl bits, to help implement +multiprocessor synchronization. The memory operation performed by an +AMOCAS.D, when successful, has acquire semantics if aq bit is 1 and has +release semantics if rl bit is 1. The memory operation performed by an +AMOCAS.W/D/Q, when not successful, has acquire semantics if aq bit is 1 but +does not have release semantics, regardless of rl. + +A FENCE instruction may be used to order the memory read access and, if +produced, the memory write access by an AMOCAS.D instruction. + +[Note] An unsuccessful AMOCAS.D may either not perform a memory write or may +write back the old value loaded from memory.

charset=UTF-8 Content-Transfer-Encoding: 8bit This commit refactors the Rakefile build system and fixes AMO instruction layout templates to eliminate code duplication and enable proper dependency-driven generation: **Rakefile Changes:** - Replace manual AMO file generation with dependency-driven system - Remove ~50 lines of duplicate manual task invocations - Add AMO instruction file dependencies to test:inst_encodings task - Generate 152 AMO files automatically through proper dependencies **Layout Template Fixes:** - spec/std/isa/inst/Zaamo/amomaxu.SIZE.AQRL.layout: Remove duplicate content - spec/std/isa/inst/Zabha/amocas.SIZE.AQRL.layout: Fix templated function call syntax (amocas<<%= ... %>> → amocas<%= ... %>) **Benefits:** - Eliminates mentor-flagged code duplication in Rakefile - Enables automatic AMO instruction file generation through dependencies - Fixes template syntax errors preventing proper file generation - Maintains full functionality while improving maintainability The dependency system ensures AMO instruction files are generated automatically when needed, removing the need for manual task invocations while preserving all existing functionality.
