I don’t think this has been adequately tested yet. The methods of clearing interrupts arent’ right. See Figure 89 about interrupt sources. For example, Line 115 and 116 are not right. Csrc sip, 32 only works if sip is implemented, which requires the S extension, which is not present in a processor with only machine mode. Csrc mip, 32 clears STIP, not mtimer. MEIP and SEIP are also dependent on the PLIC. WALLY-init-lib needs to clear both of these interrupt sources at the PLIC. |
