WebThis is currently usable with 2 clocksources: the CP0 count register, which is accessible to user-mode via RDHWR on R2 and later cores, or the MIPS Global Interrupt Controller (GIC) timer, which provides a "user-mode visible" section containing a mirror of its counter registers. This section must be mapped into user memory, which is done below ... WebThat error looks strange, are you sure that the assembler gets picked up from the cross-compile toolchain ?

The Lexra LX5280 CPU [1] [2] implements the MIPS-I ISA, without unaligned load/store instructions (lwl, lwr, swl, swr). The programming model of this CPU is very similar. to the R3000 programming model, with a few differences. The Realtek RTL8186 SoC has this CPU, so this patch is required. for future RTL8186 SoC support. onyx cave cave city https://ethicalfork.com
