| 648 | /* | ||
| 649 | * General notes on MMU parameters. | ||
| 650 | * | ||
| 651 | * Terminology: | ||
| 652 | * ASID = address-space ID (acts as an "extension" of virtual addresses) | ||
| 653 | * VPN = virtual page number | ||
| 654 | * PPN = physical page number | ||
| 655 | * CA = encoded cache attribute (access modes) | ||
| 656 | * TLB = translation look-aside buffer (term is stretched somewhat here) | ||
| 657 | * I = instruction (fetch accesses) | ||
| 658 | * D = data (load and store accesses) | ||
| 659 | * way = each TLB (ITLB and DTLB) consists of a number of "ways" | ||
| 660 | * that simultaneously match the virtual address of an access; | ||
| 661 | * a TLB successfully translates a virtual address if exactly | ||
| 662 | * one way matches the vaddr; if none match, it is a miss; | ||
| 663 | * if multiple match, one gets a "multihit" exception; | ||
| 664 | * each way can be independently configured in terms of number of | ||
| 665 | * entries, page sizes, which fields are writable or constant, etc. | ||
| 666 | * set = group of contiguous ways with exactly identical parameters | ||
| 667 | * ARF = auto-refill; hardware services a 1st-level miss by loading a PTE | ||
| 668 | * from the page table and storing it in one of the auto-refill ways; | ||
| 669 | * if this PTE load also misses, a miss exception is posted for s/w. | ||
| 670 | * min-wired = a "min-wired" way can be used to map a single (minimum-sized) | ||
| 671 | * page arbitrarily under program control; it has a single entry, | ||
| 672 | * is non-auto-refill (some other way(s) must be auto-refill), | ||
| 673 | * all its fields (VPN, PPN, ASID, CA) are all writable, and it | ||
| 674 | * supports the XCHAL_MMU_MIN_PTE_PAGE_SIZE page size (a current | ||
| 675 | * restriction is that this be the only page size it supports). | ||
| 676 | * | ||
| 677 | * TLB way entries are virtually indexed. | ||
| 678 | * TLB ways that support multiple page sizes: | ||
| 679 | * - must have all writable VPN and PPN fields; | ||
| 680 | * - can only use one page size at any given time (eg. setup at startup), | ||
| 681 | * selected by the respective ITLBCFG or DTLBCFG special register, | ||
| 682 | * whose bits n*4+3 .. n*4 index the list of page sizes for way n | ||
| 683 | * (XCHAL_xTLB_SETm_PAGESZ_LOG2_LIST for set m corresponding to way n); | ||
| 684 | * this list may be sparse for auto-refill ways because auto-refill | ||
| 685 | * ways have independent lists of supported page sizes sharing a | ||
| 686 | * common encoding with PTE entries; the encoding is the index into | ||
| 687 | * this list; unsupported sizes for a given way are zero in the list; | ||
| 688 | * selecting unsupported sizes results in undefined hardware behaviour; | ||
| 689 | * - is only possible for ways 0 thru 7 (due to ITLBCFG/DTLBCFG definition). | ||

| 42 | * The index counts starting at zero for the lsbit, so the return | ||
| 43 | * value ranges from <base>-1 (no bit set) to <base>+31 (msbit set). | ||
| 44 | * | ||
| 45 | * Parameters: | ||
| 46 | * <ad> destination address register (any register) | ||
| 47 | * <as> source address register | ||
| 48 | * <at> temporary address register (must be different than <as>) | ||
| 49 | * <base> constant value added to result (usually 0 or 1) | ||
| 50 | * On entry: | ||
| 51 | * <ad> = undefined if different than <as> | ||
| 52 | * <as> = value whose most significant set bit is to be found | ||
| 53 | * <at> = undefined | ||
| 54 | * no other registers are used by this macro. | ||
| 55 | * On exit: | ||

| 126 | * floop, floopnez, floopgtz, floopend | ||
| 127 | * | ||
| 128 | * These macros are used for fast inner loops that | ||
| 129 | * work whether or not the Loops options is configured. | ||
| 130 | * If the Loops option is configured, they simply use | ||
| 131 | * the zero-overhead LOOP instructions; otherwise | ||
| 132 | * they use explicit decrement and branch instructions. | ||
| 133 | * | ||
| 134 | * They are used in pairs, with floop, floopnez or floopgtz | ||
| 135 | * at the beginning of the loop, and floopend at the end. | ||
| 136 | * | ||
| 137 | * Each pair of loop macro calls must be given the loop count | ||
| 138 | * address register and a unique label for that loop. | ||
| 139 | * | ||
| 140 | * Example: | ||
| 141 | * | ||
| 142 | * movi a3, 16 // loop 16 times | ||
| 143 | * floop a3, myloop1 | ||
| 144 | * : | ||
| 145 | * bnez a7, end1 // exit loop if a7 != 0 | ||
| 146 | * : | ||
| 147 | * floopend a3, myloop1 | ||
| 148 | * end1: | ||
| 149 | * | ||
| 150 | * Like the LOOP instructions, these macros cannot be | ||
| 151 | * nested, must include at least one instruction, | ||
| 152 | * cannot call functions inside the loop, etc. | ||
| 153 | * The loop can be exited by jumping to the instruction | ||
| 154 | * following floopend (or elsewhere outside the loop), | ||
| 155 | * or continued by jumping to a NOP instruction placed | ||
| 156 | * immediately before floopend. | ||
| 157 | * | ||
| 158 | * Unlike LOOP instructions, the register passed to floop* | ||
| 159 | * cannot be used inside the loop, because it is used as | ||
| 160 | * the loop counter if the Loops option is not configured. | ||
| 161 | * And its value is undefined after exiting the loop. | ||
| 162 | * And because the loop counter register is active inside | ||
| 163 | * the loop, you can't easily use this construct to loop | ||
| 164 | * across a register file using ROTW as you might with LOOP | ||
| 165 | * instructions, unless you copy the loop register along. | ||

| 64 | * Note: there is a distinction between the software release with | ||
| 65 | * which something is compiled (accessible using XTHAL_RELEASE_* macros) | ||
| 66 | * and the software release with which the HAL library was compiled | ||
| 67 | * (accessible using Xthal_release_* global variables). This | ||
| 68 | * distinction is particularly relevant for vendors that distribute | ||
| 69 | * configuration-independent binaries (eg. an OS), where their customer | ||
| 70 | * might link it with a HAL of a different Xtensa software release. | ||
| 71 | * In this case, it may be appropriate for the OS to verify at run-time | ||
| 72 | * whether XTHAL_RELEASE_* and Xthal_release_* are compatible. | ||
| 73 | * [Guidelines as to which release is compatible with which are not | ||
| 74 | * currently provided explicitly, but might be inferred from reading | ||
| 75 | * OSKit documentation for all releases -- compatibility is also highly | ||
| 76 | * dependent on which HAL features are used. Each release is usually | ||
| 77 | * backward compatible, with very few exceptions if any.] | ||

| 18 | * System call like services offered by the simulator host. | ||
| 19 | * These are modeled after the Linux 2.4 kernel system calls | ||
| 20 | * for Xtensa processors. However not all system calls and | ||
| 21 | * not all functionality of a given system call are implemented, | ||
| 22 | * or necessarily have well defined or equivalent semantics in | ||
| 23 | * the context of a simulation (as opposed to a Unix kernel). | ||
| 24 | * | ||
| 25 | * These services behave largely as if they had been invoked | ||
| 26 | * as a task in the simulator host's operating system | ||
| 27 | * (eg. files accessed are those of the simulator host). | ||
| 28 | * However, these SIMCALLs model a virtual operating system | ||
| 29 | * so that various definitions, bit assignments etc | ||
| 30 | * (eg. open mode bits, errno values, etc) are independent | ||
| 31 | * of the host operating system used to run the simulation. | ||
| 32 | * Rather these definitions are specific to the Xtensa ISS. | ||
| 33 | * This way Xtensa ISA code written to use these SIMCALLs | ||
| 34 | * can (in principle) be simulated on any host. | ||
| 35 | * | ||
| 36 | * Up to 6 parameters are passed in registers a3 to a8 | ||
| 37 | * (note the 6th parameter isn't passed on the stack, | ||
| 38 | * unlike windowed function calling conventions). | ||
| 39 | * The return value is in a2. A negative value in the | ||
| 40 | * range -4096 to -1 indicates a negated error code to be | ||
| 41 | * reported in errno with a return value of -1, otherwise | ||
| 42 | * the value in a2 is returned as is. | ||
