These structures are used for commands to the + * PKO, ZIP, DFA, RAID, and DMA engine blocks. Although each + * hardware unit takes commands and CSRs of different types, + * they all use basic linked command buffers to store the + * pending request. In general, users of the CVMX API don't + * call cvmx-cmd-queue functions directly. Instead the hardware + * unit specific wrapper should be used. The wrappers perform + * unit specific validation and CSR writes to submit the + * commands. + * + * Even though most software will never directly interact with + * cvmx-cmd-queue, knowledge of its internal working can help + * in diagnosing performance problems and help with debugging. + * + * Command queue pointers are stored in a global named block + * called "cvmx_cmd_queues". Except for the PKO queues, each + * hardware queue is stored in its own cache line to reduce SMP + * contention on spin locks. The PKO queues are stored such that + * every 16th queue is next to each other in memory. This scheme + * allows for queues being in separate cache lines when there + * are low number of queues per port. With 16 queues per port, + * the first queue for each port is in the same cache area. The + * second queues for each port are in another area, etc. This + * allows software to implement very efficient lockless PKO with + * 16 queues per port using a minimum of cache lines per core. + * All queues for a given core will be isolated in the same + * cache area. + * + * In addition to the memory pointer layout, cvmx-cmd-queue + * provides an optimized fair ll/sc locking mechanism for the + * queues. The lock uses a "ticket / now serving" model to + * maintain fair order on contended locks. In addition, it uses + * predicted locking time to limit cache contention. When a core + * know it must wait in line for a lock, it spins on the + * internal cycle counter to completely eliminate any causes of + * bus traffic. + * + */ + +#ifndef __CVMX_CMD_QUEUE_H__ +#define __CVMX_CMD_QUEUE_H__ + +#include + +#include + +#include +/** + * By default we disable the max depth support.

CVMX_PKO_LOCK_ATOMIC_TAG continues to + * function similarly to previous SDKs by using POW atomic tags + * to preserve ordering and exclusivity. As a new option, you + * can now pass CVMX_PKO_LOCK_CMD_QUEUE which uses a ll/sc + * memory based locking instead. This locking has the advantage + * of not affecting the tag state but doesn't preserve packet + * ordering. CVMX_PKO_LOCK_CMD_QUEUE is appropriate in most + * generic code while CVMX_PKO_LOCK_CMD_QUEUE should be used + * with hand tuned fast path code. + * + * Some of other SDK differences visible to the command queuing: + * - PKO indexes are no longer stored in the FAU. A large + * percentage of the FAU register block used to be tied up + * maintaining PKO queue pointers. These are now stored in a + * global named block. + * - The PKO use_locking parameter can now have a global + * effect. Since all application use the same named block, + * queue locking correctly applies across all operating + * systems when using CVMX_PKO_LOCK_CMD_QUEUE. + * - PKO 3 word commands are now supported.

For example, + * the MAC registers are described as offsets from the first + * MAC register, and there will be a MAC_REGISTER() macro + * to calculate the base address of a given MAC. + * + * The information in this file is based on the BCM1X55/BCM1X80 + * User Manual, Document 1X55_1X80-UM100-R, 22/12/03. + * + * This file is basically a "what's new" header file. Since the + * BCM1250 and the new BCM1480 (and derivatives) share many common + * features, this file contains only what's new or changed from + * the 1250. (above, you can see that we include the 1250 symbols + * to get the base functionality). + * + * In software, be sure to use the correct symbols, particularly + * for blocks that are different between the two chip families. + * All BCM1480-specific symbols have _BCM1480_ in their names, + * and all BCM1250-specific and "base" functions that are common in + * both chips have no special names (this is for compatibility with + * older include files). Therefore, if you're working with the + * SCD, which is very different on each chip, A_SCD_xxx implies + * the BCM1250 version and A_BCM1480_SCD_xxx implies the BCM1480 + * version. +

Thus we need to take the approach of actually + * executing the instruction. + * + * - We must execute the instruction within user context. If we were to + * execute the instruction in kernel mode then it would have access to + * kernel resources without very careful checks, leaving us with a + * high potential for security or stability issues to arise. + * + * - We used to place the frame on the users stack, but this requires + * that the stack be executable. This is bad for security so the + * per-process page is now used instead. + * + * - The instruction in @emul may be something entirely invalid for a + * delay slot. The user may (intentionally or otherwise) place a branch + * in a delay slot, or a kernel mode instruction, or something else + * which generates an exception. Thus we can't rely upon the break in + * @badinst always being hit. For this reason we track the index of the + * frame allocated to each thread, allowing us to clean it up at later + * points such as signal delivery or thread exit. + * + * - The user may generate a fake struct emuframe if they wish, invoking + * the BRK_MEMU break instruction themselves. We must therefore not + * trust that BRK_MEMU means there's actually a valid frame allocated + * to the thread, and must not allow the user to do anything they + * couldn't already. + */ +struct emuframe { + mips_instruction emul; + mips_instruction badinst; +}; + +static const int emupage_frame_count = PAGE_SIZE / sizeof(struct emuframe); + +static inline __user struct emuframe *dsemul_page(void) +{ + return (__user struct emuframe *)STACK_TOP; +} + +static int alloc_emuframe(void) +{ + mm_context_t *mm_ctx = ¤t->mm->context; + int idx; + +retry: + spin_lock(&mm_ctx->bd_emupage_lock); + + /* Ensure we have an allocation bitmap */ + if (!mm_ctx->bd_emupage_allocmap) { + mm_ctx->bd_emupage_allocmap = bitmap_zalloc(emupage_frame_count, + GFP_ATOMIC); + if (!mm_ctx->bd_emupage_allocmap) { + idx = BD_EMUFRAME_NONE; + goto out_unlock; + } + } + + /* Attempt to allocate a single bit/frame */ + idx = bitmap_find_free_region(mm_ctx->bd_emupage_allocmap, + emupage_frame_count, 0); + if (idx < 0) { + /* + * Failed to allocate a frame.

The functions use shared operations + * where possible, and implement the rest for 32-bit MIPS such as ALU64 + * operations. + * + * - bpf_jit_comp64.c + * Ditto, for 64-bit MIPS CPUs. + * + * Zero and sign extension + * ======================== + * 32-bit MIPS instructions on 64-bit MIPS registers use sign extension, + * but the eBPF instruction set mandates zero extension. We let the verifier + * insert explicit zero-extensions after 32-bit ALU operations, both for + * 32-bit and 64-bit MIPS JITs. Conditional JMP32 operations on 64-bit MIPs + * are JITed with sign extensions inserted when so expected. + * + * ALU operations + * ============== + * ALU operations on 32/64-bit MIPS and ALU64 operations on 64-bit MIPS are + * JITed in the following steps. ALU64 operations on 32-bit MIPS are more + * complicated and therefore only processed by special implementations in + * step (3). + * + * 1) valid_alu_i: + * Determine if an immediate operation can be emitted as such, or if + * we must fall back to the register version. + * + * 2) rewrite_alu_i: + * Convert BPF operation and immediate value to a canonical form for + * JITing. In some degenerate cases this form may be a no-op. + * + * 3) emit_alu_{i,i64,r,64}: + * Emit instructions for an ALU or ALU64 immediate or register operation. + * + * JMP operations + * ============== + * JMP and JMP32 operations require an JIT instruction offset table for + * translating the jump offset. This table is computed by dry-running the + * JIT without actually emitting anything. However, the computed PC-relative + * offset may overflow the 18-bit offset field width of the native MIPS + * branch instruction. In such cases, the long jump is converted into the + * following sequence. + * + * ! +2 Inverted PC-relative branch + * nop Delay slot + * j Unconditional absolute long jump + * nop Delay slot + * + * Since this converted sequence alters the offset table, all offsets must + * be re-calculated. This may in turn trigger new branch conversions, so + * the process is repeated until no further changes are made. Normally it + * completes in 1-2 iterations. If JIT_MAX_ITERATIONS should reached, we + * fall back to converting every remaining jump operation. The branch + * conversion is independent of how the JMP or JMP32 condition is JITed. + * + * JMP32 and JMP operations are JITed as follows. + * + * 1) setup_jmp_{i,r}: + * Convert jump conditional and offset into a form that can be JITed. + * This form may be a no-op, a canonical form, or an inverted PC-relative + * jump if branch conversion is necessary. + * + * 2) valid_jmp_i: + * Determine if an immediate operations can be emitted as such, or if + * we must fall back to the register version.
