2 * IOMMU implementation for Cell Broadband Processor Architecture 2 * IOMMU implementation for Cell Broadband Processor Architecture
3 * We just establish a linear mapping at boot by setting all the
4 * IOPT cache entries in the CPU.
5 * The mapping functions should be identical to pci_direct_iommu,
6 * except for the handling of the high order bit that is required
7 * by the Spider bridge. These should be split into a separate
8 * file at the point where we get a different bridge chip.

10 This option is only for experts who may have the desire to fine
11 tune the pagetable size on their system. The value here is
12 expressed as the log2 of the page table size. Valid values are
13 18, 19, and 20, corresponding to 256KB, 512KB and 1MB respectively.

22 help
23 This option will enable kernel support to take advantage of the
24 per device dynamic DMA page table management provided by the Cell
25 processor's IO Controller. This support incurs some runtime
26 overhead and also slightly increases kernel memory usage. The
27 current implementation should be considered experimental.

30 say N.

37 This option is solely for experimentation by experts. Disables
38 translation of lpar addresses. SPE support currently won't work
39 without this set to y.

32 * address of the upper byte (leave NULL if using mc146818), and set
33 * 'nvram_data' to the address of the 8-bit data register.

36 * take up to a second before it starts updating once the 'R' bit is
37 * cleared, they always seem to update even though we bang on it many
38 * times a second. This is true, except for the Dallas Semi 1746/1747

55-=-=-= OPCODE =-=-=-
56
57OPCODE field specifies the most significant 11bit of the instruction. Some formats don't have 11bits for opcode field, and in this
58case, bit field other than op are defined as 0s. For example, opcode of fma instruction which is RRR format is defined as 0x700,
59since 0x700 -> 11'b11100000000, this means opcode is 4'b1110, and other 7bits are defined as 7'b0000000.

88
89Note that RRR instructions have the names for RC and RT reversed from
90what's in the ISA, in order to put RT in the same position it appears
91for other formats.
92
93-=-=-= DEPENDENCY =-=-=-
94
95DEPENDENCY filed consists of 5 digits. This represents which register is used as source and which register is used as target.
96The first(most significant) digit is always 0. Then it is followd by RC, RB, RA and RT digits.
97If the digit is 0, this means the corresponding register is not used in the instruction.
98If the digit is 1, this means the corresponding register is used as a source in the instruction.
99If the digit is 2, this means the corresponding register is used as a target in the instruction.
100If the digit is 3, this means the corresponding register is used as both source and target in the instruction.
101For example, fms instruction has 00113 as the DEPENDENCY field. This means RC is not used in this operation, RB and RA are
102used as sources and RT is the target.
103
104-=-=-= PIPE =-=-=-
105
106This field shows which execution pipe is used for the instruction
107

110 FP7 integer operations executed in SP floating pipeline
111 FPD DP floating pipeline
112 FX2 FXU pipeline
