265 * mmu_map/unmap are provided by iommu/iounit; Invalid to call on IIep.
266 *
267 * The mmu_map_dma_area establishes two mappings in one go.
268 * These mappings point to pages normally mapped at 'va' (linear address).
269 * First mapping is for CPU visible address at 'a', uncached.
270 * This is an alias, but it works because it is an uncached mapping.
271 * Second mapping is for device visible address, or "bus" address.
272 * The bus address is returned at '*pba'.
273 *
274 * These functions seem distinct, but are hard to split. On sun4c,
275 * at least for now, 'a' is equal to bus address, and retured in *pba.
276 * On sun4m, page attributes depend on the CPU type, so we have to
277 * know if we are mapping RAM or I/O, so it has to be an additional argument
278 * to a separate mapping function for CPU visible mappings.

17 *
18 * The driver supports 4 operations: open(), close(), ioctl(), read()
19 * The device name is /dev/envctrl.
20 * Below is sample usage:
21 *
22 * fd = open("/dev/envtrl", O_RDONLY);
23 * if (ioctl(fd, ENVCTRL_READ_SHUTDOWN_TEMPERATURE, 0) < 0)
24 * printf("error\n");
25 * ret = read(fd, buf, 10);
26 * close(fd);
27 *
28 * Notice in the case of cpu voltage and temperature, the default is
29 * cpu0. If we need to know the info of cpu1, cpu2, cpu3, we need to
30 * pass in cpu number in ioctl() last parameter. For example, to
31 * get the voltage of cpu2:
32 *
33 * ioctlbuf[0] = 2;
34 * if (ioctl(fd, ENVCTRL_READ_CPU_VOLTAGE, ioctlbuf) < 0)
35 * printf("error\n");
36 * ret = read(fd, buf, 10);
37 *
38 * All the return values are in ascii. So check read return value
39 * and do appropriate conversions in your application.

4/* Sun4v hypervisor interfaces and defines.
5 *
6 * Hypervisor calls are made via traps to software traps number 0x80
7 * and above. Registers %o0 to %o5 serve as argument, status, and
8 * return value registers.
9 *
10 * There are two kinds of these traps. First there are the normal
11 * "fast traps" which use software trap 0x80 and encode the function
12 * to invoke by number in register %o5. Argument and return value
13 * handling is as follows:
14 *
15 * -----------------------------------------------
16 * | %o5 | function number | undefined |
17 * | %o0 | argument 0 | return status |
18 * | %o1 | argument 1 | return value 1 |
19 * | %o2 | argument 2 | return value 2 |
20 * | %o3 | argument 3 | return value 3 |
21 * | %o4 | argument 4 | return value 4 |
22 * -----------------------------------------------
23 *
24 * The second type are "hyper-fast traps" which encode the function
25 * number in the software trap number itself. So these use trap
26 * numbers > 0x80. The register usage for hyper-fast traps is as
27 * follows:
28 *
29 * -----------------------------------------------
30 * | %o0 | argument 0 | return status |
31 * | %o1 | argument 1 | return value 1 |
32 * | %o2 | argument 2 | return value 2 |
33 * | %o3 | argument 3 | return value 3 |
34 * | %o4 | argument 4 | return value 4 |
35 * -----------------------------------------------
36 *
37 * Registers providing explicit arguments to the hypervisor calls
38 * are volatile across the call. Upon return their values are
39 * undefined unless explicitly specified as containing a particular
40 * return value by the specific call. The return status is always
41 * returned in register %o0, zero indicates a successful execution of
42 * the hypervisor call and other values indicate an error status as
43 * defined below. So, for example, if a hyper-fast trap takes
44 * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
45 * the call and %o3, %o4, and %o5 would be preserved.
46 *
47 * If the hypervisor trap is invalid, or the fast trap function number
48 * is invalid, HV_EBADTRAP will be returned in %o0. Also, all 64-bits
49 * of the argument and return values are significant.

160 *
161 * A guest uses this API to set a watchdog timer. Once the gues has set
162 * the timer, it must call the timer service again either to disable or
163 * postpone the expiration. If the timer expires before being reset or
164 * disabled, then the hypervisor take a platform specific action leading
165 * to guest termination within a bounded time period. The platform action
166 * may include recovery actions such as reporting the expiration to a
167 * Service Processor, and/or automatically restarting the gues.
168 *
169 * The 'timeout' parameter is specified in milliseconds, however the
170 * implementated granularity is given by the 'watchdog-resolution'
171 * property in the 'platform' node of the guest's machine description.
172 * The largest allowed timeout value is specified by the
173 * 'watchdog-max-timeout' property of the 'platform' node.
174 *
175 * If the 'timeout' argument is not zero, the watchdog timer is set to
176 * expire after a minimum of 'timeout' milliseconds.
177 *
178 * If the 'timeout' argument is zero, the watchdog timer is disabled.
179 *
180 * If the 'timeout' value exceeds the value of the 'max-watchdog-timeout'
181 * property, the hypervisor leaves the watchdog timer state unchanged,
182 * and returns a status of EINVAL.
183 *
184 * The 'time remaining' return value is valid regardless of whether the
185 * return status is EOK or EINVAL. A non-zero return value indicates the
186 * number of milliseconds that were remaining until the timer was to expire.
187 * If less than one millisecond remains, the return value is '1'. If the
188 * watchdog timer was disabled at the time of the call, the return value is
189 * zero.
190 *
191 * If the hypervisor cannot support the exact timeout value requested, but
192 * can support a larger timeout value, the hypervisor may round the actual
193 * timeout to a value larger than the requested timeout, consequently the
194 * 'time remaining' return value may be larger than the previously requested
195 * timeout value.
196 *
197 * Any guest OS debugger should be aware that the watchdog service may be in
198 * use. Consequently, it is recommended that the watchdog service is
199 * disabled upon debugger entry (e.g. reaching a breakpoint), and then
200 * re-enabled upon returning to normal execution. The API has been designed
201 * with this in mind, and the 'time remaining' result of the disable call may
202 * be used directly as the timeout argument of the re-enable call.

1676/* PCI IO services.
1677 *
1678 * See the terminology descriptions in the device interrupt services
1679 * section above as those apply here too. Here are terminology
1680 * definitions specific to these PCI IO services:
1681 *
1682 * tsbnum TSB number. Indentifies which io-tsb is used.
1683 * For this version of the specification, tsbnum
1684 * must be zero.
1685 *
1686 * tsbindex TSB index. Identifies which entry in the TSB
1687 * is used. The first entry is zero.
1688 *
1689 * tsbid A 64-bit aligned data structure which contains
1690 * a tsbnum and a tsbindex. Bits 63:32 contain the
1691 * tsbnum and bits 31:00 contain the tsbindex.
1692 *
1693 * Use the HV_PCI_TSBID() macro to construct such
1694 * values.
1695 *
1696 * io_attributes IO attributes for IOMMU mappings. One of more
1697 * of the attritbute bits are stores in a 64-bit
1698 * value. The values are defined below.
1699 *
1700 * r_addr 64-bit real address
1701 *
1702 * pci_device PCI device address. A PCI device address identifies
1703 * a specific device on a specific PCI bus segment.
1704 * A PCI device address ia a 32-bit unsigned integer
1705 * with the following format:
1706 *
1707 * 00000000.bbbbbbbb.dddddfff.00000000
1708 *
1709 * Use the HV_PCI_DEVICE_BUILD() macro to construct
1710 * such values.
1711 *
1712 * pci_config_offset
1713 * PCI configureation space offset. For conventional
1714 * PCI a value between 0 and 255. For extended
1715 * configuration space, a value between 0 and 4095.
1716 *
1717 * Note: For PCI configuration space accesses, the offset
1718 * must be aligned to the access size.
1719 *
1720 * error_flag A return value which specifies if the action succeeded
1721 * or failed. 0 means no error, non-0 means some error
1722 * occurred while performing the service.
1723 *
1724 * io_sync_direction
1725 * Direction definition for pci_dma_sync(), defined
1726 * below in HV_PCI_SYNC_*.
1727 *
1728 * io_page_list A list of io_page_addresses, an io_page_address is
1729 * a real address.
1730 *
1731 * io_page_list_p A pointer to an io_page_list.
1732 *
1733 * "size based byte swap" - Some functions do size based byte swapping
1734 * which allows sw to access pointers and
1735 * counters in native form when the processor
1736 * operates in a different endianness than the
1737 * IO bus. Size-based byte swapping converts a
1738 * multi-byte field between big-endian and
1739 * little-endian format.

193 * The first two TLBs are fully assosciative, hold 16 entries, and are
194 * used only for locked and >8K sized translations. One exists for
195 * data accesses and one for instruction accesses.
196 *
197 * The third TLB is for data accesses to 8K non-locked translations, is
198 * 2 way assosciative, and holds 512 entries. The fourth TLB is for
199 * instruction accesses to 8K non-locked translations, is 2 way
200 * assosciative, and holds 128 entries.
201 *
202 * Cheetah has some bug where bogus data can be returned from
203 * ASI_{D,I}TLB_DATA_ACCESS loads, doing the load twice fixes
204 * the problem for me. -DaveM

4/* The sparc64 TSB is similar to the powerpc hashtables. It's a
5 * power-of-2 sized table of TAG/PTE pairs. The cpu precomputes
6 * pointers into this table for 8K and 64K page sizes, and also a
7 * comparison TAG based upon the virtual address and context which
8 * faults.
9 *
10 * TLB miss trap handler software does the actual lookup via something
11 * of the form:
12 *
13 * ldxa [%g0] ASI_{D,I}MMU_TSB_8KB_PTR, %g1
14 * ldxa [%g0] ASI_{D,I}MMU, %g6
15 * sllx %g6, 22, %g6
16 * srlx %g6, 22, %g6
17 * ldda [%g1] ASI_NUCLEUS_QUAD_LDD, %g4
18 * cmp %g4, %g6
19 * bne,pn %xcc, tsb_miss_{d,i}tlb
20 * mov FAULT_CODE_{D,I}TLB, %g3
21 * stxa %g5, [%g0] ASI_{D,I}TLB_DATA_IN
22 * retry
23 *
24 *
25 * Each 16-byte slot of the TSB is the 8-byte tag and then the 8-byte
26 * PTE. The TAG is of the same layout as the TLB TAG TARGET mmu
27 * register which is:
28 *
29 * -------------------------------------------------
30 * | - | CONTEXT | - | VADDR bits 63:22 |
31 * -------------------------------------------------
32 * 63 61 60 48 47 42 41 0
33 *
34 * But actually, since we use per-mm TSB's, we zero out the CONTEXT
35 * field.
36 *
37 * Like the powerpc hashtables we need to use locking in order to
38 * synchronize while we update the entries. PTE updates need locking

204/* Before touching these macros, you owe it to yourself to go and
205 * see how arch/sparc64/kernel/winfixup.S works... -DaveM
206 *
207 * For the user cases we used to use the %asi register, but
208 * it turns out that the "wr xxx, %asi" costs ~5 cycles, so
209 * now we use immediate ASI loads and stores instead. Kudos
210 * to Greg Onufer for pointing out this performance anomaly.
211 *
212 * Further note that we cannot use the g2, g4, g5, and g7 alternate
213 * globals in the spill routines, check out the save instruction in
214 * arch/sparc64/kernel/etrap.S to see what I mean about g2, and
215 * g4/g5 are the globals which are preserved by etrap processing
216 * for the caller of it. The g7 register is the return pc for
217 * etrap. Finally, g6 is the current thread register so we cannot
218 * us it in the spill handlers either. Most of these rules do not
219 * apply to fill processing, only g6 is not usable.

14/* Bits in the SRMMU control register for GNU/Viking modules.
15 *
16 * -----------------------------------------------------------
17 * |impl-vers| RSV |TC|AC|SP|BM|PC|MBM|SB|IC|DC|PSO|RSV|NF|ME|
18 * -----------------------------------------------------------
19 * 31 24 23-17 16 15 14 13 12 11 10 9 8 7 6-2 1 0
20 *
21 * TC: Tablewalk Cacheable -- 0 = Twalks are not cacheable in E-cache
22 * 1 = Twalks are cacheable in E-cache
23 *
24 * GNU/Viking will only cache tablewalks in the E-cache (mxcc) if present
25 * and never caches them internally (or so states the docs). Therefore
26 * for machines lacking an E-cache (ie. in MBUS mode) this bit must
27 * remain cleared.
28 *
29 * AC: Alternate Cacheable -- 0 = Passthru physical accesses not cacheable
30 * 1 = Passthru physical accesses cacheable
31 *
32 * This indicates whether accesses are cacheable when no cachable bit
33 * is present in the pte when the processor is in boot-mode or the
34 * access does not need pte's for translation (ie. pass-thru ASI's).
35 * "Cachable" is only referring to E-cache (if present) and not the
36 * on chip split I/D caches of the GNU/Viking.
37 *
38 * SP: SnooP Enable -- 0 = bus snooping off, 1 = bus snooping on
39 *
40 * This enables snooping on the GNU/Viking bus. This must be on
41 * for the hardware cache consistency mechanisms of the GNU/Viking
42 * to work at all. On non-mxcc GNU/Viking modules the split I/D
43 * caches will snoop regardless of whether they are enabled, this
44 * takes care of the case where the I or D or both caches are turned
45 * off yet still contain valid data. Note also that this bit does
46 * not affect GNU/Viking store-buffer snoops, those happen if the
47 * store-buffer is enabled no matter what.
48 *
49 * BM: Boot Mode -- 0 = not in boot mode, 1 = in boot mode
50 *
51 * This indicates whether the GNU/Viking is in boot-mode or not,
52 * if it is then all instruction fetch physical addresses are
53 * computed as 0xff0000000 + low 28 bits of requested address.
54 * GNU/Viking boot-mode does not affect data accesses. Also,
55 * in boot mode instruction accesses bypass the split on chip I/D
56 * caches, they may be cached by the GNU/MXCC if present and enabled.
57 *
58 * MBM: MBus Mode -- 0 = not in MBus mode, 1 = in MBus mode
59 *
60 * This indicated the GNU/Viking configuration present. If in
61 * MBUS mode, the GNU/Viking lacks a GNU/MXCC E-cache. If it is
62 * not then the GNU/Viking is on a module VBUS connected directly
63 * to a GNU/MXCC cache controller. The GNU/MXCC can be thus connected
64 * to either an GNU/MBUS (sun4m) or the packet-switched GNU/XBus (sun4d).
65 *
66 * SB: StoreBuffer enable -- 0 = store buffer off, 1 = store buffer on
67 *
68 * The GNU/Viking store buffer allows the chip to continue execution
69 * after a store even if the data cannot be placed in one of the
70 * caches during that cycle. If disabled, all stores operations
71 * occur synchronously.
72 *
73 * IC: Instruction Cache -- 0 = off, 1 = on
74 * DC: Data Cache -- 0 = off, 1 = 0n
75 *
76 * These bits enable the on-cpu GNU/Viking split I/D caches. Note,
77 * as mentioned above, these caches will snoop the bus in GNU/MBUS
78 * configurations even when disabled to avoid data corruption.
79 *
80 * NF: No Fault -- 0 = faults generate traps, 1 = faults don't trap
81 * ME: MMU enable -- 0 = mmu not translating, 1 = mmu translating
82 *
