The documentation is in a format that is very close to ReST format.

The conversion is actually:
  - add blank lines in order to identify paragraphs;
  - fixing tables markups;
  - adding some lists markups;
  - marking literal blocks;
  - adjust some title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

+Author: Catalin Marinas <catalin.marinas@arm.com>

+This document describes the virtual memory layout used by the AArch64
+Linux kernel. The architecture allows up to 4 levels of translation
+tables with a 4KB page size and up to 3 levels with a 64KB page size.
+
+AArch64 Linux uses either 3 levels or 4 levels of translation tables
+with the 4KB page configuration, allowing 39-bit (512GB) or 48-bit
+(256TB) virtual addresses, respectively, for both user and kernel. With
+64KB pages, only 2 levels of translation tables, allowing 42-bit (4TB)
+virtual address, are used but the memory layout is the same.
+
+User addresses have bits 63:48 set to 0 while the kernel addresses have
+the same bits set to 1. TTBRx selection is given by bit 63 of the
+virtual address. The swapper_pg_dir contains only kernel (global)
+mappings while the user pgd contains only user (non-global) mappings.

Convert kdump documentation to ReST and add it to the
user faced manual, as the documents are mainly focused on
sysadmins that would be enabling kdump.

Note: the vmcoreinfo.rst has one very long title on one of its
sub-sections:

	PG_lru|PG_private|PG_swapcache|PG_swapbacked|PG_slab|PG_hwpoision|PG_head_mask|PAGE_BUDDY_MAPCOUNT_VALUE(~PG_buddy)|PAGE_OFFLINE_MAPCOUNT_VALUE(~PG_offline)

I opted to break this one, into two entries with the same content,
in order to make it easier to display after being parsed in html and PDF.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Convert docs to ReST and add them to the arch-specific
book.

The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.

The changes were mostly to mark literal blocks and add a few
missing section title identifiers.

One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

+Ptrace

+
+GDB intends to support the following hardware debug features of BookE
+processors:
+
+4 hardware breakpoints (IAC)
+2 hardware watchpoints (read, write and read-write) (DAC)
+2 value conditions for the hardware watchpoints (DVC)
+
+For that, we need to extend ptrace so that GDB can query and set these
+resources. Since we're extending, we're trying to create an interface
+that's extendable and that covers both BookE and server processors, so
+that GDB doesn't need to special-case each of them. We added the
+following 3 new ptrace requests.
+
+1. PTRACE_PPC_GETHWDEBUGINFO
+============================
+
+Query for GDB to discover the hardware debug features. The main info to
+be returned here is the minimum alignment for the hardware watchpoints.
+BookE processors don't have restrictions here, but server processors have
+an 8-byte alignment restriction for hardware watchpoints. We'd like to avoid
+adding special cases to GDB based on what it sees in AUXV.
+
+Since we're at it, we added other useful info that the kernel can return to
+GDB: this query will return the number of hardware breakpoints, hardware
+watchpoints and whether it supports a range of addresses and a condition.
+The query will fill the following structure provided by the requesting process::
+
+  struct ppc_debug_info {
+       unit32_t version;
+       unit32_t num_instruction_bps;
+       unit32_t num_data_bps;
+       unit32_t num_condition_regs;
+       unit32_t data_bp_alignment;
+       unit32_t sizeof_condition; /* size of the DVC register */
+       uint64_t features; /* bitmask of the individual flags */
+  };
+
+features will have bits indicating whether there is support for::
+
+  #define PPC_DEBUG_FEATURE_INSN_BP_RANGE		0x1
+  #define PPC_DEBUG_FEATURE_INSN_BP_MASK		0x2
+  #define PPC_DEBUG_FEATURE_DATA_BP_RANGE		0x4
+  #define PPC_DEBUG_FEATURE_DATA_BP_MASK		0x8
+  #define PPC_DEBUG_FEATURE_DATA_BP_DAWR		0x10
+
+2. PTRACE_SETHWDEBUG
+
+Sets a hardware breakpoint or watchpoint, according to the provided structure::
+
+  struct ppc_hw_breakpoint {
+        uint32_t version;
+  #define PPC_BREAKPOINT_TRIGGER_EXECUTE  0x1
+  #define PPC_BREAKPOINT_TRIGGER_READ     0x2
+ #define PPC_BREAKPOINT_TRIGGER_WRITE    0x4
+        uint32_t trigger_type;       /* only some combinations allowed */
+  #define PPC_BREAKPOINT_MODE_EXACT               0x0
+  #define PPC_BREAKPOINT_MODE_RANGE_INCLUSIVE     0x1
+  #define PPC_BREAKPOINT_MODE_RANGE_EXCLUSIVE     0x2
+  #define PPC_BREAKPOINT_MODE_MASK                0x3
+        uint32_t addr_mode;          /* address match mode */
+
+  #define PPC_BREAKPOINT_CONDITION_MODE   0x3
+  #define PPC_BREAKPOINT_CONDITION_NONE   0x0
+  #define PPC_BREAKPOINT_CONDITION_AND    0x1
+  #define PPC_BREAKPOINT_CONDITION_EXACT  0x1	/* different name for the same thing as above */
+  #define PPC_BREAKPOINT_CONDITION_OR     0x2
+  #define PPC_BREAKPOINT_CONDITION_AND_OR 0x3
+  #define PPC_BREAKPOINT_CONDITION_BE_ALL 0x00ff0000	/* byte enable bits */
+  #define PPC_BREAKPOINT_CONDITION_BE(n)  (1<<((n)+16))
+        uint32_t condition_mode;     /* break/watchpoint condition flags */
+
+        uint64_t addr;
+        uint64_t addr2;
+        uint64_t condition_value;
+  };
+
+A request specifies one event, not necessarily just one register to be set.
+For instance, if the request is for a watchpoint with a condition, both the
+DAC and DVC registers will be set in the same request.
+
+With this GDB can ask for all kinds of hardware breakpoints and watchpoints
+that the BookE supports. COMEFROM breakpoints available in server processors
+are not contemplated, but that is out of the scope of this work.
+
+ptrace will return an integer (handle) uniquely identifying the breakpoint or
+watchpoint just created. This integer will be used in the PTRACE_DELHWDEBUG
+request to ask for its removal. Return -ENOSPC if the requested breakpoint
+can't be allocated on the registers.
+
+Some examples of using the structure to:
+
+- set a breakpoint in the first breakpoint register::
+
+    p.version         = PPC_DEBUG_CURRENT_VERSION;
+    p.trigger_type    = PPC_BREAKPOINT_TRIGGER_EXECUTE;
+    p.addr_mode       = PPC_BREAKPOINT_MODE_EXACT;
+    p.condition_mode  = PPC_BREAKPOINT_CONDITION_NONE;
+    p.addr            = (uint64_t) address;
+    p.addr2           = 0;
+    p.condition_value = 0;
+
+- set a watchpoint which triggers on reads in the second watchpoint register::
+
+    p.version         = PPC_DEBUG_CURRENT_VERSION;
+    p.trigger_type    = PPC_BREAKPOINT_TRIGGER_READ;

+
+    p.version         = PPC_DEBUG_CURRENT_VERSION;
+    p.trigger_type    = PPC_BREAKPOINT_TRIGGER_READ;

+    p.addr            = (uint64_t) address;
+    p.addr2           = 0;
+    p.condition_value = (uint64_t) condition;
+
+- set a ranged hardware breakpoint::
+
+    p.version         = PPC_DEBUG_CURRENT_VERSION;
+    p.trigger_type    = PPC_BREAKPOINT_TRIGGER_EXECUTE;
+    p.addr_mode       = PPC_BREAKPOINT_MODE_RANGE_INCLUSIVE;
+    p.condition_mode  = PPC_BREAKPOINT_CONDITION_NONE;
+    p.addr            = (uint64_t) begin_range;
+    p.addr2           = (uint64_t) end_range;
+    p.condition_value = 0;
+
+- set a watchpoint in server processors (BookS)::
+
+    p.version         = 1;
+    p.trigger_type    = PPC_BREAKPOINT_TRIGGER_RW;
+    p.addr_mode       = PPC_BREAKPOINT_MODE_RANGE_INCLUSIVE;
+    or
+    p.addr_mode       = PPC_BREAKPOINT_MODE_EXACT;
+
+    p.condition_mode  = PPC_BREAKPOINT_CONDITION_NONE;

This is a very trivial conversion: adjust the title markup
and add a few literal block markups to produce a better
visual when parsed and avoid warnings.

As newer documents related to xilinx could be added in the future,
create a new index file for it.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

I think that should be a period, not a colon, because it is clarifying
the text above it (as opposed to referring to the example below it).

Ah, ok. I'll change it to:

	after the entire cycle is complete (i.e., suspend + resume).

This one doesn't apply to docs-next, since there's a bunch of stuff in
linux-next that I don't have.  I'd suggest that it either go by way of an
ARM tree or send it my way again after the ARM changes go upstream.

Thanks,

jon

Actually, nevermind.  Pulling my tree forward to 5.2-rc4 resolved the
issues here.

OK, I applied this to pci/docs for v5.3.  I applied this entire patch,
but if you would prefer that I only apply the PCI-related parts, let
me know and I'll split those out.

I don't see these conflict markers in my local branch or in
linux-next (next-20190614).

Let me know if I need to do something.

I don't think so.

There's some other uses of >>> in that file, eg about line 162:

  >>> The current powerpc implementation assumes that a device driver will
  >>> *not* schedule or semaphore in this routine; the current powerpc
  >>> implementation uses one kernel thread to notify all devices;
  >>> thus, if one device sleeps/schedules, all devices are affected.
  >>> Doing better requires complex multi-threaded logic in the error
  >>> recovery implementation (e.g. waiting for all notification threads
  >>> to "join" before proceeding with recovery.)  This seems excessively
  >>> complex and not worth implementing.


So it's just an odd choice of emphasis device I think.

cheers
