In-Reply-To: <20200514170327.31389-1-rppt@kernel.org>

From: Mike Rapoport <rppt@linux.ibm.com>

The comment about page table allocation functions resides in
include/asm/motorola_pgtable.h while the functions live in
include/asm/motorola_pgaloc.h.

Move the comment close to the code.

All architectures use pXd_index() to get an entry in the page table page
corresponding to a virtual address.

Align csky with other architectures.

In-Reply-To: <20200514170327.31389-1-rppt@kernel.org>

From: Mike Rapoport <rppt@linux.ibm.com>

The replacement of <asm/pgrable.h> with <linux/pgtable.h> made the include
of the latter in the middle of asm includes. Fix this up with the aid of
the below script and manual adjustments here and there.

	import sys
	import re

	if len(sys.argv) is not 3:
	    print "USAGE: %s <file> <header>" % (sys.argv[0])
	    sys.exit(1)

	hdr_to_move="#include <linux/%s>" % sys.argv[2]
	moved = False
	in_hdrs = False

	with open(sys.argv[1], "r") as f:
	    lines = f.readlines()
	    for _line in lines:
		line = _line.rstrip('\n')
		if line == hdr_to_move:
		    continue
		if line.startswith("#include <linux/"):
		    in_hdrs = True
		elif not moved and in_hdrs:
		    moved = True
		    print hdr_to_move
		print line

In-Reply-To: <20200514170327.31389-1-rppt@kernel.org>

From: Mike Rapoport <rppt@linux.ibm.com>

The include/linux/pgtable.h is going to be the home of generic page table
manipulation functions.
Start with moving asm-generic/pgtable.h to include/linux/pgtable.h and make
the latter include asm/pgtable.h.

In-Reply-To: <20200514170327.31389-1-rppt@kernel.org>

From: Mike Rapoport <rppt@linux.ibm.com>

The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g. pte_alloc() and
pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h> in
the files that include <linux/mm.h>.

The include statements in such cases are remove with a simple loop:

	for f in $(git grep -l "include <linux/mm.h>") ; do
		sed -i -e '/include <asm\/pgtable.h>/ d' $f
	done

From: Mike Rapoport <rppt@linux.ibm.com>

Hi,

The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once. For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.

Most of these definitions are actually identical and typically it boils
down to, e.g. 

static inline unsigned long pmd_index(unsigned long address)
{
        return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}

static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
        return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}

These definitions can be shared among 90% of the arches provided XYZ_SHIFT,
PTRS_PER_XYZ and xyz_page_vaddr() are defined.

For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.

These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.

The patches are vs the v5.7-rc5-mmotm-2020-05-13-20-30

v2 changes:
* s/morotola/motorola in the changelog of patch 6
* replace FIXME with a comment about pmf_off and virt_to_kpte in patch 8
* rebase on v5.7-rc5-mmotm-2020-05-13-20-30

Mike Rapoport (12):
  mm: don't include asm/pgtable.h if linux/mm.h is already included
  mm: introduce include/linux/pgtable.h
  mm: reorder includes after introduction of linux/pgtable.h
  csky: replace definitions of __pXd_offset() with pXd_index()
  m68k/mm/motorola: move comment about page table allocation funcitons
  m68k/mm: move {cache,nocahe}_page() definitions close to their user
  x86/mm: simplify init_trampoline() and surrounding logic
  mm: pgtable: add shortcuts for accessing kernel PMD and PTE
  mm: consolidate pte_index() and pte_offset_*() definitions
  mm: consolidate pmd_index() and pmd_offset() definitions
  mm: consolidate pud_index() and pud_offset() definitions
  mm: consolidate pgd_index() and pgd_offset{_k}() definitions

Sorry it is not very clear, r4 was always being used.
patch_imm32_load_insns() hardcoded r4. We now need to load 64 bits as
we just introduced prefixed instruction, so are using
patch_imm64_load_insns(). That is the connection to the patch. But a
separate patch and description would probably make that clearer.

Perhaps I am missing something, but it seems reasonable enough to me that you 
would introduce the machinery for dealing with prefix instructions prior to 
defining them. What would be the advantage of doing things the other way 
around?

Is there a particular reason you think it needs to go before patch 23? Neither 
seem particularly related to one another and it seems logical to me at least 
that you would introduce prefix support to the datatype prior to using them.

Xmon allows overwriting breakpoints because it's supported by only
one DAWR. But with multiple DAWRs, overwriting becomes ambiguous
or unnecessary complicated. So let's not allow it.

* [PATCH v6 14/16] powerpc/watchpoint: Don't allow concurrent perf and ptrace events
From: Ravi Bangoria @ 2020-05-14 11:17 UTC (permalink / raw)
  To: mpe, mikey
  Cc: christophe.leroy, apopple, ravi.bangoria, peterz, fweisbec, oleg,

In-Reply-To: <20200514111741.97993-1-ravi.bangoria@linux.ibm.com>

With Book3s DAWR, ptrace and perf watchpoints on powerpc behaves
differently. Ptrace watchpoint works in one-shot mode and generates
signal before executing instruction. It's ptrace user's job to
single-step the instruction and re-enable the watchpoint. OTOH, in
case of perf watchpoint, kernel emulates/single-steps the instruction
and then generates event. If perf and ptrace creates two events with
same or overlapping address ranges, it's ambiguous to decide who
should single-step the instruction. Because of this issue, don't
allow perf and ptrace watchpoint at the same time if their address
range overlaps.

* [PATCH v6 13/16] powerpc/watchpoint: Prepare handler to handle more than one watcnhpoint

In-Reply-To: <20200514111741.97993-1-ravi.bangoria@linux.ibm.com>

Currently we assume that we have only one watchpoint supported by hw.
Get rid of that assumption and use dynamic loop instead. This should
make supporting more watchpoints very easy.

With more than one watchpoint, exception handler needs to know which
DAWR caused the exception, and hw currently does not provide it. So
we need sw logic for the same. To figure out which DAWR caused the
exception, check all different combinations of user specified range,
DAWR address range, actual access range and DAWRX constrains. For ex,
if user specified range and actual access range overlaps but DAWRX is
configured for readonly watchpoint and the instruction is store, this
DAWR must not have caused exception.

* [PATCH v6 12/16] powerpc/watchpoint: Use builtin ALIGN*() macros
From: Ravi Bangoria @ 2020-05-14 11:17 UTC (permalink / raw)

  Cc: christophe.leroy, apopple, ravi.bangoria, peterz, fweisbec, oleg,
	npiggin, linux-kernel, paulus, jolsa, naveen.n.rao, linuxppc-dev,
	mingo
In-Reply-To: <20200514111741.97993-1-ravi.bangoria@linux.ibm.com>

Currently we calculate hw aligned start and end addresses manually.
Replace them with builtin ALIGN_DOWN() and ALIGN() macros.

So far end_addr was inclusive but this patch makes it exclusive (by
avoiding -1) for better readability.

* [PATCH v6 10/16] powerpc/watchpoint: Use loop for thread_struct->ptrace_bps
From: Ravi Bangoria @ 2020-05-14 11:17 UTC (permalink / raw)

  Cc: christophe.leroy, apopple, ravi.bangoria, peterz, fweisbec, oleg,

In-Reply-To: <20200514111741.97993-1-ravi.bangoria@linux.ibm.com>

ptrace_bps is already an array of size HBP_NUM_MAX. But we use
hardcoded index 0 while fetching/updating it. Convert such code
to loop over array.

ptrace interface to use multiple watchpoint remains same. eg:
two PPC_PTRACE_SETHWDEBUG calls will create two watchpoint if
underneath hw supports it.

* [PATCH v6 09/16] powerpc/watchpoint: Convert thread_struct->hw_brk to an array
From: Ravi Bangoria @ 2020-05-14 11:17 UTC (permalink / raw)

In-Reply-To: <20200514111741.97993-1-ravi.bangoria@linux.ibm.com>

So far powerpc hw supported only one watchpoint. But Power10 is
introducing 2nd DAWR. Convert thread_struct->hw_brk into an array.

* [PATCH v6 08/16] powerpc/watchpoint: Disable all available watchpoints when !dawr_force_enable
From: Ravi Bangoria @ 2020-05-14 11:17 UTC (permalink / raw)

  Cc: christophe.leroy, apopple, ravi.bangoria, peterz, fweisbec, oleg,

In-Reply-To: <20200514111741.97993-1-ravi.bangoria@linux.ibm.com>

Instead of disabling only first watchpoint, disable all available
watchpoints while clearing dawr_force_enable.

Callback function is used only for disabling watchpoint, rename it
to disable_dawrs_cb(). And null_brk parameter is not really required
while disabling watchpoint, remove it.
