[PATCH 0/3] x86: remove x86_init.mapping.pagetable_reserve

[PATCH 0/3] x86: remove x86_init.mapping.pagetable_reserve

[Stefano Stabellini]

Currently find_early_table_space calculates an overestimate of how much
memory the pagetable for 1:1 mapping is going to need. After
kernel_physical_mapping_init completes we know exactly how much memory
we used so we memblock reserve only the used memory and "free" the rest.

This patch series modifies find_early_table_space to calculate the exact
amount of memory we need for the 1:1 mapping, so that we can memblock
reverve it right away and we don't need to free the unused memory after
kernel_physical_mapping_init.

At this point we can also safely revert "x86,xen: introduce
x86_init.mapping.pagetable_reserve".


The list of patches with diffstat follows:

[PATCH 1/3] x86: calculate precisely the memory needed by init_memory_mapping

[stefano.stabellini]

From: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

- take into account the size of the initial pagetable;

- remove the extra PMD_SIZE added when use_pse, because the previously
allocated PMDs are always 2M aligned;

- remove the extra page added on x86_32 for the fixmap because is not
needed: the PMD entry is already allocated and contiguous for the whole
range (a PMD page covers 4G of virtual addresses) and the pte entry is
already allocated by early_ioremap_init.

If (due to a bug) pgt_buf_end > pgt_buf_top, this will printk a
message about wasting a negative number of pages, rather than
crashing.  Is there something else that will catch this case ?

Thanks for reviewing this patch!

Yes, there is something else that catches this case: both the 32 bit
and the 64 bit versions of alloc_low_page contain this code:


unsigned long pfn = pgt_buf_end++;

if (pfn >= pgt_buf_top)
		panic("alloc_low_page: ran out of memory");


so we are safe from that point of view.

Hi Stefano,

I think this is wrong.  A PMD page covers *1G* of virtual addresses, and
in the 2+2 and 1+3 memory configurations, we may or may not need a
separate PMD for the fixmap.

Am I missing something?

You are right, a PMD page covers 1G of virtual addresses so that part of
the explanation in the comment is wrong.

The reason why we don't need a separate PMD for the fixmap is that in
both PAE and non-PAE cases the last gigabyte of virtual addresses is
always covered by the initial allocation in head_32.S (swapper_pg_dir or
initial_pg_pmd).

Ok, wasn't sure if Xen used the static allocation or not.

x86, mm: Calculate precisely the memory needed by init_memory_mapping

- take into account the size of the initial pagetable;

- remove the extra PMD_SIZE added when use_pse, because the previously
  allocated PMDs are always 2M aligned;

- remove the extra page added on x86_32 for the fixmap because is not
  needed: we allocate all possible PMDs statically in init_32.S and
  the pte entry is already allocated by early_ioremap_init.

x86, init : Move memblock_x86_reserve_range PGTABLE to find_early_table_space

Now that find_early_table_space knows how to calculate the exact amout
of memory needed by the kernel pagetable, we can reserve the range
directly in find_early_table_space.

This allows Xen to know what memory range these will occupy and
therefore how to manage that memory.

Thanks for the logs; I was able to reproduce the problem and I know what
the issue is: CONFIG_DEBUG_PAGEALLOC forces use_pse to 0 while
on x86_64 cpu_has_pse is 1.
As a consequence the initial pagetable allocator in head_64.S didn't
allocate any pte pages but find_early_table_space assumes it did.
The issue doesn't happen on x86_32 (PAE and non-PAE) because head_32.S
always uses 4KB pages.

The patch below fixes the problem: on x86_64 we should not limit the
memory size we need to cover with 4KB ptes depending on the initial
allocation, because head_64.S always uses 2MB pages.

Ingo, if you know any other debug config options that might affect
page table allocations, please let me know.

commit 2b66a94cf8dbbf4cf2148456381b8674ed8191f0
Author: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
Date:   Wed Jun 22 11:46:23 2011 +0000

    x86_64: do not assume head_64.S used 4KB pages when !use_pse
    
    head_64.S, which sets up the initial page table on x86_64, is not aware
    of PSE being enabled or disabled and it always allocates the initial
    mapping using 2MB pages.
    
    Therefore on x86_64 find_early_table_space shouldn't update the amount
    of pages needed for pte pages depending on the size of the initial
    mapping, because we know for sure that no pte pages have been allocated
    yet.
