Hi,<br>
<br>
without testing your code, I guess increasing the size of the mapping
metadata could help.<br>
In pmap_target.c:37:<br>
#define META_DATA_RESERVED_SIZE (X86_64_BASE_PAGE_SIZE * 20000)<br>
<br>
Greetings,<br>

<pre wrap="">Hello,
SharedDB requires large chunks of memory to store its data [*]. I ran into
problems allocating 1 GB with malloc() and switched to frame_alloc(). That
initially seemed to solve the issue, but unfortunately also fails. Allocating
an 8 GB frame succeeds, but mapping it fails:
[BEFORE] System memory: free: 135958609920 bytes, total: 137277911040 bytes
Allocated frame of 8589934592 bytes.
assertion "pmap->vregion_offset < vregion_get_base_addr(&pmap->vregion) + vregion_get_size(&pmap->vregion)" failed: file "../lib/barrelfish/target/x86_64/pmap_target.c", line 319, function: refill_slabs
Aborted
Attached is a minimal example which demonstrates the problem. Any ideas?
Best,
--Zaheer
[*] When running TPC-W on Linux, tcmalloc reports total memory usage as 10.2 GB.
On IRC I mentioned a figure of 2.7 GB, but that appears incorrect as Massif
doesn't seem to have accounted for everything.
