Hi Marek, With v19, I can't seem to allocate big regions anymore (e.g. 101MiB). In particular, this seems to fail: On Thu, Jan 26, 2012 at 11:00 AM, Marek Szyprowski <m.szyprowski@xxxxxxxxxxx> wrote: > +static int cma_activate_area(unsigned long base_pfn, unsigned long count) > +{ > + unsigned long pfn = base_pfn; > + unsigned i = count >> pageblock_order; > + struct zone *zone; > + > + WARN_ON_ONCE(!pfn_valid(pfn)); > + zone = page_zone(pfn_to_page(pfn)); > + > + do { > + unsigned j; > + base_pfn = pfn; > + for (j = pageblock_nr_pages; j; --j, pfn++) { > + WARN_ON_ONCE(!pfn_valid(pfn)); > + if (page_zone(pfn_to_page(pfn)) != zone) > + return -EINVAL; The above WARN_ON_ONCE is triggered, and then the conditional is asserted (page_zone() retuns a "Movable" zone, whereas zone is "Normal") and the function fails. This happens to me on OMAP4 with your 3.3-rc1-cma-v19 branch (and a bunch of remoteproc/rpmsg patches). Do big allocations work for you ?
