* linux block: allow loading data up to 4GiB limitSamuel Thibault2021-08-281-1/+8
| | | | | | | | | | | | | | Linux drivers are only limited by the DMA32 constraint, not by the directmap constraint. But our segment order is currently set to DMA < DMA32 < DIRECTMAP < HIGHMEM (since that is what we will have in 64bit mode). In PAE mode this makes DMA32 limited to 800MiB. Ideally we'd have DMA < DIRECTMAP < DMA32 < HIGHMEM but that'd make the memory code more complex, and we are to remove the Linux drivers anyway. In the meanwhile, In non-PAE mode we can just use HIGHMEM which is already limited to 4GiB, that will do the work. * linux/dev/glue/block.c (VM_PAGE_LINUX): New macro. (device_read): Use VM_PAGE_LINUX instead of VM_PAGE_DMA32.
* linux block: Fix checking block sector.Samuel Thibault2021-08-271-0/+2

* vm_page_grab: allow allocating in high memorySamuel Thibault2021-08-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | vm_page_grab was systematically using the VM_PAGE_SEL_DIRECTMAP selector to play safe with existing code. This adds a flags parameter to let callers of vm_page_grab specify their constraints. Linux drivers need 32bit dmas, Xen drivers use kvtophys to clear some data. Callers of kmem_pagealloc_physmem and vm_page_grab_phys_addr also use kvtophys. Otherwise allocations can go to highmem. This fixes the allocation jam in the directmap segment. * vm/vm_page.h (VM_PAGE_DMA, VM_PAGE_DMA32, VM_PAGE_DIRECTMAP, VM_PAGE_HIGHMEM): New macros. (vm_page_grab): Add flags parameter. * vm/vm_resident.c (vm_page_grab): Choose allocation selector according to flags parameter. (vm_page_convert, vm_page_alloc): Pass VM_PAGE_HIGHMEM to vm_page_grab.

* Update Linux block layer glue codeRichard Braun2016-09-211-15/+16

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of a "page considered external", which apparently takes into account whether a page is dirty or not, redefine this property to reliably mean "is in an external object".
