* Keep DMA enabled on QEMU disksSamuel Thibault2018-06-131-0/+8
| | | | | | | | When the host is very loaded, some requests might time out, but that is not a reason for disabling DMA, so keep it enabled. * linux/src/drivers/block/triton.c (config_drive_for_dma): When disk is QEMU, set using_dma and keep_settings to 1.
* linux block: fix outbound access to non-directmap user dataSamuel Thibault2017-11-011-4/+6
| | | | | * linux/dev/glue/block.c (rdwr_full): Set BH_Bounce if the physical address of the user data is not in directmap.
* linux-block: Fix calling vm_map_copy_discard on uninitialized variableSamuel Thibault2017-10-311-2/+1
| | | | | | | | | This happens if passed count is 0. Reported by Richard Braun. * linux/dev/glue/block.c (device_write): Set copy variable before vm_map_copy_discard() is called.
* linux: Fix warnings.Justus Winter2017-10-261-2/+1
| | | | * linux/dev/glue/net.c (device_write): Remove unused variables.
* linux: Fix interrupt glue.Justus Winter2017-09-301-2/+16
| | | | | | | | | | | Previously, we used an invalid pointer to mark interrupts as reserved by Mach. This, however, crashes code trying to iterate over the list of interrupt handlers. Use a valid structure instead. * linux/dev/arch/i386/kernel/irq.c (reserved_mach_handler): New function. (reserved_mach): New variable. (reserve_mach_irqs): Use the new variable.
* Support GCC 7David Michael2017-05-071-0/+67

* kern: Improve assertions and panics.Justus Winter2016-10-011-2/+4
| | | | | | | | | | * kern/assert.h (Assert): Add function argument. (assert): Supply function argument. * kern/debug.c (Assert): Add function argument. Unify message format. (panic): Rename to 'Panic', add location information. * kern/debug.h (panic): Rename, and add a macro version that supplies the location. * linux/dev/include/linux/kernel.h: Use the new panic macro.

* Update Linux block layer glue codeRichard Braun2016-09-211-15/+16
| | | | | | | | | | The Linux block layer glue code needs to use page nodes with the appropriate interface since their redefinition as struct list. * linux/dev/glue/block.c: Include <kern/list.h>. (struct temp_data): Define member `pages' as a struct list. (alloc_buffer): Update to use list_xxx functions. (free_buffer, INIT_DATA, device_open, device_read): Likewise.
* Redefine what an external page isRichard Braun2016-09-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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". This commit mostly deals with the impact of this change on the page allocation interface. * i386/intel/pmap.c (pmap_page_table_page_alloc): Update call to vm_page_grab. * kern/slab.c (kmem_pagealloc_physmem): Use vm_page_grab instead of vm_page_grab_contig.

* Remove phys_first_addr and phys_last_addr global variablesRichard Braun2016-09-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old assumption that all physical memory is directly mapped in kernel space is about to go away. Those variables are directly linked to that assumption. * i386/i386/model_dep.h (phys_first_addr): Remove extern declaration. (phys_last_addr): Likewise. * i386/i386/phys.c (pmap_zero_page): Use VM_PAGE_DIRECTMAP_LIMIT instead of phys_last_addr.

(phys_last_addr): Likewise. (pmap_free_pages, pmap_valid_page): Remove functions. * i386/intel/pmap.c: Include i386at/biosmem.h. (pa_index): Turn into an alias for vm_page_table_index.

(valid_page): Turn this macro into an inline function and rewrite using vm_page_lookup_pa. (pmap_page_table_page_alloc): Build the pmap VM object using vm_page_table_size to determine its size. (pmap_remove_range, pmap_page_protect, phys_attribute_clear, phys_attribute_test): Turn page indexes into unsigned long integers. (pmap_enter): Likewise. In addition, use either vm_page_lookup_pa or biosmem_directmap_end to determine if a physical address references physical memory. * i386/xen/xen.c (hyp_p2m_init): Use vm_page_table_size instead of phys_last_addr to obtain the number of physical pages. * kern/startup.c (phys_first_addr): Remove extern declaration. (phys_last_addr): Likewise. * linux/dev/init/main.c (linux_init): Use vm_page_seg_end with the appropriate segment selector instead of phys_last_addr to determine where high memory starts. * vm/pmap.h: Update requirements description.

(vm_page_bootstrap): Compute VP table size based on the page table size instead of the value returned by pmap_free_pages.

* Fallback on direct PCI access when no BIOS32 is availableSamuel Thibault2016-01-291-0/+2
| | | | | | | | | Some hardware start shippping with no BIOS32 at all, and we'll have to implement ACPI to get the address of the mmconfig table. In the meanwhile, we can hope that the direct probe works (it does on HP820 for instance). * linux/src/arch/i386/kernel/bios32.c (pcibios_init): Also try check_direct_pci() when bios32 probing failed.
* Use vm_page as the physical memory allocatorRichard Braun2016-01-234-143/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change replaces the historical page allocator with a buddy allocator implemented in vm/vm_page.c. This allocator allows easy contiguous allocations and also manages memory inside segments. In a future change, these segments will be used to service requests with special constraints, such as "usable for 16-bits DMA" or "must be part of the direct physical mapping". * Makefrag.am (libkernel_a_SOURCES): Add vm/vm_page.c. * i386/Makefrag.am (libkernel_a_SOURCES): Add i386/i386at/biosmem.{c,h}. * i386/i386/vm_param.h: Include kern/macros.h.
