Remove the freelist member from vm_physseg 2011-05-30T22:25:20Z oga oga@openbsd.org 2011-05-30T22:25:20Z urn:sha1:2ce3b4a8d453aa5b9e1d594f23fa8cfc79a224b6 The new world order of pmemrange makes this data completely redundant (being dealt with by the pmemrange constraints instead). Remove all code that messes with the freelist. While touching every caller of uvm_page_physload() anyway, add the flags argument to all callers (all but one is 0 and that one already used PHYSLOAD_DEVICE) and remove the macro magic to allow callers to continue without it. Should shrink the code a bit, as well. matthew@ pointed out some mistakes i'd made. ``freelist death, I like. Ok.' ariane@ `I agree with the general direction, go ahead and i'll fix any fallout shortly'' miod@ (68k 88k and vax i could not check would build) Normalize sentinel. Use _MACHINE_*_H_ and _<ARCH>_*_H_ properly and consitently. 2011-03-23T16:54:33Z pirofti pirofti@openbsd.org 2011-03-23T16:54:33Z urn:sha1:2fa72412907ae78c4787a4a8f888c5f0486e225c Discussed and okay drahn@. Okay deraadt@. Unconditionnaly move kernel virtual memory space to XKSEG, now that previous 2009-12-08T22:15:47Z miod miod@openbsd.org 2009-12-08T22:15:47Z urn:sha1:84d051cf4f68d22779d3057001e2f6fc53eda914 context.S fixes allows these settings to work for kernels linked in CKSEG0. grammar fixes in comments; from brad 2009-11-22T10:05:02Z miod miod@openbsd.org 2009-11-22T10:05:02Z urn:sha1:0a08696c131455e6947bd4ca60e835b8af722550 Allow mips ports to override VM_{MIN,MAX}_KERNEL_ADDRESS, and provide the 2009-11-22T00:07:02Z miod miod@openbsd.org 2009-11-22T00:07:02Z urn:sha1:8608c891a3e97bb12beeb2ce291fd3fd59d9a3c0 address as a kernel variable for use by libkvm. On sgi IP27 and IP30 kernels, use XKSEG instead of CKSSEG; this will allow kernel KVM size to grow in the future if necessary. Add some comments to explain why the DMA32 physseg is really 2**31 bytes 2009-10-14T20:18:26Z miod miod@openbsd.org 2009-10-14T20:18:26Z urn:sha1:bca357705698462c58c3d6eeb2c616037e0cdd0e long. Prompted by deraadt@ long ago. Add a new page freelist, to which memory suitable for 32-bit dma on 2009-05-08T18:42:04Z miod miod@openbsd.org 2009-05-08T18:42:04Z urn:sha1:2c4cd64477964a3b604ec7d69aee6118528d67e1 xbridge(4) is assigned. Then, make bus_dmamem_alloc() allocate from this range only. This is transparent on O2, and makes sure the bus_dma memory address will fit in the 2GB direct map of xbridge(4) chips - this is necessary for PCI devices which do not handle 64 bit dma addresses. Allow for up to 32 memory segments. 2008-04-07T22:41:52Z miod miod@openbsd.org 2008-04-07T22:41:52Z urn:sha1:83ba6cc315819fa644808dc4b6dda60183e80857 initial sgi import 2004-08-06T21:12:18Z pefo pefo@openbsd.org 2004-08-06T21:12:18Z urn:sha1:20fc814e6ef83a91b61bae20069de95193d31dff
