This patch also includes additional changes to allow the code to compile when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of mp_uint_t, and various casts. py: Add MP_ROM_* macros and mp_rom_* types and use them. 2015-11-29T14:25:04+00:00 Damien George damien.p.george@gmail.com 2015-11-27T13:38:15+00:00 urn:sha1:cbf7674025814797f5c537d6d1c195efe58ccaaf extmod/modmachine: Use uintptr_t instead of mp_uint_t for address type. 2015-11-29T14:25:04+00:00 Damien George damien.p.george@gmail.com 2015-11-27T12:46:22+00:00 urn:sha1:278f3592d40ac8826912b6587fe10ee0bc7c49a1 extmod/modmachine: Avoid conflicts with system PAGE_SIZE define, if any. 2015-08-17T21:31:31+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-08-17T21:31:31+00:00 urn:sha1:2a6660ba595bd85a637249cb96a5f451a1aa4034 modmachine: Implement physical memory access using /dev/mem (Linux, etc). 2015-07-08T08:37:23+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-07-05T21:08:33+00:00 urn:sha1:354d17523f599746a84e5b22fa670c9910137947 This requires root access. And on recent Linux kernels, with CONFIG_STRICT_DEVMEM option enabled, only address ranges listed in /proc/iomem can be accessed. The above compiled-time option can be however overriden with boot-time option "iomem=relaxed". This also removed separate read/write paths - there unlikely would be a case when they're different. modmachine: Add new module to access hardware, starting with physical memory. 2015-05-04T10:05:12+00:00 Paul Sokolovsky pfalcon@users.sourceforge.net 2015-05-03T17:25:40+00:00 urn:sha1:0116218fa89cc88d5d5ed7291c4f8d3412f78543 Refactored from "stm" module, provides mem8, mem16, mem32 objects with array subscript syntax.
