Michael Brown	6abfaa153b	Towards making KEEP_IT_REAL work again. Fix bug that caused over-allocation of .text16 and .data16 memory areas by a factor of 16.	18 년 전
Michael Brown	35b04b1514	Tidy up comment	18 년 전
Michael Brown	041a04335e	Fixed assembly on old versions of gas	18 년 전
Michael Brown	29340d7728	Documented the fact that the prefix can prot_call(main) without worrying about its stack being destroyed during the Etherboot run.	18 년 전
Michael Brown	89da833c5d	init_librm() and prot_call() are now real-mode far calls. install() now calls relocate(), moves the protected-mode code to the new location, and calls hide_etherboot().	18 년 전
Michael Brown	02cf755f3f	Removed REAL_EXEC(); there is no longer any code using it.	18 년 전
Michael Brown	83d80d9e79	Remove references to obsoleted REAL_CALL from documentation.	18 년 전
Michael Brown	5080668704	Provide access to rm_cs and rm_ds from protected-mode code.	18 년 전
Michael Brown	f7b963da51	(Redoing check-in lost by SourceForge's failure.) Use .text16.data section with "aw" attributes, to avoid section type conflicts when placing both code and data into .text16. Add __from_{text16,data16}.	18 년 전
Michael Brown	fdb983d473	Preserve the whole of %esp across prot_call(). We have to split this between the low half stored in the static variable rm_sp, and the high half stored on the prot_call() stack, because: Just using the stack would screw up when a prot_call()ed routine executes a real_call(); it would have no way to find the current top of the RM stack. Extending rm_sp to rm_esp would not be safe, because the guarantee that rm_sp must return to the correct value by the time an external real-mode call returns applies only to %sp, not to %esp.	18 년 전
Michael Brown	c10d1aa9d7	Preserve GDT across prot_call().	18 년 전
Michael Brown	dcc1b0054e	This line should not have been checked in	18 년 전
Michael Brown	832807726a	Add infrastructure to support access to .data16 (and .text16) variables from protected-mode code. Set up %ds to point to .data16 in prot_to_real, so that code specified via REAL_EXEC() and friends can access variables in .data16. Move most real-mode librm variables from .text16 to .data16.	18 년 전
Michael Brown	10c28a51bd	Create two easy-to-use entry points in libprefix: install and install_prealloc. I think these will suffice for all the 16-bit prefixes.	18 년 전
Michael Brown	9fcded3d23	Towards a(nother) new real-mode infrastructure, in which we take advantage of the fact that we have to have a permanently-resident block in base memory.	18 년 전
Michael Brown	352bf1bda2	Move init.h to gpxe/init.h.	18 년 전
Michael Brown	4c4e4de18f	(librm_base-1b) is already an offset; no need to apply OFFSET(). Doing so, in fact, seems to expose an assembler bug; (a-b-0) is apparently not the same as (a-b). Go figure.	18 년 전
Michael Brown	d3dec7c331	Update to cope with changes in registers.h	19 년 전
Michael Brown	378c1b500c	Cleaner separation of functionality between post_reloc and initialise_via_librm.	19 년 전
Michael Brown	34a0b5f16f	initialise() doesn't take regs	19 년 전
Michael Brown	87508aa0b2	arch_initialise() is now sufficiently generic that we may as well just call it initialise() and place it in main.c. :)	19 년 전
Michael Brown	560027899e	Heading towards a sane set of control functions	19 년 전
Michael Brown	04a99841e6	Make prot_call() able to transparently return via the newly installed copy of librm.	19 년 전
Michael Brown	2fa14f2f1d	lgdt needs data32 prefix, otherwise it loads only 24 bits. (sgdt always saves 32 bits).	19 년 전
Michael Brown	6a4ac358f3	Add INIT_FNs to make sure that librm gets reallocated when needed.	19 년 전
Michael Brown	1f6dfd7047	Allow ourselves to be freed by basemem.c without being damaged.	19 년 전
Michael Brown	a800e9657d	PM function called by prot_call() should be allowed to modifying registers returned to RM code.	19 년 전
Michael Brown	0ff80b477d	Merged mcb30-realmode-redesign back to HEAD	19 년 전
