* Export the 64-bit partition offset and use it in chain.cH. Peter Anvin2010-06-271-0/+2
| | | | | | | | | | | | | When used with the "fs" option to chain.c32, we need to know our own filesystem offset. That means knowing if we used the MBR vs GPT partition information, as well as if we ended up using the passed-in information or not. Resolve this by providing an explicit pointer to the current partition offset. Eventually this should be replaced by some kind of statfs() call. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* PM getcwd(); Fix COM32 getcwdGene Cumm2010-06-261-0/+1
| | | | | | | | | Implement getcwd() in the core; Fix COM32 getcwd() to use the new function. This resolves the previous comment about COM32 getcwd() not working by not using INT 22h AX=001Fh. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* Fix COM32 chdir()Gene Cumm2010-06-261-0/+2

* pxe: centralize all the IP information and export it to modulesH. Peter Anvin2010-06-181-0/+9
| | | | | | | | | It appears that there still are PXE stacks in the field which needs the crutch of being pointed to the default gateway. As such, put all the IP information into a single memory structure and allow modules to see it. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

* core: move idle handling into protected modeH. Peter Anvin2010-03-303-1/+8
| | | | | | | | Do the actual idling in protected mode. This both allows PM code a more efficient interface, but also handles bugs in HVM implementations which don't handle HLT in real mode. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>

| | | | | | | | | | | | | | | | The 16-bit API to opendir/readdir/closedir was confused, had a memory leak, and was incompatible with Syslinux 3.x anyway. Replace it with a pure 32-bit API. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

* | core: use better malloc; add low memory malloc; fix com32 exitH. Peter Anvin2010-02-231-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Use a better malloc for the core. In particular, use the same core that we should eventually be able to use for the entire system in Syslinux 5 -- with module awareness, etc. This code can also accommodate multiple heaps. Set up a separate heap for lowmem; the intent is to use explicit lowmem allocations instead of the static bounce buffer. The lowmem allocation is also exported via the pmapi mechanism, so modules can safely allocate lowmem. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | | | | | | | Don't display the cursor on the graphical screen while doing a quiet boot. When doing a quiet boot we will probably show the graphical screen for a fair bit of time; as a result, we really don't want a completely bogus cursor blob on the bottom of the screen.

| | | | | | | | | | | | | | | | | | | | | | | | Fix an uninitialized pointer bug; return void rather than returning int like normal printfs... if we're depending on the return value of a debugging function we're screwed when debugging is disabled. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| * | libansi: reset SGR parameters cache in cls()Pierre-Alexandre Meyer2009-11-021-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was a bug in HDT when switching from the menu to the cli and back to the menu: the background wasn't redrawn. This was due to the fact that the cli bypasses the libansi library and calls printf() directly. Unfortunately, the SGR attributes were cached between menu initializations and the background wasn't properly redrawn. To fix it, invalidate the cache in the cls() routine. cls() does much more than just erasing the screen already (e.g. initialize G1) - we may want to rename the function at some point.
