[PATCH 0/2] call32 update
by Kevin O'Connor 25 Nov '10

Fix call32() so that it doesn't require %ss==0, and enable it to pass a parameter. -Kevin Kevin O'Connor (2): Don't pass return address to transition(32,16,16big) on stack. Enhance call32() to pass a parameter to called function. src/entryfuncs.S | 2 +- src/resume.c | 2 +- src/romlayout.S | 14 ++++++++++---- src/stacks.c | 22 +++++++++++----------- src/util.h | 1 + 5 files changed, 24 insertions(+), 17 deletions(-) -- 1.7.3.2

Hi, http://www.seabios.org/pipermail/seabios/2010-March/000396.html Could anyone explain what the difficulty with OHCI bulk in 16-bit mode is before I spend a few hours discovering for myself? Jonathan Kollasch

Either way is fine, but it gives me > direction on how to proceed. I think you should just use call32() and not do anything special. I don't see why you need a function table or any … [View More]

[RFC][PATCH] 0/2: Call 32 bit functions from 16 bit code with parameters
by Stefan Berger 22 Nov '10

22 Nov '10

I am posting the following patches as an RFC. I would want to use them later on for BIOS extensions where work in 32 bit space seems easier to handle due to device addresses and ACPI tables that need to be written into for example being >1M and several function calls invoking functions in 32 bit space from 16 bit space. Parameters to function can be easily passed from 16bit. Also, it doesn't add much code, but provides convenience that others may be able to use as well. It currently … [View More]

[RFC][PATCH 2/2] Add another test function and call tests from 16 bit.
by Stefan Berger 22 Nov '10

22 Nov '10

The following patch adds another test function, 'hello_world' to the 32 bit functions. The intention is to show what needs to be done to support one more function call -- not much. This and the already-existing test function are then called from handle_1a in 16 bit space. After enabling the debugging output, the following then becomes visible: handle_1a at 0x00008356 Calling hello world Hello world at 0x7ffe48f3 test at 0x7ffe4905 a=7,b=8,c=9,d=10,e=11,f=12 Result from upcall res=56 The … [View More]

seabios 0.6.1 regression
by Avi Kivity 16 Nov '10

16 Nov '10

Installing Windows XP with seabios 0.6.1, immediately after the first reboot, Windows hangs in protected mode instead of proceeding with installation. I'm bisecting this, but if anyone can point to a likely culprit, I can try it first. -- error compiling committee.c: too many arguments to function

[PATCH v3 0/2] pciinit: fix overflow when bar allocation
by Isaku Yamahata 13 Nov '10

13 Nov '10

Changes v2 -> v3: - use [first, last] instead of [start, end) Changes v1 -> v2: - add comment. Patch description: This patch set fixes PCI bar allocation when bar overflow occured. I checked if pmm_alloc facility can be used, but it doesn't suit for pci bar allocation. So I resulted in new API, pci_region which encapsulates region allocation and overflow checks. The first patch introduces pci_region, and the second patch fixes the overflow case with pci_region. Isaku Yamahata (2): … [View More]
