| H A D | scanc.c | diff 9485 Tue Jul 11 18:50:47 MDT 1995 bde Rearrange the inner loop of scanc() to get better code on i*86's (on an i486, 10 cycles (+ cache misses) instead of 15). The change should be a no-op if the compiler is any good. The best possible i*86 code for the same algorithm is only 1 more cycle faster on i486's so I don't want to bother implementing an assembler version. scanc() is a bottleneck for OPOST processing. It is naturally about 4 times as slow as bcopy() on 32-bit systems. diff 9485 Tue Jul 11 18:50:47 MDT 1995 bde Rearrange the inner loop of scanc() to get better code on i*86's (on an i486, 10 cycles (+ cache misses) instead of 15).

| H A D | time.c | diff 179825 Mon Jun 16 17:12:19 MDT 2008 olli Implement a workaround for a long-standing problem in libi386's time(), caused by a qemu bug. The bug might be present in other BIOSes, too. qemu either does not simulate the AT RTC correctly or has a broken BIOS 1A/02 implementation, and will return an incorrect value if the RTC is read while it is being updated. The effect is worsened by the fact that qemu's INT 15/86 function ("wait" a.k.a. usleep) is non-implmeneted or broken and returns immediately, causing beastie.4th to spin in a tight loop calling the "read RTC" function millions of times, triggering the problem quickly. Therefore, we keep reading the BIOS value until we get the same result twice. This change fixes beastie.4th's countdown under qemu. Approved by: des (mentor) |

| H A D | btx.S | diff 189017 Tue Feb 24 23:15:08 MST 2009 jhb Fix some more issues with the real mode BTX. The old BTX passed the general purpose registers from the 32-bit client to the routines called via virtual 86 mode. The new BTX did the same thing. However, it turns out that some instructions behave differently in virtual 86 mode and real mode (even though this is under-documented). For example, the LEAVE instruction will cause an exception in real mode if any of the upper 16-bits of %ebp are non-zero after it executes. In virtual 8086 mode the upper 16-bits are simply ignored. This could cause faults in hardware interrupt handlers that inherited an %ebp larger than 0xffff from the 32-bit client (loader, boot2, etc.) while running in real mode. To fix, when executing hardware interrupt handlers provide an explicit clean state where all the general purpose and segment registers are zero upon entry to the interrupt handler. While here, I attempted to simplify the control flow in the 'intusr' code that sets up the various stack frames and exits protected mode to invoke the requested routine via real mode. A huge thanks to Tor Egge (tegge@) for debugging this issue.

This allows the 8259As to use vectors 0x20-0x2f in real mode as well as protected mode will ensuring that the master 8259A doesn't share IDT space with CPU exceptions in protected mode. - Since we don't need to reserve space for page tables and a page directory anymore since dropping paging support, move the TSS and protected mode IDT up by 16k. Grow the ring 1 link stack by 16k as a result. - Repurpose the ring 1 link stack to be used as a real mode stack when invoking real mode routines either via a V86 request or a hardware interrupts. This simplifies a few things as we avoid disturbing the original user stack. - Add some more block comments to explain how the code interacts with the V86 structure as this wasn't immediately obvious from the prior comments (e.g. that we explicitly copy the seg regs for real mode out of the V86 struct onto the stack to be popped off when going into real mode, etc.). Also, document some of the stack frames we create going to real mode and back. - Remove all of the virtual 86 related code including having to simulate various instructions and BIOS calls on a trap from virtual 86 mode. - Explicitly panic if a user client attempts to perform a V86 CALL request that isn't a far call. - Bump version to 1.2. Assuming this works ok this should fix some of the long standing issues with USB booting as well as etherboot.
