This patch changes the segment descriptors to Big Real Mode instead. The segment descriptor registers (what Intel calls "segment cache") is always active. The only thing that changes based on CR0.PE is how it is *loaded* and the interpretation of the CS flags. The segment descriptor registers contain of the following sub-registers: selector (the "visible" part), base, limit and flags. In protected mode or long mode, they are loaded from descriptors (or fs.base or gs.base can be manipulated directly in long mode.) In real mode, the only thing changed by a segment register load is the selector and the base, where the base <- selector << 4. In particular, *the limit and the flags are not changed*. As far as the handling of the CS flags: a code segment cannot be writable in protected mode, whereas it is "just another segment" in real mode, so there is some kind of quirk that kicks in for this when CR0.PE <- 0. I'm not sure if this is accomplished by actually changing the cs.flags register or just changing the interpretation; it might be something that is CPU-specific. In particular, the Transmeta CPUs had an explicit "CS is writable if you're in real mode" override, so even if you had loaded CS with an execute-only segment it'd be writable (but not readable!) on return to real mode. I'm not at all sure if that is how other CPUs behave. Signed-off-by: "H. Peter Anvin" <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* | / / x86 ACPI: normalize segment descriptor register on resumeH. Peter Anvin2008-07-05

The only way to clean that up is to enter protected mode ourselves and clean out the descriptor registers. This fixes resume on Dell XPS M1210 and Dell D620.

The root of the tree is the RSDP (Root System Description Pointer). To find the RSDP, the OS searches for the signature "RSD PTR " in well known physical memory locations. Then the OS computes a table checksum to verify that the signature is really part of a valid table header. Some systems have a proper signature but an invalid checksum; followed elsewhere by a proper signature with valid checksum. http://bugzilla.kernel.org/show_bug.cgi?id=9444 The Linux RSDP scanning code bailed out on those systems and as a result they booted with ACPI disabled. Fix this by deleting the Linux RSDP scanning code and plugging in the ACPICA RSDP scanning code. Signed-off-by: Len Brown <len.brown@intel.com>

* | | | x86: rename the struct pt_regs members for 32/64-bit consistencyH. Peter Anvin2008-01-30
| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a lot of code which differs only by the naming of specific members of structures that contain registers. In order to enable additional unifications, this patch drops the e- or r- size prefix from the register names in struct pt_regs, and drops the x- prefixes for segment registers on the 32-bit side. This patch also performs the equivalent renames in some additional places that might be candidates for unification in the future. Signed-off-by: H.

|/ | | | | | | | | | | | Some BIOSes advertise HPET at 0x0. We really do no want to allocate a resource there. Check for it and leave early. Other BIOSes tell us the HPET is at 0xfed0000000000000 instead of 0xfed00000. Add a check and fix it up with a warning on user request. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
