From 3162534069597e34dd0ac9eb711be8dc23835ae7 Mon Sep 17 00:00:00 2001 From: Joseph Cihula Date: Tue, 30 Jun 2009 19:30:59 -0700 Subject: x86, intel_txt: Intel TXT boot support This patch adds kernel configuration and boot support for Intel Trusted Execution Technology (Intel TXT). Intel's technology for safer computing, Intel Trusted Execution Technology (Intel TXT), defines platform-level enhancements that provide the building blocks for creating trusted platforms. Intel TXT was formerly known by the code name LaGrande Technology (LT). Intel TXT in Brief: o Provides dynamic root of trust for measurement (DRTM) o Data protection in case of improper shutdown o Measurement and verification of launched environment Intel TXT is part of the vPro(TM) brand and is also available some non-vPro systems. It is currently available on desktop systems based on the Q35, X38, Q45, and Q43 Express chipsets (e.g. Dell Optiplex 755, HP dc7800, etc.) and mobile systems based on the GM45, PM45, and GS45 Express chipsets. For more information, see http://www.intel.com/technology/security/. This site also has a link to the Intel TXT MLE Developers Manual, which has been updated for the new released platforms. A much more complete description of how these patches support TXT, how to configure a system for it, etc. is in the Documentation/intel_txt.txt file in this patch. This patch provides the TXT support routines for complete functionality, documentation for TXT support and for the changes to the boot_params structure, and boot detection of a TXT launch. Attempts to shutdown (reboot, Sx) the system will result in platform resets; subsequent patches will support these shutdown modes properly.

The problem is, "reservetop" parameter can modify 'FIXADDR_TOP', then the virtual address got by early_ioremap() is base on old 'FIXADDR_TOP', but the page mapping is base on new 'FIXADDR_TOP', it will occur page fault, and the IDT is not prepare yet, so, the system is dead. So, put parse_early_param() in the front of early_ioremap_init() in this patch.

But the call after parse_early_param() can also not go away, as that will honor eventual command line specified disabling of the NX functionality. ( This will then just result in whatever mappings got established during parse_early_param() having the NX bit set despite it being disabled on the command line, but I think that's tolerable).
