[PATCH] the MPU/noMMU support for ARM Linux 2.6.11.6 (-hsc0)
Greetings, I'm glad to announce the MPU and noMMU support patch for ARM against 2.6.11.6 at: http://opensrc.sec.samsung.com/download/linux-2.6.11.6-hsc0.patch.gz Actually the patch was "armnommu" architecture patch by 2.6.9, but it is just merged into "arm" architecture, and provides selection option, "MMU" for linux and "MPU", "NONE" for uclinux. It means that you can choose "MMU" or even "NONE" for your MMU based arm platform with a few modification (i.e. virtual addr --> physical addr), if you want to use "singular address space" which is proven to have performance improvement. (I'd like to provide some benchmark result on same h/w platform for both cases.) some addtional MPU support API is pending to support new features like memory protection for uclinux, but I need more suggestions on that. You can reach the project at : http://opensrc.sec.samsung.com/ currently officially supported platforms are : s3c24a0, s5c7375, atmel, espd_s3c510b, P2001, s3c3410, s3cb0x.

[PATCH] the nommu support for ARM linux 2.6.10
An updated MPU and noMMU support patch for ARM against linux 2.6.10 kernel is available at : http://opensrc.sec.samsung.com/download/linux-2.6.10-hsc1.patch.gz You can select the memory management type "MPU" or "NONE" in the arm kernel configuration menu, which was traditionally known as "armnommu" or uClinux/ARM by 2.6.9. (sure, you can choose "MMU" for vanila Linux :-) It's a different way from other uclinux arch. (i.e. m68knommu), which enables simultaneous support to use "singular address space" support even for MMU platforms. You can choose "MMU" or "NONE" for your mmu based arm platform with a few modification. i.e. virtual address --> physical address conversion. the 2.6.11.6-hsc0 patch will be available in this week, and some benchmark will be provided for both cases on a same h/w platform. and addtional MPU support API is pending for some services like memory protection, even for uClinux. any suggesstions welcomed. You can reach the project home at : http://opensrc.sec.samsung.com/ currently officially supported platforms are : s3c24a0, s5c7375, atmel, espd_s3c510b, P2001, s3c3410, s3cb0x. thanks for contribution : Tobias Lorenz and Jiun-Shian Ho Regards, Hyok --- CHOI, HYOK-SUNG Engineer (Kernel/System Architecture) Digital Media R Center, Samsung Electronics Co.,Ltd. tel: +82-31-200-8594 fax: +82-31-200-3427 e-mail: [EMAIL PROTECTED] [Linux 2.6 ARM MPU/noMMU Kernel Maintainer] http://opensrc.sec.samsung.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

[PATCH] the nommu support for ARM linux 2.6.10
Hi all, I'm glad to release the first MPU and NO-MMU support patch for ARM linux 2.6.10 at : http://opensrc.sec.samsung.com/download/linux-2.6.10-hsc0.patch.gz Previously, it was released as "armnommu" architecture which was called uClinux/ARM and now is merged with "arm" architecture. You can select the memory management type "MMU" for linux and "MPU" / "NONE" for uClinux at the kernel configuration menu. Currently, the ATMEL, S5C7375, S3C24A0 platform is tested. I'm working on 2.6.11.5 patch, and it will be provided soon. It would be great if you give me some suggestions. Best Regards, Hyok HYOK S.
