From 18801be7f805b891876a6676ec7fac2e1acdec13 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Thu, 25 Dec 2008 18:17:09 +0900 Subject: sh: make gpio_get/set_value() O(1) This patch modifies the table based SuperH gpio implementation to make use of direct table lookups. With this change the functions gpio_get_value() and gpio_set_value() are O(1). Tested on Migo-R using bitbanging mmc. Performance is improved from 11 KBytes/s to 26 Kbytes/s.

Both 16-bit and 32-bit CMT versions are supported, but only 32-bit is tested. This driver contains support for both clockevents and clocksources, but no unregistration is supported at this point. Works fine as clock source and/or event in periodic or oneshot mode. Tested on sh7722 and sh7723, but should work with any cpu/architecture. This version is lacking clocksource and early platform driver support for now - this to minimize the amount of dependencies.

This patch updates the maple bus to support asynchronous block reads and writes as well as generally improving the quality of the code and supporting concurrency (all needed to support the Dreamcast visual memory unit - a driver will also be posted for that). Changes in the bus driver necessitate some changes in the two maple bus input drivers that are currently in mainline. As well as supporting block reads and writes this code clean up removes some poor handling of locks, uses an atomic status variable to serialise access to devices and more robusly handles the general performance problems of the bus.

This helps processors such as sh7750, sh7780 and sh7785 which have more vectors than masking ability. With this patch in place we can modify the intc tables to use one irq per maskable irq source. Please note the following: - If multiple vectors share the same enum then only the first vector will be available as a linux irq. - Drivers may need to be rewritten to get pending irq source from the hardware block instead of irq number. This patch together with the sh7785 specific intc tables solves DMA controller irq issues related to buggy interrupt masking.

To suspend, use "swapon /dev/sda2; echo disk > /sys/power/state" To resume, pass "resume=/dev/sda2" on the kernel command line. The patch "pm: rework includes, remove arch ifdefs V2" is needed to allow the generic swsusp code to build properly. Hibernation is not enabled with this patch though, a patch setting ARCH_HIBERNATION_POSSIBLE will be submitted later.

This patch adds support for the Sega Dreamcast visual memory unit as a flash mapping. It requires changes in the maple bus driver (posted separately) to support block reads and writes. The VMU is a 'smart' flash device, with a built-in 8-bit controller - for instance there is an erase before a write but it is hidden from the user. But the device's overall behaviour means it works well with the mtd layer and it is appropriate to add it as an mtd mapping.

We simply stop hardware on suspend and start it again on resume. For RGB panels this is trivial, but for SYS panels in deferred io mode this becomes a bit more difficult - we need to wait for a frame end interrupt to make sure the clocks are balanced before stopping the actual hardware.

This adds support for extended ASIDs (up to 16-bits) on newer SH-X3 cores that implement the PTAEX register and respective functionality. Presently only the 65nm SH7786 (90nm only supports legacy 8-bit ASIDs). The main change is in how the PTE is written out when loading the entry in to the TLB, as well as in how the TLB entry is selectively flushed. While SH-X2 extended mode splits out the memory-mapped U and I-TLB data arrays for extra bits, extended ASID mode splits out the address arrays. While we don't use the memory-mapped data array access, the address array accesses are necessary for selective TLB flushes, so these are implemented newly and replace the generic SH-4 implementation. With this, TLB flushes in switch_mm() are almost non-existent on newer parts.

This follows the ARM change from Aaro Koskinen: When unmapping N pages (e.g. shared memory) the amount of TLB flushes done can be (N*PAGE_SIZE/ZAP_BLOCK_SIZE)*N although it should be N at maximum. With PREEMPT kernel ZAP_BLOCK_SIZE is 8 pages, so there is a noticeable performance penalty when unmapping a large VMA and the system is spending its time in flush_tlb_range(). The problem is that tlb_end_vma() is always flushing the full VMA range. The subrange that needs to be flushed can be calculated by tlb_remove_tlb_entry(). This approach was suggested by Hugh Dickins, and is also used by other arches. The speed increase is roughly 3x for 8M mappings and for larger mappings even more. Bits and peices are taken from the ARM patch as well as the existing arch/um implementation that is quite similar. The end result is a significant reduction in both partial and full TLB flushes initiated through flush_tlb_range(). At the same time, the nommu implementation was broken, had a superfluous cache flush, and subsequently would have triggered a BUG_ON() if a code-path had triggered it. Tidy this up for correctness and provide a nopped-out implementation there.
