* ide: convert ide_hwif_t.mmio into flag (v2)Bartlomiej Zolnierkiewicz2007-02-16
| | | | | | | | | | | | All users of ->mmio == 1 are gone so convert ->mmio into flag. Noticed by Alan Cox. v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
* ide: use PIO/MMIO operations directly where possible (v2)Bartlomiej Zolnierkiewicz2007-02-16
| | | | | | | | | | | This results in smaller/faster/simpler code and allows future optimizations. Also remove no longer needed ide[_mm]_{inl,outl}() and ide_hwif_t.{INL,OUTL}. v2: * updated for scc_pata Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * add ide_use_fast_pio() helper for use by host drivers * add DMA capability and hwif->autodma checks to ide_use_dma() - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1) [ for the IT8211/2 in SMART mode this check shouldn't be made but since in it821x_fixups() we set DMA bit explicitly: if(strstr(id->model, "Integrated Technology Express")) { /* In raid mode the ident block is slightly buggy We need to set the bits so that the IDE layer knows LBA28. LBA48 and DMA ar valid */ id->capability |= 3; /* LBA28, DMA */ we are better off using generic helper if we can ] - ide-cris driver didn't set ->autodma [ before the patch hwif->autodma was only checked in the chipset specific hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check() function so there no behavior change here ] v2: * updated patch description (thanks to Alan Cox for the feedback) v3: * updated for scc_pata driver Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* drivers/ide: PATA driver for CellebKou Ishizaki2007-02-16
| | | | | | | | | | | | | | | | | | | | | | This is the patch (based on 2.6.19-rc4) for PATA controller of Toshiba Cell reference set(Celleb). The reference set consists of Cell, 512MB memory, Super Companion Chip(SCC) and some peripherals such as HDD, GbE, etc. You can see brief explanation and picture of Cell reference set at following URLs. http://www.toshiba.co.jp/about/press/2005_09/pr2001.htm http://cell-industries.com/toshiba_announces.php We use a drivers/ide driver because its design is more suitable for SCC IDE controller than libata driver. Since SCC supports only 32bit read/write, we must override many callbacks of ata_port_operations by modifying generic helpers. Each time the libata common code is updated, we must update those modified helpers. It is very hard for us. But we will try to implement the libata driver as needed.

* sl82c105: DMA support fixesSergei Shtylyov2007-02-16
| | | | | | | | | | | | | | | | | | | | | Fix a number of issues with the DMA support code: - driver claims support for all SW/MW DMA modes while supporting only MWDMA2; - ide_dma_check() method tries to enable DMA on the "known good" drives which don't support MWDMA2; - ide_dma_on() method upon failure to set drive to MWDMA2 re-tunes already tuned PIO mode and calls ide_dma_off() method instead of returning error; - ide_dma_off() method sets drive->current_speed while it doesn't actually change (only the PIO timings are re-loaded into the chip's registers); - init_hwif() method forcibly sets/resets both "drive DMA capable" bits while this is properly handled by ide_dma_{on,off}() methods being called later...

* ide-floppy: Fix unformatted media crashAlan Cox2007-02-16
| | | | | | | | | | | | | | | | | A ZIP or similar with unformatted media will cause crashes when attempts are made to read/write it in some cases. This is because bs_factor is zero and we divide by it causing an oops. As the size of a non-accessible/non-existant media is really a bit of a zen question it doesn't matter if non-existant media is 512 bytes per sector or zero. Setting it to 1 causes us to generate 512 bytes/sector accesses and error properly.

In such scenario ide_dma_enable() will incorrectly return true statement and ->ide_dma_check will try to enable DMA on the device. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows drm to populate an agpgart structure with pages of its own. It's needed for the new drm memory manager which dynamically flips pages in and out of AGP. The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is currently the only one supporting the new memory manager. Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver. AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected to do that, as well as taking care of cache- and tlb flushing when needed. It's not possible to request these types from user space using agpgart ioctls. The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

It provides voltage scaling and can use ACPI C3 state. That's curious. CPU will not change frequency on ACPI C3 when v1 is in use, but it will when v2 is used. Driver will return max frequency all the time if this isn't true for all processors. There is strange thing with mobile voltage. Looks like only Nehemiah (C3-M) supports it. Earlier processors have different mobile VRM (in docs), but I can't find any which is using it. Looks like all are using VRM 8.5. So fail for non Nehemiah with mobile VRM.

Using flush there has a deadlock potential as in http://uwsg.iu.edu/hypermail/linux/kernel/0611.3/1223.html Also, cleanup the locking issues with do_dbs_timer delayed_work callback. As it changes the CPU frequency using __cpufreq_target, it needs to have policy_rwsem in write mode, which also protects it from hot plug.
