This case is to add more exported interfaces to PSARC 2004/151 for the AGPgart driver. The requested release binding is patch/micro. I have marked it as "closed approved automatic" since the change is straightforward and the interface is clear. If there is request, I'd be happy to upgrade it to a fast track and set the timer. -Frank 4. Technical Description 4.1 Summary This project is to add more IOCTLs in the AGPgart driver to support the new version of drm driver. 4.2 Description The AGPgart driver was introduced in PSARC 2004/151 [1]. This project is going to update the AGPgart driver to export more IOCTL interfaces. All these new interfaces will only be used by the drm driver [2] through the ldi interfaces, to set up or release device resource. 4.3 Interface Table ------------------------------------------------------------------------------------------------------------------ | Interface exported | Classifications | Comments | ------------------------------------------------------------------------------------------------------------------ | AGPIOC_FLUSHCHIPSET | Uncommitted | Flush chipset device. | | AGPIOC_PAGES_BIND | Uncommitted | Binds a collection of pages into AGP memory at the given offset. | | AGPIOC_PAGES_UNBIND | Uncommitted | Unbinds the given number of pages at the given offset. | | AGPIOC_PAGES_REBIND | Uncommitted | Rebinds the pages at resume time. | | INTEL_CHIPSET_FLUSH_SETUP | Uncommitted | Setup resources on intel chipset for flush operation. | | INTEL_CHIPSET_FLUSH | Uncommitted | Perform flushing on intel chipset. | ------------------------------------------------------------------------------------------------------------------ 4.4 References: [1] PSARC 2004/151 AGPgart Driver for Solaris x86 http://sac.eng/Archives/Projects/2004/20040223_sophia.li [2] PSARC/2004/801 DRI porting http://sac.sfbay.sun.com/Archives/CaseLog/arc/PSARC/2004/801/ 4.5 Documentation Change All these new interfaces are only used by drm driver in kernel level. There is no need to change any documentation about the AGPgart driver. 6. Resources and Schedule 6.4. Steering Committee requested information 6.4.1. Consolidation C-team Name: ON 6.5.
