2010-12-28Clean ISA_IO/ISA_IO_16 and VGA_IO/VGA_IO_16 attribute usage in PCI bus ↵rsun3
driver/PCI host bridge drivers/LPC/VGA device drivers. 1. Fix the incorrect definition of EFI_PCI_IO_ATTRIBUTE_VGA_IO_16 (does not conform to the UEFI spec) in PciIo.h. 2. Add missing definitions of ISA and VGA IO attributes in PCI Root Bridge IO protocol. 3. Improve the algorithm in the PCI bus driver to get PCI platform policy from PCI Platform Protocol and PCI Override Protocol. 4. Update the PCI bus driver to use the PCI platform policy to determine the supported attributes that are returned by the EFI_PCI_IO_PROTOCOL.Attributes() function. This is required by the PI spec. 5. Add a backward compatibility workaround for PCI VGA drivers in Option ROM, which typically sets VGA_IO without checking supported attributes. 6. Update the PCI host bridge driver in PcAtChipsetPkg to report VGA_IO_16 and ISA_IO_16 instead of VGA_IO/ISA_IO attributes. Modern chipsets don’t have hardware capability to control 10-bit or 16-bit decoding for ISA/VGA aliases. 7. Update LPC/VGA device drivers to check supported attributes of VGA_IO/VGA_IO_16 or ISA_IO/ISA_IO_16. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11204 6f19259b-4bc3-4df7-8a09-765794883524

2009-09-151. updated PCI/AGP Devices to check RemainingDevicePath in Supported() and ↵vanjeff
Start() functions. The main changes are: a. Add check validation of RemainingDevicePath in Supported() b. In Star() function, if RemaingDevicePath is the End of Device Path Node, don't create child device and return EFI_SUCCESS. 2. fixed one device path issue in ScsiBus driver. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9264 6f19259b-4bc3-4df7-8a09-765794883524

2009-06-30Do not update the GL-GD5446 DRAM Control register duringjljusten
InitializeGraphicsMode. The update of this register would cause the xorg-cirrus driver to mis-detect the size of video memory for the QEMU cirrus video device. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8690 6f19259b-4bc3-4df7-8a09-765794883524
2009-06-30Do not draw anything during DrawLogo.jljusten
Previously a series of diagonal color lines would be drawn to the screen, and then quickly replaced by the boot logo. Now the screen will remain black until the boot logo is shown. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@8689 6f19259b-4bc3-4df7-8a09-765794883524
2008-11-24Use the Controller handle to open the protocol, rather than thejljusten
NULL handle which was stored in Private->Handle. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@6689 6f19259b-4bc3-4df7-8a09-765794883524
2008-10-30Patch to remove STATIC modifier. This is on longer recommended by EFI ↵jji4
Framework coding style. All duplicated symbols has been renamed accordingly. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@6300 6f19259b-4bc3-4df7-8a09-765794883524
2008-01-031. add DxeI2c Library in OptionRomPkg.vanjeff
2. produce EFI_EDID_DISCOVERED_PROTOCOL and EFI_EDID_ACTIVE_PROTOCOL in CirrusLogic5430 module. 3. consume EFI_OVERRIDE_PROTOCOL in CirrusLogic5430 module. 4. setup video mode according to EDID information in CirrusLogic5430 module. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@4479 6f19259b-4bc3-4df7-8a09-765794883524
