* OptionRomPkg: Ax88772b: Fixing register access issue in Apple Eth AdapterShivamurthy Shastri2016-03-313-9/+51
| | | | | | | | | | | | The USB command CMD_RXQTC ("RX Queue Cascade Threshold Control") tries to access the register and is always failing when using the Apple Ethernet adapter. It is fixed by checking flag before sending command.

| | | | | | | | | | | | | | | This BltLib implementation will act on the BltLib functions by directly manipulating a memory framebuffer. Therefore, it should be usable by a Graphics Output Protocol (GOP) driver to easily implement the GOP Blt function whenever a memory framebuffer is available. It can also be used in any situation where code would prefer to not call the GOP Blt function, and would rather update the framebuffer directly. (Assuming a framebuffer is available for the graphics device.) git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11521 6f19259b-4bc3-4df7-8a09-765794883524
* OptionRomPkg: Add BltLib definitionjljusten2011-04-122-0/+268
| | | | | | | | | | | | | | | | | | | | | | | | | | | This library is intended to make it easy to perform blt operations on a GOP framebuffer without using the GOP Blt function. There can be two main forms of implementations of this library: 1) A library which interfaces directly with a framebuffer, and has no dependence on the GOP protocol. Once configured with the framebuffer parameters, it can operate directly on the framebuffer. 2) A library which interfaces with the GOP protocol. In this case this library provides a convenience layer and allows blt code to look cleaner. Potential uses for this library: * Video driver with a framebuffer will not need to implement GOP Blt function itself. Instead it can utilize an implementation of this library as described in #1 above. * OS Loader code which would like to easily use the GOP framebuffer after Exit Boot Services. This would use a library instance as described in #1 above. * Any other code which would like to call GOP blt, but simplify the code with the more convenient functions provided by this library interface. (Using a library as described in #2 above.) git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11520 6f19259b-4bc3-4df7-8a09-765794883524

In order to support the degree of flexibility, the DebugLib needs to use library to abstract the get/set operations to the filter mask. 1) Add default mappings for the DebugPrintErrorLevelLib to the DSC file for this package. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11372 6f19259b-4bc3-4df7-8a09-765794883524
* Clean ISA_IO/ISA_IO_16 and VGA_IO/VGA_IO_16 attribute usage in PCI bus ↵rsun32010-12-281-6/+26
| | | | | | | | | | | | | | 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
