* ArmVirtPkg: implement DT-based ArmGicArchLibArd Biesheuvel2015-07-283-1/+116
| | | | | | | | | | | | | | | | | | | | | Since it is arguably incorrect to infer the GIC revision from CPU ID and GIC feature registers on platforms that describe the GIC in the device tree, this implements the library class ArmGicArchLib tailored for such platforms. The supported GIC revision is retrieved from the dynamic PCD that is set based on the GIC DT node. This means this library can only execute post DXE core, but this is not a problem for any of the virt platforms.

* ArmPkg: split off ArmGicArchLib from ArmGicLibArd Biesheuvel2015-07-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | The current implementation of ArmGicGetSupportedArchRevision () that is used by all ARM platforms is entirely stateless (in order to support being executed from flash) so it needs to interrogate the hardware for the supported GIC revision upon each invocation. However, this statelessness is only needed for SEC type modules; in all other cases, we could easily determine the GIC revision once, and store the result in a global variable. In preparation of having separate early and normal versions, this patch introduces the ArmGicArchLib library class and default implementation, and moves the existing ArmGicGetSupportedArchRevision () into it.

* ArmVirtPkg: QemuFwCfgToPcdDxe: set SMBIOS entry point version dynamicallyLaszlo Ersek2015-07-263-0/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | (This patch parallels OvmfPkg commit 37baf06b (SVN r17676).) PcdSmbiosVersion controls the version number of the SMBIOS entry point table (and other, related things) that the universal "MdeModulePkg/Universal/SmbiosDxe" driver, providing EFI_SMBIOS_PROTOCOL, installs. The "virt" machine type of QEMU generates SMBIOS payload for the firmware to install. The payload includes the entry point table ("anchor" table). OvmfPkg/SmbiosPlatformDxe cannot install the anchor table (because that is the jurisdiction of the generic "MdeModulePkg/Universal/SmbiosDxe" driver); however, we can parse the entry point version from QEMU's anchor table, and instruct "MdeModulePkg/Universal/SmbiosDxe" to adhere to that version. As default for PcdSmbiosVersion we should keep the current 0x0300 value (ie. SMBIOS 3.0) from "MdeModulePkg/MdeModulePkg.dec"; that spec version was specifically created for ARM / AARCH64 needs.

* ArmVirtPkg: add QemuFwCfgToPcdDxeLaszlo Ersek2015-07-264-0/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many universal DXE drivers in edk2 can be controlled by setting dynamic PCDs. Such a PCD must be set before the consumer DXE driver is dispatched. (In general we assume that the DXE driver will consume the PCD in its entry point, or in the constructor of a library instance it links against. In special cases this requirement can be relaxed a bit, if we know that the DXE driver accesses the PCD only in a protocol member function that it exports.) On the QEMU platform, the PCD values to be set for the universal drivers are frequently derived from fw_cfg files that QEMU exports. In OvmfPkg we tend to handle this in the following way: - For IA32 and X64, OvmfPkg provides a QemuFwCfgLib instance that is usable in PEI. - In PlatformPei, fw_cfg files can be loaded and transformed to PCD values. - Any DXE driver is bound to be dispatched after the PEI phase is done. (In specific cases other ordering solutions might be possible, via Depex or protocol notify, etc.) In ArmVirtPkg/ArmVirtQemu, things differ a bit: - We don't have an ArmVirtPkg-specific ("Platform") PEIM. This is actually a good thing for now, so let's not introduce one just for this purpose. - Even if we had such a PEIM, it could not easily access fw_cfg: the MMIO addresses of the fw_cfg device are available only in the DTB that QEMU exports. (Accordingly, our QemuFwCfgLib instance is restricted to DXE_DRIVER modules: VirtFdtDxe parses the DTB, stores the fw_cfg addresses in PCDs, and then QemuFwCfgLib's constructor fetches those PCDs.) There are some examples in ArmVirtPkg where early code is forced to parse the DTB manually, but those examples are all painful, and our goal here (controlling universal DXE drivers) doesn't justify more of that pain. Therefore, introduce a separate, minimal DXE driver that is dispatched strictly after VirtFdtDxe (so that it can use QemuFwCfgLib), and strictly before other DXE drivers (so that it can set dynamic PCDs for them). Because VirtFdtDxe is already ordered with the APRIORI DXE file, it is simplest to do the same for the new driver. Actual fw_cfg files and PCDs shall be accessed in future patches.

* ArmVirtPkg: Make terminal type consistentHeyi Guo2015-07-161-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Change default terminal type to be consistent with default ConIn/ConOut device path, which is now determined by TTY_TERMINAL flag, TTYTERM or VT100. I can't say this is a bug, as we can pass the whole console device path to ConnectController, and TerminalDxe driver will pick up the terminal in the remaining device path. However, in rare circumstances, the console devices may be disconnected with the driver, and they will be ignored by ConPlatformDxe until we pass the device path explicitly just as BDS. Changing default terminal type to be the same with console device path could help serial terminal be reconnected with normal connect controller operation.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the ArmVirtPkg platforms built with the Intel BDS fail to signal the end-of-DXE event 'gEfiEndOfDxeEventGroupGuid' when entering the BDS phase, which results in some loss of functionality, i.e., variable reclaim in the VariableDxe drivers, and the splitting of the memory regions that is part of the recently added UEFI 2.5 properties table feature. As discussed on the edk2-devel mailing list here: http://thread.gmane.org/gmane.comp.bios.tianocore.devel/16088/focus=16109 it is up to the platform BDS to signal that event, since there may be platform specific ordering constraints with respect to the signalling of the event that are difficult to honor at the generic level. So add the SignalEvent () call to PlatformBdsInit () of ArmVirtPkg's PlatformBdsLib implementation for the Intel BDS.

For BS_Code, RT_Code and RT_Data, the increased preallocation results in the following reduction in the number of regions. 0x000040000000-0x00004000ffff [Loader Data | | | | | |WB|WT|WC|UC] - 0x000040010000-0x0000b66bbfff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000b66bc000-0x0000b66d0fff [Loader Data | | | | | |WB|WT|WC|UC] - 0x0000b66d1000-0x0000b6f6bfff [Loader Code | | | | | |WB|WT|WC|UC] - 0x0000b6f6c000-0x0000b6f6ffff [Reserved | | | | | |WB|WT|WC|UC]* - 0x0000b6f70000-0x0000b6f8ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000b6f90000-0x0000b6faffff [ACPI Reclaim Memory| | | | | |WB|WT|WC|UC]* - 0x0000b6fb0000-0x0000b6fcffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000b6fd0000-0x0000b701ffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* - 0x0000b7020000-0x0000b702ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000b7030000-0x0000b70cffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* - 0x0000b70d0000-0x0000b70dffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* + 0x000040010000-0x0000b680bfff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000b680c000-0x0000b6820fff [Loader Data | | | | | |WB|WT|WC|UC] + 0x0000b6821000-0x0000b70bbfff [Loader Code | | | | | |WB|WT|WC|UC] + 0x0000b70bc000-0x0000b70bffff [Reserved | | | | | |WB|WT|WC|UC]* + 0x0000b70c0000-0x0000b70dffff [ACPI Reclaim Memory| | | | | |WB|WT|WC|UC]* 0x0000b70e0000-0x0000b9f87fff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000b9f88000-0x0000bb921fff [Boot Data | | | | | |WB|WT|WC|UC] 0x0000bb922000-0x0000bb9bffff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000bb9c0000-0x0000bbbb0fff [Boot Data | | | | | |WB|WT|WC|UC] 0x0000bbbb1000-0x0000bbbeffff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000bbbf0000-0x0000bbf1ffff [Boot Data | | | | | |WB|WT|WC|UC] - 0x0000bbf20000-0x0000bedfffff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000bee00000-0x0000bf71ffff [Loader Data | | | | | |WB|WT|WC|UC] - 0x0000bf720000-0x0000bf7ccfff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000bf7cd000-0x0000bf92ffff [Boot Code | | | | | |WB|WT|WC|UC] - 0x0000bf930000-0x0000bf93ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* - 0x0000bf940000-0x0000bf95ffff [Conventional Memory| | | | | |WB|WT|WC|UC] - 0x0000bf960000-0x0000bf97ffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* + 0x0000bbf20000-0x0000bebfffff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000bec00000-0x0000bf51ffff [Loader Data | | | | | |WB|WT|WC|UC] + 0x0000bf520000-0x0000bf65cfff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000bf65d000-0x0000bf7bffff [Boot Code | | | | | |WB|WT|WC|UC] + 0x0000bf7c0000-0x0000bf84ffff [Runtime Code |RUN| | | | |WB|WT|WC|UC]* + 0x0000bf850000-0x0000bf86ffff [Conventional Memory| | | | | |WB|WT|WC|UC] + 0x0000bf870000-0x0000bf97ffff [Runtime Data |RUN| | | | |WB|WT|WC|UC]* 0x0000bf980000-0x0000bf997fff [Conventional Memory| | | | | |WB|WT|WC|UC] 0x0000bf998000-0x0000bf99afff [Boot Data | | | | | |WB|WT|WC|UC] 0x0000bf99b000-0x0000bf9aefff [Conventional Memory| | | | | |WB|WT|WC|UC] Contributed-under: TianoCore Contribution Agreement 1.0 Reviewed-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@17554 6f19259b-4bc3-4df7-8a09-765794883524
