[edk2] [PATCH v4 0/3] support multiple PL061 gpio controllers

by Haojian Zhuang

Changelog: v4: * Use 64-bit value on PL061 register base address. * Use fallback to be compatible with current PcdPL061GpioBase value when platform gpio driver isn't present. * Remove the dependancy on PL061. Move the dependancy to platform gpio driver instead. v3: * Remove GPIO_PIN_MASK_HIGH_8BIT() and GPIO_PIN_MASK_LOW_8BIT(). * Avoid to use MmioAnd8() on updating GPIO DATA register, since PL061 could access each bit by specified register offset. * Add PLATFORM_GPIO_CONTROLLER structure in embedded gpio. * Support multiple PL061 gpio controllers in one platform. v2: * Append the patch to fix gpio pin mask macro.

[PATCH v3 0/4] arm64: Add Xen boot support (via fdt)

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> - This adds support for the Xen boot on ARM specification for arm64. - Add and export some accessor functions of "loaded" flag and grub_linux_get_fdt function in include/grub/arm64/linux.h for xen boot. - Introduce xen_hypervisor, xen_linux, xen_initrd and xen_xsm to load different binaries for xen boot. Introduce xen_module to load common or custom module for xen boot. - This Xen boot support is a separated module for aarch64, but reuse the existing code of devicetree in linux module. - Add the support of xen_hypervisor, xen_linux and xen_initrd in util/grub.d/20_linux_xen.in - Add the introduction of all xen boot commands in docs/grub.texi - The example of this support is <How to boot Xen with GRUB on AArch64 the Foundation FVP model> https://wiki.linaro.org/LEG/Engineering/Grub2/Xen_booting_on_Foundation_FVP… Changelog: v3: create separate module for xen boot: xen_boot create separate commands for different types of module delete order-dependent for commands of xen module simplify the code v2: remove the patches which have been accepted. according to Vladimir's suggestion, change the command manes and relevant code: multiboot-->xen_hypervisor module-->xen_module improve the option parsing support for xen_hypervisor/xen_module commands. add a patch for adding xen_hypervisor/xen_module support in util/grub.d/20_linux_xen.in. update docs/grub.texi patch for the new command names. v1: The first version upstream patchset to grub-devel mailing list Fu Wei (4): arm64: Add and export some accessor functions for xen boot arm64: Add xen_boot module file * util/grub.d/20_linux_xen.in: Add support of the XEN boot on aarch64 arm64: Add the introduction of xen boot commands in docs/grub.texi docs/grub.texi | 56 ++++ grub-core/Makefile.core.def | 7 + grub-core/loader/arm64/linux.c | 13 + grub-core/loader/arm64/xen_boot.c | 685 ++++++++++++++++++++++++++++++++++++++ include/grub/arm64/linux.h | 6 +- util/grub.d/20_linux_xen.in | 16 +- 6 files changed, 779 insertions(+), 4 deletions(-) create mode 100644 grub-core/loader/arm64/xen_boot.c -- 1.8.3.1

[PATCH] MdePkg/BaseSynchronizationLib: fix return value

by Haojian Zhuang

Fix the wrong return value of both InternalSyncIncrement() and InternalSyncDecrement(). The return value shouldn't be the address of input parameter. It should be the updated value of input parameter instead.

[RFC] Adaptively change serial terminal polling interval

by Heyi Guo

Hi folks, In MdeModulePkg/Universal/Console/TerminalDxe/TerminalDxe.inf, the polling interval is fixed by macro: #define KEYBOARD_TIMER_INTERVAL 200000 // 0.02s However, this may cause fast input truncation on some platform. For example, we have a serial console with below features: 1. Baud rate: 115200 2. FIFO depth of UART device: 32 If we want to capture all input, we need to poll with the interval of 32 / (115200 / (8 + 1 + 1)) = 2.8 ms, 8 + 1 + 1 for data bits + start bit + stop bit. So, I suppose to use a PCD to set the interval statically, or calculate from serial IO protocol IO Mode data dynamically, which contains FIFO depth and data bits, etc. Please let me know your comments. Thanks. (If you see my another mail like this, please ignore that; this one is the final version; sorry for the noise)
