Siyuan, Some minor comments to the patch:
1. Add perform parameter check for ImageType in HttpBootGetFileFromCache(). 2. Update function description of HttpBootStart/HttpBootLoadFile for EFI_INVALID_PARAMETER since we now add further check. 3. Add EFI_INVALID_PARAMETER to function description of HttpBootCheckImageType 4. In HttpBootCheckImageType, ImageType is checked but others are skipped. Not necessary? 5. Is EFI_NOT_FOUND irrelevant to HttpBootRegisterRamDisk? I see EFI_UNSUPPORTED returned below. Please double check. Others are good to me.

This patch updates the HTTP Boot driver to support the download and boot a RAM disk image from HTTP server. The HTTP RAM disk boot is described in section 23.7 "HTTP Boot" in UEFI 2.6. HTTP server could provide either an UEFI image or a RAM disk image for the HTTP boot client to use. The RAM disk image must contain a UEFI compliant file system in it. HTTP boot driver will identify the image type either by the "Content-Type" entity header filed or by the file name extension as below: "application/efi" or *.efi -> EFI Image *.iso -> CD/DVD Image *.img -> Virtual Disk Image Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Fu Siyuan <siyuan...@intel.com> Cc: Ye Ting <ting...@intel.com> Cc: Wu Jiaxin <jiaxin...@intel.com> Cc: El-Haj-Mahmoud Samer <samer.el-haj-mahm...@hpe.com> --- NetworkPkg/HttpBootDxe/HttpBootClient.c | 35 ++++++-- NetworkPkg/HttpBootDxe/HttpBootClient.h | 5 +- NetworkPkg/HttpBootDxe/HttpBootDxe.h | 19 +++++ NetworkPkg/HttpBootDxe/HttpBootDxe.inf | 3 + NetworkPkg/HttpBootDxe/HttpBootImpl.c | 130 ++++++++++++++++++----------- NetworkPkg/HttpBootDxe/HttpBootSupport.c | 135 +++++++++++++++++++++++++++++++ NetworkPkg/HttpBootDxe/HttpBootSupport.h | 44 ++++++++++ 7 files changed, 319 insertions(+), 52 deletions(-) diff --git a/NetworkPkg/HttpBootDxe/HttpBootClient.c b/NetworkPkg/HttpBootDxe/HttpBootClient.c index 0c47293..0e30b22 100644 --- a/NetworkPkg/HttpBootDxe/HttpBootClient.c +++ b/NetworkPkg/HttpBootDxe/HttpBootClient.c @@ -570,6 +570,7 @@ HttpBootFreeCacheList ( @param[out] Buffer The memory buffer to transfer the file to.
