2018-08-31Make kmalloc'ed memory really DMA-safeMasahiro Yamada
In Linux, the memory returned by kmalloc() is DMA-capable. However, it is not true in U-Boot. At a glance, kmalloc() in U-Boot returns address aligned with ARCH_DMA_MINALIGN. However, it never pads the allocated memory. This half-way house is completely useless because calling kmalloc() and malloc() in this order causes a cache sharing problem. Change the implementation to call malloc_cache_aligned(), which allocates really DMA-capable memory. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2018-08-21efi: Fix truncation of constant valueEugeniu Rosca
Starting with commit 867a6ac86dd8 ("efi: Add start-up library code"), sparse constantly complains about truncated constant value in efi.h: include/efi.h:176:35: warning: cast truncates bits from constant value (8000000000000000 becomes 0) This can get quite noisy, preventing real issues to be noticed: $ make defconfig *** Default configuration is based on 'sandbox_defconfig' $ make C=2 -j12 2>&1 | grep truncates | wc -l 441 After the patch is applied: $ make C=2 -j12 2>&1 | grep truncates | wc -l 0 $ sparse --version v0.5.2 Following the suggestion of Heinrich Schuchardt, instead of only fixing the root-cause, I replaced the whole enum of _SHIFT values by ULL defines.

2018-08-20efi_loader: fix a parameter check at CreateEvent()AKASHI Takahiro
The commit 21b3edfc9644 ("efi_loader: check parameters of CreateEvent") enforces a strict parameter check at CreateEvent(). On the other hand, UEFI specification version 2.7, section 7.1, says: The EVT_NOTIFY_WAIT and EVT_NOTIFY_SIGNAL flags are exclusive. If neither flag is specified, the caller does not require any notification concerning the event and the NotifyTpl, NotifyFunction, and NotifyContext parameters are ignored. So the check should be mitigated so as to comply with the specification. Without this patch, EDK2's Shell.efi won't be started.

2018-08-20Revert "efi_loader: efi_allocate_pages is too restrictive"Stephen Warren
This reverts commit aa909462d01866354f4cd4534db5f571c2cf1fbb. This change caused "dhcp filename" to crash the system on p2371-2180 (Jetson TX1), for example when running test/py. Reverting this change isn't optimal, but at least restores TX1 to a working state. In the future, we should: a) Fix whatever problem causes the crash with this patch applied. This needs further discussion, so isn't something we can immediately do. b) Undo the revert; re-apply the original patch to efi_allocate_pages.

2018-07-25efi_loader: Expose U-Boot addresses in memory map for sandboxAlexander Graf
We currently expose host addresses in the EFI memory map. That can be bad if we ever want to use sandbox to boot strap a real kernel, because then the kernel would fetch its memory table from our host virtual address map. But to make that use case work, we would need to have full control over the address space the EFI application sees. So let's expose only U-Boot addresses to the guest until we get to the point of allocation. EFI's allocation functions are fun - they can take U-Boot addresses as input values for hints and return host addresses as allocation results through the same uint64_t * parameter. So we need to be extra careful on what to pass in when. With this patch I am successfully able to run the efi selftest suite as well as grub.efi on aarch64.
