| | | | | | | | | | | | | | | | | | | | | | For concerns about security, the register to enable/disable IOMMU of SMI LARB should only be configured in secure world. Thus, we add some SMC command for multimedia master to enable/disable MM IOMMU in ATF by setting the register of SMI LARB. This function is prepared for MT8188.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The next generation (revision 1) of the DFL EMIF feature device requires support for more than 4 memory banks. It does not support the selective clearing of memory banks. A capability register replaces the previous control register, and contains a bitmask to indicate the presence of each memory bank. This bitmask aligns with the previous control register bitmask that served the same purpose. The control and capability registers are treated like a C Union structure in order to support both the new and old revisions of the EMIF device.

As attached data already already exists, attaching data with the same tag will fail. Address this problem by ignoring nodes that have been already tagged.

Additionally lock_pages() doesn't check for pin_user_pages_fast() having been completely successful, resulting in potentially not locking all pages into memory. This could result in sporadic failures when using the related memory in user mode. Fix all of that by calling unlock_pages() always with the real number of pinned pages, which will be zero in case pages being NULL, and by checking the number of pages pinned by pin_user_pages_fast() matching the expected number of pages.

However, if if vc_resize() failed, current implementation doesn't revert changes for font size, and this causes inconsistent state. syzbot reported unable to handle page fault due to this issue [1]. syzbot's repro uses fault injection which cause failure for memory allocation, so vc_resize() failed. This patch fixes this issue by properly revert changes for font related date when vc_resize() failed.

Along the path, `var->pixclock` won't be modified. This function checks whether reciprocal of `var->pixclock` is too high. If `var->pixclock` is zero, there will be a divide by zero error.
