| 2022-10-12 | LoongArch: Use TLB for ioremap() | Huacai Chen | 1 | -0/+15 | |
| We can support more cache attributes (e.g., CC, SUC and WUC) and page protection when we use TLB for ioremap(). The implementation is based on GENERIC_IOREMAP. The existing simple ioremap() implementation has better performance so we keep it and introduce ARCH_IOREMAP to control the selection. We move pagetable_init() earlier to make early ioremap() works, and we modify the PCI ecam mapping because the TLB-based version of ioremap() will actually take the size into account.
