Subject: [PATCH v5 0/4] ARM: Add support for Hisilicon Kunpeng L3 cache controller
Date: Sat, 16 Jan 2021 11:27:36 +0800 [thread overview]
Message-ID: <20210116032740.873-1-thunder.leizhen@huawei.com> (raw)
v4 --> v5:
1. Add SoC macro ARCH_KUNPENG50X, and the Kunpeng L3 cache controller only enabled
on that platform.
2. Require the compatible string of the Kunpeng L3 cache controller must have a
relevant name on a specific SoC. For example:
compatible = "hisilicon,kunpeng509-l3cache", "hisilicon,kunpeng-l3cache";
v3 --> v4:
Rename the compatible string from "hisilicon,l3cache" to "hisilicon,kunpeng-l3cache".
Then adjust the file name, configuration option name, and description accordingly.
v2 --> v3:
Add Hisilicon L3 cache controller driver and its document. That's: patch 2-3.
v1 --> v2:
Discard the middle-tier functions and do silent narrowing cast in the outcache
hook functions. For example:
-static void l2c220_inv_range(unsigned long start, unsigned long end)
+static void l2c220_inv_range(phys_addr_t pa_start, phys_addr_t pa_end)
{
+ unsigned long start = pa_start;
+ unsigned long end = pa_end;
v1:
Do cast phys_addr_t to unsigned long by adding a middle-tier function.
For example:
-static void l2c220_inv_range(unsigned long start, unsigned long end)
+static void __l2c220_inv_range(unsigned long start, unsigned long end)
{
...
}
+static void l2c220_inv_range(phys_addr_t start, phys_addr_t end)
+{
+ __l2c220_inv_range(start, end);
+}
Zhen Lei (4):
ARM: LPAE: Use phys_addr_t instead of unsigned long in outercache
hooks
ARM: hisi: add support for Kunpeng50x SoC
dt-bindings: arm: hisilicon: Add binding for Kunpeng L3 cache
controller
