2024-09-13selftests: vDSO: open code basic chacha instead of linking to libsodiumJason A. Donenfeld
Linking to libsodium makes building this test annoying in cross compilation environments and is just way too much. Since this is just a basic correctness test, simply open code a simple, unoptimized, dumb chacha, rather than linking to libsodium. This also fixes a correctness issue on big endian systems. The kernel's random.c doesn't bother doing a le32_to_cpu operation on the random bytes that are passed as the key, and consequently neither does vgetrandom-chacha.S. However, libsodium's chacha _does_ do this, since it takes the key as an array of bytes. This meant that the test was broken on big endian systems, which this commit rectifies.

2024-09-13random: vDSO: move prototype of arch chacha function to vdso/getrandom.hJason A. Donenfeld
Having the prototype for __arch_chacha20_blocks_nostack in arch/x86/include/asm/vdso/getrandom.h meant that the prototype and large doc comment were cloned by every architecture, which has been causing unnecessary churn. Instead move it into include/vdso/getrandom.h, where it can be shared by all archs implementing it. As a side bonus, this then lets us use that prototype in the vdso_test_chacha self test, to ensure that it matches the source, and indeed doing so turned up some inconsistencies, which are rectified here.

2024-09-13selftests: vDSO: ensure vgetrandom works in a time namespaceJason A. Donenfeld
After verifying that vDSO getrandom does work, which ensures that the RNG is initialized, test to see if it also works inside of a time namespace. This is important to test, because the vvar pages get swizzled around there. If the arch code isn't careful, the RNG will appear uninitialized inside of a time namespace. Because broken code makes the RNG appear uninitialized, test that everything works by issuing a call to vgetrandom from a fork in a time namespace, and use ptrace to ensure that the actual syscall getrandom doesn't get called. If it doesn't get called, then the test succeeds. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>

2024-09-13PCI: qcom: Add equalization settings for 16.0 GT/sShashank Babu Chinta Venkata
During high data transmission rates such as 16.0 GT/s, there is an increased risk of signal loss due to poor channel quality and interference. This can impact receiver's ability to capture signals accurately. Hence, as signal compensation is achieved through appropriate lane equalization, apply lane equalization settings at both transmitter and receiver which results in an increase in the PCIe signal strength. While at it, modify the pcie-tegra194 driver to make use of the common GEN3_EQ_CONTROL_OFF definitions in pcie-designware.h.

2024-09-13PCI: dwc: Always cache the maximum link speed value in dw_pcie::max_link_speedManivannan Sadhasivam
Currently, the dw_pcie::max_link_speed has a valid value only if the controller driver restricts the maximum link speed in the driver or if the platform does so in the devicetree using the 'max-link-speed' property. But having the maximum supported link speed of the platform would be helpful for the vendor drivers to configure any link specific settings. So in the case of non-valid value in dw_pcie::max_link_speed, just cache the hardware default value from Link Capability register. While at it, remove the 'max_link_speed' argument to the dw_pcie_link_set_max_speed() function since the value can be retrieved within the function.

The 'link_gen' field is now holding the maximum supported link speed set either by the controller driver or by DT through 'max-link-speed' property. However, the name 'link_gen' sounds like the negotiated link speed of the PCIe link. So rename it to 'max_link_speed' to make it clear that it holds the maximum supported link speed of the controller.

2024-09-13PCI: qcom-ep: Enable controller resources like PHY only after refclk is ↵Manivannan Sadhasivam
available qcom_pcie_enable_resources() is called by qcom_pcie_ep_probe() and it enables the controller resources like clocks, regulator, PHY. On one of the new unreleased Qcom SoC, PHY enablement depends on the active refclk. And on all of the supported Qcom endpoint SoCs, refclk comes from the host (RC). So calling qcom_pcie_enable_resources() without refclk causes the NoC (Network On Chip) error in the endpoint SoC and in turn results in a whole SoC crash and rebooting into EDL (Emergency Download) mode which is an unrecoverable state. But qcom_pcie_enable_resources() is already called by qcom_pcie_perst_deassert() when PERST# is deasserted, and refclk is available at that time. Hence, remove the unnecessary call to qcom_pcie_enable_resources() from qcom_pcie_ep_probe() to prevent the above mentioned crash. It should be noted that this commit prevents the crash only under normal working condition (booting endpoint before host), but the crash may also occur if PERST# assert happens at the wrong time. For avoiding the crash completely, it is recommended to use SRIS mode which allows the endpoint SoC to generate its own refclk. The driver is not supporting SRIS mode currently, but will be added in the future.

Endpoint Add reg-name: "dbi2", "atu" for i.MX8M PCIe Endpoint. For i.MX8M PCIe EP, the dbi2 and atu addresses are pre-defined in the driver. This method is not good. In commit b7d67c6130ee ("PCI: imx6: Add iMX95 Endpoint (EP) support"), Frank suggests to fetch the dbi2 and atu from DT directly. This commit is preparation to do that for i.MX8M PCIe EP. These changes wouldn't break driver function. When "dbi2" and "atu" properties are present, i.MX PCIe driver would fetch the according base addresses from DT directly. If only two reg properties are provided, i.MX PCIe driver would fall back to the old method.

2024-09-13pmdomain: core: Reduce debug summary table widthGeert Uytterhoeven
Commit 9094e53ff5c86ebe ("pmdomain: core: Use dev_name() instead of kobject_get_path() in debugfs") severely shortened the names of devices in a PM Domain. Now the most common format[1] consists of a 32-bit unit-address (8 characters), followed by a dot and a node name (20 characters for "air-pollution-sensor" and "interrupt-controller", which are the longest generic node names documented in the Devicetree Specification), for a typical maximum of 29 characters. This offers a good opportunity to reduce the table width of the debug summary: - Reduce the device name field width from 50 to 30 characters, which matches the PM Domain name width, - Reduce the large inter-column space between the "performance" and "managed by" columns. Visual impact: - The "performance" column now starts at a position that is a multiple of 16, just like the "status" and "children" columns, - All of the "/device", "runtime status", and "managed by" columns are now indented 4 characters more than the columns right above them, - Everything fits in (one less than) 80 characters again ;-) [1] Note that some device names (e.g. TI AM335x interconnect target modules) do not follow this convention, and may be much longer, but these didn't fit in the old 50-character column width either.

2024-09-13pmdomain: core: Move mode_status_str()Geert Uytterhoeven
Move mode_status_str() below perf_status_str(), to make declaration order match calling order of the various *_status_str() helpers. While at it, add a blank line for consistency among the three helpers.

2024-09-13pmdomain: core: Fix "managed by" alignment in debug summaryGeert Uytterhoeven
The "performance" column contains variable-width values. Hence when their printed values contain more than one digit, all values in successive columns become misaligned. Fix this by formatting it as a fixed-width field. Adjust successive spaces and field widths to retain the exiting layout.

2024-09-13pmdomain: core: Harden inter-column space in debug summaryGeert Uytterhoeven
The inter-column space in the debug summary is two spaces. However, in one case, the extra space is handled implicitly in a field width specifier. Make inter-column space explicit to ease future maintenance.

The size of the mux stride was off by one, which could result in invalid pin configuration on the device side or invalid state readings on the software side. While on it also update the code and: - Increase the mux stride size to 16 - Align the virtual muxed regmap range to 16 - Start the regmap window at the selector - Mark reserved registers as not-readable Fixes: 8670de9fae49 ("pinctrl: cy8c95x0: Use regmap ranges") Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reported-by: Andy Shevchenko <andy@kernel.org> Reviewed-by: Andy Shevchenko <andy@kernel.org> Link: https://lore.kernel.org/20240902072859.583490-1-patrick.rudolph@9elements.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
