From 2ceb8be2cc3e7249ca671009c017d53f05b8925a Mon Sep 17 00:00:00 2001 From: Blazej Kucman Date: Fri, 13 Mar 2026 11:47:41 +0100 Subject: [PATCH] imsm: Update VROC branding for new ownership MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Update VROC branding for new ownership by Graid Technology Inc. VROC (Virtual RAID on CPU) technology has been acquired by Graid Technology Inc. This patch updates the branding and references to reflect the new ownership while maintaining technical accuracy. The rebranding introduces new versioning starting from version 26. VROC version 9.x and earlier will continue to be displayed as "Intel(R) Virtual RAID on CPU" to accurately reflect their origin. Starting with version 26, the platform is displayed as "VROC(TM) by Graid Technology Inc." Changes include: - Updated maintainer information in README.md from Intel® to Graid Technology Inc. for IMSM metadata format, - Changed documentation URL to point to Graid's VROC documentation, - Updated platform display string to show "VROC(TM) by Graid Technology Inc." for version 26 and later, - Removed Intel branding from VROC-specific error messages. The following references are intentionally preserved: - IMSM metadata format name (Intel(R) Matrix Storage Manager) remains unchanged as it represents the established metadata format, - References to "Intel controller" and "Intel Platform" are maintained where they specifically, refer to Intel hardware components, hardware-specific references remain accurate and unchanged.
